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 3β,15α,16α-trihydroxy-11α,12α-epoxy olean-28,13β-olide (6), 3β,15α,16α-trihydroxy-11-oxo-olean-12-en-28-oic acids (7 and 8), and 3β,15α,16α-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.
从榼藤子的茎中分离出了10种新的三萜皂苷(1 - 10)。通过光谱分析和化学方法阐明了它们的结构。在这些化合物中,本研究首次报道了6 - 10的苷元,包括3β,15α,16α - 三羟基 - 11α,12α - 环氧齐墩果 - 28,13β - 内酯(6)、3β,15α,16α - 三羟基 - 11 - 氧代 - 齐墩果 - 12 - 烯 - 28 - 酸(7和8)以及3β,15α,16α - 三羟基 - 齐墩果 - 11,13(18) - 二烯 - 28 - 酸(9和10)。评估了所有这些化合物对HepG - 2、A549和Ec - 1细胞系的细胞毒性活性。
