Glycosmis parviflora (Sims) Little is used in Vietnamese ethnomedicine to treat several ailments. We investigated the aerial parts of G. parviflora and obtained three triterpenes, a sesquiterpene, and a flavonoid C-glycoside. The terpenes were friedelin, arborinol, isoarborinol, and spathulenol, and the glycoside was vitexin. The compounds were identified by one- and two-dimensional nuclear magnetic resonance spectroscopy and by comparison with previous reports. Spathulenol exhibited moderate cytotoxic activity against LU-1, MDA-MB-231, MKN7, HepG2, and HeLa human cancer cells with 50% inhibitory concentration (IC50) values ranging from 31.88 to 42.33 µg/mL. Therefore, G. parviflora and spathulenol might be useful for developing novel anticancer agents.
