Common Name1-(1-hydroxyethyl)-7-isopropyl-4-methylidene-2-oxo-hexahydro-1h-inden-5-yl 3-methylbutanoate
Description9Alpha-(3-Methylbutanoyloxy)-4S-hydroxy-10(14)-oplopen-3-one belongs to the class of organic compounds known as sesquiterpenoids. These are terpenes with three consecutive isoprene units. 9Alpha-(3-Methylbutanoyloxy)-4S-hydroxy-10(14)-oplopen-3-one is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 9alpha-(3-Methylbutanoyloxy)-4S-hydroxy-10(14)-oplopen-3-one has been detected, but not quantified in, tea. 1-(1-hydroxyethyl)-7-isopropyl-4-methylidene-2-oxo-hexahydro-1h-inden-5-yl 3-methylbutanoate is found in Tussilago farfara. This could make 9alpha-(3-methylbutanoyloxy)-4S-hydroxy-10(14)-oplopen-3-one a potential biomarker for the consumption of these foods.
