Congmujingnosides B-G, triterpene saponins from the stem of Aralia chinensis and their protective effects against H2O2-induced myocardial cell injury.
Wen Zhang,Zhu Nailiang,Meigeng Hu,Shichun Yu,Zhong-Hao Sun,Haifeng Wu,Peng-Fei Li,Jun-Shan Yang,Guo-Xu Ma,Xudong Xu +9 more
TL;DR: Phytochemical investigation of the stem of Aralia chinensis yielded six new oleanane-type triterpene saponins named as congmujingnosides B-G (1–6), which were elucidated on the basis of the chemical and spectroscopic analysis.
Journal ArticleDOI
New polyoxypregnane glycosides from Aspidopterys obcordata vines with antitumor activity
Meigeng Hu,Yihang Li,Zhaocui Sun,Xiaowei Huo,Zhu Nailiang,Zhong-Hao Sun,Yang-Yang Liu,Haifeng Wu,Xudong Xu,Guo-Xu Ma,Guang Li +10 more
TL;DR: Flow cytometry experiments showed that the effects of compound 1 on the cell cycle were attributable to cell cycle arrest at G1/S phase, and compounds 1-6 and 9 showed selective cytotoxicity against HuH-7 cells with IC50 values of 8.7 and 7.4 μM, respectively.
Journal ArticleDOI
A new steroidal saponin from Polygonatum sibiricum
TL;DR: A new furostan type steroidal saponin, kingianoside Z, along with four known compounds, was isolated from the ethanolic extract of Polygonatum sibiricum Delar and showed significant cytotoxicity against HepG2 cell lines.
