ABSTRACT
The research done analysis of Zerumbone amount in lempuyang gajah (Zingiber zerumbet(L).J.E Smith) rhizome with extraction method and solvent variety. This study aims to know influence extraction method and solvent variety about zerumbone in Zingiber zerumbet rhizome. Spot color, Rf and spectrum for qualitative analysis then Densitometrically use TLC plate silica gel F254 with mobile phase n-Hexane - ethyl acetate (9:1) at maximum absorbance wavelength 259 nm for quantitative analysis. Analysis with variety extraction method according soxhlet, reflux, maceration using methanol and water distillation acquired that reflux have maximum zerumbone content (25,08%) in extract. Analisis with solvent variety according n-Hexane, Ethanol 70%, and Aquadest using reflux method show that n-Hexane have maximum zerumbone content (53,47%) in extract.
