Minor terpenoids from the stems and twigs of .

Four minor undescribed terpenoids, including a monoterpenoid () and three triterpenoids (, and ), together with 26 known terpenoids were isolated from the stems and twigs of . Their structures were identified by extensive spectroscopic analyses and electronic circular dichroism (ECD) techniques. Compound showed excellent cytotoxicity against human colon cancer cell (HCT-116) with IC value of 2.56 μM. Compounds and exhibited partly inhibitory effects on nitric oxide production stimulated by lipopolysaccharide-induced neuroinflammation in microglia cells at 10 μM with inhibition ratios of 39.70% and 28.08%, respectively.
