What is the aim of my project ? What is Antioxidant? What is Indian propolis? History of indian propolis ? Source of propolis in different geogrhaphical region in india ? Characteristics of propolis ? What the chemical constituents of Indian propolis? Structure of Active constituents of indian propolis? Difference between two active component of indian propolis? What is the advantages of Indian propolis? What is Use of Indian propolis?
WHAT IS THE AIM OF MY PROJET : Study Antioxidant activity of indian propolis and
its chemical constituent and pharmacological effect .
WHAT IS ANTIOXIDANT? An antioxidant is a molecule that inhibit oxidation of
other molecules. Oxidation is a chemical reaction involve loss of
electrons or increase oxidation state . In cellular system oxidation is a natural process. free radicals are generated which prompts chain
reactions. chain reactions cause cellular damage. eventually cause cell death or diseases .
WHAT IS ANTIOXIDANT?. Antioxidant terminated these chain reaction by
involving free radical intermediate , inhibit oxidation .
WHAT IS INDIAN PROPOLIS?
Propolis is a natural resinous mixture produced by honeybees from substances collected from parts of plants. Propolis, also known as ‘bee glue’, is the most important and interesting ‘chemical weapon’ of honey bees.

WHAT IS INDIAN PROPOLIS?
Propolis is having a composition more than 300 phytocompounds . Etymologically the word propolis derived from the Greek pro (for ‘in front of’, ‘at the entrance to’) and polis (for ‘community’ or ‘city’), meaning that this natural product is used for hive defense. Another name of propolis is bee glue. Nowadays, propolis is a natural remedy found in many health food stores in different forms for topical use.
HISTORY OF INDIAN PROPOLISPropolis has a long history of medicinal use, many
years back to 350 B.C., the time of Aristotle. Greeks have used propolis for ulcer disease ; Assyrians have used it for healing wounds and tumors; and Egyptians have used it for mummification. It still has many medicinal uses today, although its effectiveness has only been shown for a couple of them.

DIFFERENT GEOGRHAPHICAL REGION
Propolis composition varies according to different geographical region. Difference shows due to
climate and temperature variati in india.

CHARACTERISTICS OF PROPOLIS Propolis is lipophilic in nature, Hard and brittle material when cold. when temperature rises it becomes soft. It is flexible, gummy and very sticky. It possesses a characteristic and pleasant aromatic
smell and varies in color from yellow green, to red ,black and to dark brown depending on its source .
MELTING POINT :
At temperatures of 25°C to 45°C propolis is a soft, flexible and very sticky substance. Particularly when frozen or at near freezing, it becomes hard and brittle. It will remain brittle after such treatmengt even at higher temperatures. Above 45°C it will become increasingly sticky and gummy. Propolis will become liquid at 60°C to 70°C, but for some samples the melting point may be as high as 100°C.
SOLUBILITY OF PROPOLIS
The most common solvents used for commercial extraction are as follows water, methanol, ethanol, chloroform, dichloromethane, ether, and acetone. Many of the bactericidal components are soluble in water or alcohol. These solvents remove the inert material and preserve the desired compounds.

ADVANTAGES OF INDIAN PROPOLIS: Over the last few decades, worldwide increase in
the use of natural products for pharmacological purposes has been observed.
1) Nowadays, propolis is a natural remedy found in many health food stores in different forms for topical use.
2)It is also used in cosmetics or as popular alternative medicine for self-treatment of various diseases.
3) Current applications of propolis include formulations for cold syndrome.
4) As well as dermatological preparations useful in wound healing, treatment of burns neurodermatitis.
5) Additionally, propolis is used in mouthwashes and toothpastes.
6) It is widely used in cosmetics and in health foods and beverages.
7) It is commercially available in the form of capsules (either pure or in extracts), mouthwash solutions (combined with lemon balm, sage, mallow), creams, throat lozenges, powder and also in many purified products from which the wax was removed .
8) it is widely used in human and veterinary medicine, pharmacology and cosmetics.
USE OF INDIAN PROPOLIS Propolis has been used in traditional medicines for
thousands of years.
Antimicrobial: Preliminary scientific studies show some types of
propolis have in vitro antimicrobial activity with active constituents including flavonoid like galangin and hydrocinamic acids like caffic acid.
ANTI-VIRAL ACTIVITY Viral entry of HIV-1 was inhibited in CD4 lymphocytes. Effectiveness of the reverse transcriptase inhibitor,
zidovudine, was increased.

(Gekker, Hu, Spivak, Lokensgard, & Peterson, 2005)
USE : IT has anti cancer activity It has antifungal activity . It is also used in cosmetics. Current applications of propolis include
formulations for cold syndrome.
USE: In food:.. Propolis is used by some chewing gum
manufacturers to make propolis gum.
Car wax: Propolis is used to bring about a chemical reaction
to convert fats and oils into automobile wax during application.
