Abstract

From Podocarpus imbricatus five compounds were isolated and identified as 2"-O-rhamnosylvitexin (I), hinokiflavone (II), ecdysterone (III), beta-sitosteryl heptadecoate (IV) and daucosterol(V) on the basis of spectral studies (UV, IR, 1HNMR, 13CNMR, MS) and chemical reactions. I, II, III, IV are obtained from this plant for the first time, and IV is obtained as beta-sitosteryl odd number carboxylic ester for the first time.
