摘要
Ten new triterpene saponins (1-10) have been isolated from the stems of Entada phaseoloides. Their structures were elucidated by spectroscopic analysis and chemical methods. Among these compounds, the aglycons of 6-10 are being reported for the first time, in this study, including 3 beta, 15 alpha, 16 alpha-trihydroxy-11 alpha, 12 alpha-epoxy olean-28,13 beta-olide (6), 3 beta, 15 alpha, 16 alpha-trihydroxy-11-oxo-olean-12-en-28-oic acids (7 and 8), and 3 beta, 15 alpha, 16 alpha-trihydroxy-oleana-11,13(18)-dien-28-oic acids (9 and 10). The cytotoxic activities of all of these compounds were evaluated against HepG-2, A549, and Ec-1 cell lines.
