Abstract: In clinical, Psychotria serpens L. was often substitute for Caulis trachelospermi to treat cancer in China. Meanwhile, EtOAc and n-BuOH fractions of MeOH extract of P. serpens L. show power activity against H460, HepG2, Hela, and PC9/GR cell lines, and no toxic effects against normal 16HBE cell lines. In order to search significant anti-cancer active leading compounds, sevenetin (5),rutin (6),kaempferol-3- flavonoids, quercetin(1),tamarixetin-3-O-rutinoside (2),quercetin 3-O-(2^G-β-D- xylopyranosy- lrutinoside) (3), kaempferol(4), tamarixO- rutino- side (7) were isolated from P. serpens L., and their structures were identified through spectroscopic techniques including NMR (1D and 2D) and MS. 2-5 were the first isolated from genus Psychotria.
