摘要：

From the roots of Helicteres angustifolia, collected from Anhui province, two triterpenoids of oleanolic acid type were obtained and were identified as new compounds, methyl 3beta-hydroxyolean-12-en-27-benzoyloxy-28-oate(1) and 3beta-O-(p-hydroxy-(E)-cinnamoyl)-12 oleanen-28-oic acid(2). The variety of spectroscopic methods such as IR, HRMS, EIMS, H-H COSY, H-C COSY NMR have been applied in the structural elucidation of these two compounds.
