New Triterpenes from Siyekucai (Ixeris chinensis)
摘要:
Three new triterpenes, 3β, 21α-dihydroxylupen-18(19)-en (1), 3β, 25-dihydroxytirucalla7, 23(24)-dien (2), and 21α-hydroxy-19α-hydrogentaraxasterol-20(30)-en (3) were obtained from an ethyl acetate extract of the whole plant of Siyekucai (Ixeris chinensis). The structures of 1-3 were determined by spectroscopic methods (EIMS, IR, 1D and 2D NMR).
