LC-MS guided chemical investigation of the periploside-rich extract of the root barks of Periploca sepium afforded six new minor pregnane glycosides, named periplosides A1-A6 (1-6). Their structures were characterized on the basis of extensive spectroscopic analysis. Compounds 1-6 were evaluated for their inhibitory activities against the proliferation of T and B lymphocytes in vitro, among them, compound 5 exhibited significant inhibitory activities and the most favorite selective index (SI) values against the proliferation of T lymphocyte (IC = 0.30 μM, SI = 176) and B lymphocyte (IC = 0.55 μM, SI = 97).
LC-MS 引导的对杠柳根皮中富含杠柳苷的提取物的化学成分研究,得到了六个新的孕烷糖苷类化合物,命名为杠柳苷 A1-A6(1-6)。它们的结构是基于广泛的光谱分析来确定的。对化合物 1-6 进行了体外抑制 T 和 B 淋巴细胞增殖活性的评价,其中,化合物 5 对 T 淋巴细胞(IC=0.30μM,SI=176)和 B 淋巴细胞(IC=0.55μM,SI=97)的增殖具有显著的抑制活性和最理想的选择性指数(SI)值。
