Triterpenoids from plants of the genus Tamarix

摘要

The taraxeran-14-ene-type triterpenoids methyl 3-beta-al-D-fridoolean-14-en-28-oate (1), 3-alpha-[3",4'-dihydroxy-trans-cinnamoyl]-oxy-D-fridoolean-14-en-28-oic acid (2), and P-sitosterol (3) were isolated from the aerial part of plants from the genus Tamarix (T. laxa, T. elongata) (Tamaricaceae). The structures of the triterpenoids were proved using spectral data (IR, UV, PMR, C-13 NMR, 2D NMR H-1-H-1 COSY, HMQC, HMBC, mass). Compound 1 is new and not previously described in the literature.
