Two triterpene acetates (V and I) were isolated from the leaves of Quercus gilva BLUME. V was obtained as a new compound from natural source. Its structure was determined as 24, 24-dimethyllanosta-9(11)-dien-3β-yl acetate by the physicochemical methods and chemical evidence. I was established as hop-17(21)-en-3β-yl acetate, which was previously obtained from Quercus spp.
