To isolate the chemical constituents from the leaves and stems of Etlingera brevilabrum, the plant parts were firstly extracted by n-hexane. Then the extracts were purified using different chromatography methods such as vacuum liquid chromatography, column chromatography, and preparative thin layer chromatography. Finally tow compounds were isolated from the extracts. To elucidate the structures, the spectroscopic data of the compounds were compared with the literature values. According to the analysis the pure compounds were identified as β- sitosterol and stigmasterol.
