Structure elucidation of the compounds was succeeded by extensive spectroscopic analysis. Twelve compounds were obtained from this plant for the first time, among which six compounds were obtained from the genus Uncaria for the first time.展开更多

The results indicated that ursolic acid showed the strongest activity of inhibiting the proliferation of tumor cells; 3β-6β-23-trihydroxyurs-12-en-28-oic acid, β-sitosterol and 3β-6β-19α-trihydroxyurs-12-en-28-oic acid possessed the same activity, too.展开更多
