Abstract

Bangle (Zingiber purpureum) is one of Indonesia's native plants whose pharmacological activity has not been tested and has potential as a medicine. Screening of pharmacological activity from a purified extract of rhizome bangle is done as an effort in the utilization of Indonesian herbal plants as medicinal plants. The first stage is the optimization of the process of making extract of purified rhizome bangle. Purification of this extract is intended to increase the number of certain secondary metabolites that are responsible for antidislipidemia activity of bangle rhizome. So it is expected to have a greater activity than the crude extract. Therefore, in this research will be optimized the process of making purified extract and screening of secondary metabolite content in each extract so that it will be known active compound contained in purified extract. The bangle rhizome is macerated by using 96% ethanol (polar) and n-hexane (nonpolar) solvents. Fractination of n-hexane and 96% ethanol extracts was carried out using liquid vacuum chromatography method. It starts with making a column and a mobile phase (eluent). The mobile phase used is a hexane: chloroform solvent gradient (9: 1; 8: 2; 7: 3; 6: 4; 5: 5; 4: 6); ethyl acetate 100%. The result shows that in hexane fractions with mobile phase hexane: CHCl3 (9: 1) and hexane fractions with mobile phases hexane: CHCl 3 (8: 2) contain terpenoid compounds. When compared with the literature (Farmakope Herba Indonesia), this terpenoid compound is Terpinen-4-ol.

Keywords: Bangle, purified extract, extraction, fractionation.
