AKTIVITAS MINYAK ATSIRI RIMPANG BENGLE (Zingiber cassumunar Roxb.) TERHADAP PERTUMBUHAN MALASSEZIA FURFUR IN VITRO

Abstract

Background : Public tendency to back to nature product is start to increase. Bengle is nature product of traditional medical plant that its use is not much known. To know one of its use, the research of its essential oil composer component and its activity to Malassezia furfur is done. Method : Essential oil that use in this research take from steam destilation. This essential oil is separated using Thin Layer Chromatography (TLC). It use Silica Gel GF 254 as stasioner fase, Chloroform-Benzene (1:1) as mobile fase, and UV light 254 nm and 365 nm to make spot visible. To know its activity to Malassezia furfur, the experimental research with post test only control group design is done. Its use 5 kind of essential oil concentration that is 100%; 50%; 25%; 12,5%; 6,25% and one control. The media that used is Sabouraud Dextrose Agar(SDA) + olive oil. The incubation is done at 37oC for 2 days. The evaluation is done by see the growth of colonies Malassezia furfur at surface of the media. Result :. The essential oil, obtained by steam destilation, was an clear yellow color, spesific stings aromas and easy to evaporate. The separation result using TLC show 4 spots that can be observe at wave length 254 nm. The result of microbiology research, after get statistic analized using Mann-Whitney test, is all consentration of volatile oil that used have activity to Malassezia furfur significantly different with p=0,003. Conclusion : Four spot of component that visible is probably from terpen group. Essential oil have activity to Malassezia furfur. Lowest concentration that used still have 100% activities.
