    INTRODUCTION

    The genus Lantana (Verbenaceae) as described

    by Linnaeus in 1753 contained seven species, six from

    South America and one from Ethiopia. Lantana is

    mostly native to subtropical and tropical America, but a

    few taxa are indigenous to tropical Asia and Africa. It

    now occurs in approximately 50 countries where several

    species are cultivated under hundreds of cultivar names

    [1]. The genus is a difficult one to classify taxonomically

    since species are not stable and hybridisation is

    widespread, shape of inflorescence changes with age, and

    flower colours vary with age and maturity [2]. Lantana

    camara L. (Verbanaceae), commonly known as wild or

    red sage is the most widespread species of this genus and

    regarded both as a notorious weed and a popular

    ornamental garden plant [3]. Lantana camara grows

    luxuriantly at elevations up to 2000 m in tropical, sub-

    tropical and temperate regions [4]. It is a woody

    straggling plant with various flower colours, red, pink,

    white, yellow and violet. The stems and branches are

    sometimes armed with prickles or spines [1].

    The plant is native to tropical and subtropical

    America. Dutch explorers introduced it into the

    Netherlands from Brazil in the late 1600s and later

    explorers from other countries brought seeds to Europe,

    Great Britain and North America. Following its

    introduction into Hawaii as a garden flower, it soon

    spread to the islands of the Pacific, Australia and

    southern Asia. In the 18th and 19th century, nurserymen

    commercialised and popularised many colourful forms

    and it is now cultivated world-wide as an ornamental

    plant. Of the 650 cultivar names in the genus, the

    majority are associated with the L. camara complex. The

    plant is an aggressive, obligate out breeder weed that has

    invaded vast expanses of pastures, orchards and forest

    areas in many tropical and subtropical regions [1]. It has

    been regarded as one of the 10 most noxious weeds in the

    world [4].

    ABSTRACT

    In recent years, focus on plant research has increased all over the world and large body of evidence has

    collected to show immense potential of medicinal plants used in various traditional systems. In the traditional

    systems of medicine, most of the remedies were taken from plants and they were proved to be useful. Lantana

    camara L, belong to the family Verbenaceae, is such a herb used traditionally to treat various ailments like tetanus,

    rheumatism, malaria, cough, fevers, cold, rheumatisms, asthma to mention a few. Many phytochemical investigations

    have been done on this plant. The plant was reported to contain various compounds like triterpenoids, proteins,

    carbohydrates, lactones, furfural, flavonoids, amino acids, alkaloids, saponins, glycosides, tannins, steroids. Many of

    the traditional uses have been scientifically proved. The ethnopharmacology, phytochemistry and pharmacology of Lantana camara L. are discussed in this review.

    Apart from its popularity as a garden plant, L.

    camara is said to form a useful hedge and to provide a

    good preparation for crops, covering the ground with fine

    leaf mulch [2]. It improves the fertility of rocky, grave, or

    hard laterite soils, enriches the soil, serves to retain humus

    in deforested areas and checks soil erosion. Lantana

    leaves and twigs are often used in India as green mulch.

    The ash is rich in potassium and manganese which is

    useful in manuring coconut trees [1]. In tropical countries,

    the ripe blue black berries are eaten, but ingestion of the

    green berry has led to human fatalities. L. camara is

    poisonous to stocks and humans [5, 6]. L. camara is

    poisonous to stocks and humans. Ingestion of leaves from

    L. camara, by grazing animals produces photodermatitis,

    jaundice, liver damage and death [7].

    This review features the plant biography,

    ethnopharmacology, phytochemistry and pharmacology

    of Lantana camara L. are considered. This information

    provides a basis for the evaluation of Lantana camara as

    a useful source of renewable material.

    PLANT BIOGRAPHY

    Botanical name:

    Lantana camara L. Family: Verbenaceae

    Synonyms

    Camara vulgaris and Lantana scabrida

    Common names

    It is commonly called as sleeper weed, lantana, and wild

    sage. The plant is distributed all over the world and

    occurs widely in the Asia-Pacific region, Australia, New

    Zealand, Central and South America, West Indies and

    Africa. Linguistic variations lead in various names to the

    plant.

    Some of them are given below.

    English: Common Lantana

    Hindi : Raimuniya

    Tamil : Unni chedi

    Malayalam: Arippoo

    Telugu: Pulikampa

    Marathi: Tantani

    HABIT

    Lantana camara is a low, erect or subscandent,

    vigorous shrub which can grow to 2 - 4 meters in height.

    The leaf is ovate or ovate oblong, 2 - 10 cm long and 2 - 6

    cm wide, arranged in opposite pairs. Leaves are bright

    green, rough, finely hairy, with serrate margins and emit a

    pungent odour when crushed. The stem in cultivated

    varieties is often non- thorny and in weedy varieties with

    recurved prickles. It is woody, square in cross section,

    hairy when young, cylindrical and up to 15 cm thick as it

    grows older. Lantana is able to climb to 15 m with the

    support of other vegetation. Flower heads contain 20 - 40

    flowers, usually 2.5 cm across; the colour varies from

    white, cream or yellow to orange pink, purple and red.

    Flowering occurs between August and March, or all year

    round if adequate moisture and light are available.

    Pollinators include lepidopteran species and thrips. The

    fruit is a greenish blue-black colour, 5 - 7 mm in

    diameter, drupaceous, shining, with two nutlets; seed

    setting takes place between September to May with 1 - 20

    seeds on each flower head. Mature plants produce up to

    12,000 seeds annually. Seed germination occurs when

    sufficient moisture is present; germination is reduced by

    low light conditions. The root system is very strong with a

    main taproot and a mat of many shallow side roots [8].

    ETHNOPHARMACOLOGY

    The plant has been used in many parts of the

    world to treat a wide variety of disorders [1]. The leaves

    of the plant are boiled like tea and the decoction is a

    remedy against cough [9]. A decoction of the plant is

    given as treatment for tetanus, rheumatism, malaria and

    ataxy of abdominal viscera. Pounded leaves are applied to

    cuts, ulcers and swellings; a decoction of the leaves is

    used as a lotion for wound [10]. Lantana camara found

    use in folk remedies for cancers and tumours. A tea

    prepared from the leaves and flowers was taken against

    fever, influenza and

    stomach-ache. In Central and South America, the

    leaves were made into a poultice to treat sores, chicken

    pox and measles. Fevers, cold, rheumatisms, asthma and

    high blood pressure were treated with preparations from

    the plant. In Ghana, infusion of the whole plant was used

    for bronchitis and the powdered root in milk was given to

    children for stomach-ache [1, 11]. It has been claimed that

    a steroid, lancamarone, from the leaves exhibited

    cardiotonic properties [12]. Traditionally it is also used as

    a tonic, in abdominal pains, as anthelmintic and

    Insecticide [13]. In Asian countries, leaves were used to

    treat cuts, rheumatisms and ulcers [14].

    PHYTOCHEMISTRY

    All the plant parts were investigated for the

    chemical constituents. The plant was reported to contain

    various compounds like Triterpenoids [14, 15], proteins

    [16], carbohydrates [17], lactones [18], furfural [19],

    flavonoids [14, 20] amino acids [13], alkaloids, saponins,

    glycosides, tannins and steroids [14].

    GC and GC/MS analyses of the hydro distilled

    essential oil from the leaves of Lantana camara showed

    large amount of sesquiterpene, mainly -caryophyllene (35.70%) and caryophyllene oxide (10.04%). The tested

    essential oil showed good fumigant activity. The essential

    oil of L. camara showed a wide spectrum of antibacterial,

    antimicrobial and antifungal activities [21]. For L.

    camara, the maximum yield obtained by hydrodistillation

  • Inter. J. of Phytotherapy / Vol 2 / Issue 2 / 2012 / 66-73.

    ~ 68 ~

    from the leaves reached 0.2% and, from the flowers, up to

    0.6% [22, 23]. A sample obtained from L. camara trees

    grown in Brazil had a terpene-like, leathery, fatty, and

    sweaty odour. The constituents were found to be mainly

    bisabolene derivatives (65%) with only traces of

    monoterpenes. The sesquiterpenes present were -curcumene (1.5%), E-nuciferal and Z-nuciferol (3.9%), (-

    )-ar-curcumen-15-al (5.6%), -curcumene (8%), ar-curcumene (9.7%), (-)--b-bisabolol (10%), (-)- -curcumen-15-al (14.9%) [1]. Bicyclogermacrene (26.1%),

    caryophyllene (24.4%), germacrene D (19.2%) and

    valecene (12.0%) also have been isolated from the

    essential oil [24].

    Six phenolic compounds such as salicylic acid,

    gentisic acid, -resorcylic acid, coumarin, ferulic acid, and 6-Me coumarin were identified in L. camara extract

    by HPLC [25]. Three new pentacyclic triterpenoids,

    lantacin, camarin, and camarinin, were isolated from the

    aerial parts of L.camara. The structures were elucidated

    by chemical transformation, HR-EI mass spectrometry,

    and NMR spectroscopy, including 1D (1Hand 13C-NMR)

    and 2D (1H, 1H-COSY, NOESY, H, 1HTOCSY, J-

    resolved, HMQC, and HMBC) experiments [26].

    The active fractions of the leaves, twigs, stems,

    and roots of L. camara yielded known oleanonic acid,

    lantadene A, and oleanolic acid, which were very toxic to

    brine shrimp larvae [27]. Lantanilic acid, camaric acid

    and oleanolic acid,were isolated from the methanol

    extract of the aerial parts of L. camara through bioassay

    guided fractionation, all of which possess nematocidal

    activity. [28, 29]. Two triterpenoids named lantadene A

    and lantadene B were isolated from the chloroform extract

    fraction of leaves of L. camara [30,31,32,33,34].

    Two novel triterpenoids such as 3, 19-dihydroxyursan-28-oic acid and 21, 22 -epoxy-3-hydroxyolean-12-en-28-oic acid have been isolated from

    the roots of L. camara [35]. Two new compounds,

    lantanoside and lantanone, and the known compounds

    linaroside and camarinic acid were isolated from the

    aerial parts of L. camara. Camarolide and lancamaric

    acid, two new constituents also have been isolated from

    the aerial parts of L. camara [36]. The triterpenoid lantic

    acid was isolated from L. camara plants cultivated in

    Egypt, which possess strong antibacterial activity aganist

    Gram-positive and Gram-negative bacteria [37, 38, 39,

    40]. Three new pentacyclic triterpenoids were isolated

    from the aerial parts of L. camara namely camaryolic

    acid, methylcamaralate and camangeloyl acid [41]. A new

    ursane derivative was isolated from the leaves of L.

    camara and its structure elucidated as 3, 24- dioxo-urs-

    12-en-28-oic acid by spectral analysis [42]. Three new

    pentacyclic triterpenes, ursoxy acid, methyl ursoxylate

    and ursangilic acid along with oleanolic acid acetate were

    also isolated from the aerial parts of L. camara [43].

    Ursethoxy acid, a new pentacyclic triterpene, was isolated

    from the aerial parts of L. camara. Its structure has been

    elucidated as 3, 25-epoxy-3-ethoxy-urs-12-en-28-oic acid through extensive NMR studies [43].

    The triterpenoids betulonic acid, icterogenin and

    betulinic acid the known flavonoid, -sitosterol 3-O--D-glucoside and a mixture of campesterol, stigmasterol and

    -sitosterol were isolated from the stems of pink-flowering L. camara [44].

    The methanol extract of L. camara revealed trace

    quantities (0.00004-0.0002%) of euphane triterpene

    lactones. Five active compounds were isolated and the

    structure of these compounds was determined by means

    of spectroscopic methods. All compounds were potent

    inhibitors of human thrombin [45]. A well known

    phenylethanoid, verbascoside has been isolated from L.

    camara [46]. The Z-isomer of verbascoside, lantanaside

    has also been found to co-occur with verbascoside in L.

    camara [47]. Isoverbascoside which often co-occurs with

    verbascoside, martynoside, isonuomioside A,

    derhamnosylverbascoside and calceolarioside E has been

    isolated from L. camara [48].

    Two triterpenes, 25-hydroxy-3-oxoolean-12-en-

    28-oic acid and hederagenin have been isolated from L.

    camara [49]. 12-oleanane triterpenoid and 12-ursane type triterpenoid, camarilic acid and camaracinic acid

    have been reported from the aerial parts of L. camara

    collected in Pakistan [50]. A number of triterpenoids were

    isolated from the roots of L. camara and they were

    identified as lantanolic acid, 22-hydroxy-oleanonic acid and lantaiursolic acid [51].

    A mixture of -amyrin, -amyrin and pomolic acid were isolated from the stems of L. camara [52].

    Three quercetin derivatives named contained 3-methoxy-,

    3, 7-dimethoxy- and 3, 7, 4-trimethoxyquercetin were also separated from L. camara [53]. A novel triterpene,

    22-acetoxylantic acid and the known triterpenes lantic acid and lantanolic acid were also isolated from L.

    camara [54].

    Geniposide, the biosynthetic precursor of

    theveside, has been isolated from the roots of L. camara,

    together with 8-epiloganin, shanzhside methyl ester and

    lamiridoside. Six oligosaccharides, ajugose, stachyose,

    verbascotetraose, verbascose, lantanose A and B and

    flavone named camaroside were isolated from the roots of

    L. camara [55].

    Lantadene C has been isolated from the leaves of

    the hepatotoxic plant L. camara was identical with

    dihydrolantadene A. The molecular structure of lantadene

    C has been deduced from single crystal X ray diffraction

  • Inter. J. of Phytotherapy / Vol 2 / Issue 2 / 2012 / 66-73.

    ~ 69 ~

    analysis. It resembles lantadene A in the pentacyclic

    portion of the molecule but differs in the side chain

    region. Atom C-34 is cis to C-35 in lantadene C but is

    trans in lantadene A [56]. Another pentacyclic triterpene

    named lantabetulic acid was isolated from L. camara [57].

    PHARMACOLOGICAL ACTIVITIES

    Antibacterial activity

    Deepak Ganjewala etal carried out the

    antibacterial activities of leaves and flowers extracts

    obtained with ethyl acetate. The test organisms used in

    this study were Escherichia coli (MTCC901),

    Pseudomonas aeruginosa (MTCC429), Bacillus subtillis

    (1429) and Staphylococcus aureus (MTCC96). Leaf and

    flower ethyl acetate extracts exhibited considerable

    antibacterial activities against the bacteria used where the

    value of zone of inhibition ranged from 10-21 and 9-15

    mm, respectively. For flower and leaf ethyl acetate

    extracts, the zone of inhibition (mm) measured ranged

    from 10-21 and 9-15 mm, respectively. Antibacterial

    activities vary from one L. camara to the other. The

    effectiveness of the extracts varies with its concentration

    and the kind of bacteria used in the study [3]. Mary Kensa

    V has also performed the antibacterial activity of various

    extracts of L. camara. Methanol, Petroleum ether, water

    and Chloroform extracts of leaf, stem and root were tested

    against various pathogenic bacterial species of E.coli,

    Pseudomonas aeruginosa, Staphylococcus aureus and

    staphylococcus saprophiticus by disc diffusion method.

    Leaves were showed strong inhibition compared to stem

    and root extracts on all tested bacterial strains [58].

    Antihelmintic activity

    Successive extracts from the leaves of Lantana

    camara Linn were investigated for their anthelmintic

    activity against Pheretima posthuma and three

    concentrations (10, 50 and 100 mg/ml) of each extracts

    were used in the study. The parameters used to determine

    the activity were determination of time of paralysis and

    time of death of the worm. Ethanolic extract exhibited

    significant anthelmintic activity at highest concentration

    of 100 mg/ml. Piperazine citrate in 10 mg/ml

    concentration was included as standard reference and 1%

    Gum acacia in normal saline as control. The anthelmintic

    activity of ethanol extract was significant followed by

    hydroalcoholic extract of Lantana camara [59].

    Antiulcer activity

    Methanolic extract of Lantana camara was

    evaluated for antiulcerogenic effect in aspirin induced

    gastric ulcerogenesis in pyloric ligated rats, ethanol

    induced gastric ulcer, and cysteamine induced duodenal

    ulcer models. The extract was administered orally at two

    different doses of 250 mg/kg and 500 mg/kg. The lipid

    peroxidation, reduced glutathione levels of ethanol

    induced gastric ulcer model and inhibition zone in

    diameter against Helicobacter pylori also determined. The

    L. camara extract significantly (P < 0.01) reduced ulcer

    index, total acidity and significantly (P < 0.01) increased

    the gastric pH of aspirin + pylorus-ligation induced

    ulcerogenesis and ethanol induced gastric ulcer models.

    The extract also significantly (P < 0.01) reduced the ulcer

    index of cysteamine induced duodenal ulcer. The L.

    camara showed significant (P < 0.01) reduction in lipid

    peroxidation and increase in reduced glutathione levels.

    The methanolic extract of Lantana camara leaves shown

    healing of gastric ulcers and also prevents development of

    duodenal ulcers in rats [14].

    Termiticidal activity

    Extracts of Lantana camara var. aculeata leaves

    were studied for their termiticidal effects against adult

    termite workers. The 5% chloroform extract was found to

    be significantly effective against termite workers [20].

    Wound healing activity

    Burn wound healing activity of the ethanol leaf

    extract of L.camara was carried out in Sprague dawley

    rats. Healing was assessed by the rate of wound

    contraction and period of epithelialization. Extract treated

    wounds were healed in about 21 days which is not distinct

    from the controls. The data suggested that L. camara has

    no wound healing promoting activity on burn wound [60].

    Nayak etal.,has performed the wound healing activity of

    the aqueous extract of L. camara and the extract showed

    significant activity in excision wound model. Wound

    healing time, wound contraction and synthesis of collagen

    were considered as the major parameters to evaluate the

    wound healing activity. [61]

    Anticancer activity

    Pet ether, chloroform, ethanol and aqueous

    extracts of Lantana camara were screened for preliminary

    anticancer activity by using antimitotic activity. Ethanol

    extract exhibited better antimitotic activity as reduction in

    mitotic index was observed from 90.2 % to 61.4 % and

    from 97.6 % to 49.4 % after 1 and 3 hour treatment of

    extract having concentration of 10 mg/ ml. Mitotic index

    of all the extracts treated roots were significantly lower

    than the mitotic index of control. Mitotic index of

    methotrexate was found to be 57.0 % and 55.8 % after 1

    and 3 hour treatment respectively [62].

    Effect on red blood cells

    The effects of an aqueous extract of Lantana

    camara on the osmotic fragility and on the morphology of

    RBC were carried out. In the presence of the extract, the

    data obtained indicated a significant (p < 0.05) increase of

    hemolysis and modifications on the morphology of RBC.

    These effects of the Lantana camara may be associated

    with some pharmacological properties of the chemical

    compounds of aqueous extract [63].

    Antimotility activity

    Evaluation of antimotility activity was done in

    intestine of mice treated with Lantana camara leaf

    powder, Lantana camara methanol extract (LCME),

    lantadene A, neostigmine and neostigmine + LCME.

    Neostigmine was used as a promotility agent. Intestinal

    motility was assessed by charcoal meal test and

    gastrointestinal transit rate was expressed as the

    percentage of the distance traversed by the charcoal

    divided by the total length of the small intestine. The

    intestinal transit with LCME at a dose of 500 mg/kg was

    26.46% whereas the higher dose (1g/kg) completely

    inhibited the transit of charcoal in normal mice. The %

    intestinal transit in the neostigmine pretreated groups was

    24 and 11 at the same doses respectively. When the plant

    extracts at 125 and 250 mg/kg doses were administered

    intraperitonealy, there was significant reduction in fecal

    output compared with castor oil treated mice. At higher

    doses (500 and 1000 mg/kg), the fecal output was almost

    completely stopped [64].

    Cytotoxicity and antitubercular activity

    The Antitubercular activity of Lantana camara

    on multiple-drug-resistant Mycobacterium was

    investigated among Nigerian HIV-infected-persons.

    Minimal inhibitory concentration (MIC) was estimated by

    the well-in-agar-diffusion method and potency of extracts

    compared with standard drugs. Cytotoxicity was

    determined using brine shrimps. MIC of drugs was

    0.33mg/ml, 0.25mg/ml and 0.20mg/ml for streptomycin,

    isoniazide and rifampicin. L. camara had MIC of

    0.63mg/ml for M. tuberculosis and unidentified M. avium

    complex and 0.89mg/ml for M. avium complex. LC50 of

    L. camara had 32.6ppm for M. tuberculosis, 55.9ppm for

    M. avium complex and 51.3ppm for unidentified species.

    The observed activity of the extracts is consistent with

    their use in traditional medicine for the treatment of

    Mycobacterium species [65].

    Anti hyperglycemic Activity:

    Methanol extract of Lantana camara Linn fruits

    were orally tested at the dose of 100 and 200 mg/kg for

    hypoglycemic activity for normal and streptozotocin

    induced diabetic rats. Methanol extract of Lantana

    camara Linn fruit 200 mg/kg produced a significant

    reduction in fasting blood glucose level in the normal and

    streptozotocin induced diabetic rats [66].

    Effect on general reproductive performance and

    teratology

    Effects of hydroalcoholic extract from Lantana

    camara var. aculeata leaves on fertility, general

    reproductive performance and teratology in the rat were

    reported. The data showed that the extract interfered in

    the frequency of fetal skeleton anomalies from dams

    treated with the extract and induced embryotoxicity as

    indicated by post-implantation loss, without any signs of

    maternal toxicity [7].

    CONCLUSION

    Demand to herbal drugs is increasing day by

    day. Plants contain number of chemical moieties with

    varied pharmacological activities. Many potent and

    efficous medicinal principles used for treating dreadful

    diseases have been isolated from plant kingdom. So it is

    very clear that the study of the medicinal plants is

    important to meet the requirements in effective therapy.

    Lantana camara is considered as weed used in folk

    medicine in many parts of the world. Phytochemical

    studies showed that the plant is free from diterpenoids and

    rich in essential oils. Monoterpenes, triterpenes, flavones

    coumarin, steroids, iridoid glycosides, are reported from

    Lantana camara. Triterpenes and flavones are the more

    common secondary metabolites in Lantana camara. Most

    of the pharmacological studies were preliminary, carried

    out in animals and are not sufficient for the development

    of a pharmaceutical product. Still, intensive preclinical

    and clinical studies are required to evaluate the efficacy

    and toxicity of these plant products.
