Abstract: MoutaiDistiller yeast were extracted by 75% ethanol.The purification of the extracts were conducted via various methods including normalphase silica gel column chromatography,reversedphase silica gel column chromatography,Sephadex LH20 gel column chromatography,thin layer chromatography and recrystallization.Seven compounds were isolated and identified from MoutaiDistiller yeast,namely,palmitic acid (1),βsitosterol (2),syringic acid(3),4hydroxybenzoic acid (4),ursolic acid (5),lauric acid (6) and Vanillin (7).It is the first time in history to isolate and identify the compounds mentioned above from the MoutaiDistiller yeast.
