CHARACTERIZATION OF ANTIFUNGAL ACTIVITY OF THE VARIOUS ACTIVE CONSTITUENTS OF COLEUS
- Antifungal, active constituents, Coleus forskohlii.
The aim of this study was to evaluate the anti-fungal effect of different solvent extracts of Coleus forskohlii which contains minor diterpenoids, deacetylforskohlin, 9-deoxyforskohlin, 1,9-deoxyforskohlin, 1,9-dideoxy-7-deacetylforskohlin, and four other diterpenoids, along with alkaloids and volatile oils. The solvent extracts included both polarized and non-polarized solvents like methanol, ethylacetate, benzene, chloroform, water, hexane, acetone and ethanol. As a result of this study, the antifungal effect was best observed with the methanolic extract against Candida albicans in comparison to the other extracts. This study also revealed that apart from forskohlin, which was confirmed by Thin Layer Chromatography, other compounds that were extracted with methanol are required to produce the antifungal effect and can be taken forward to pharmaceutical preparations.
