To continue to study anti-tumour bioactive saponins EtOAc layer from methanol extract of the stem of psychotria sp.,four compounds were obtained by all kinds of column chromatography,such as silica gel,Sephdex LH -20,and ODS.Their structures were characterized by spectroscopy including NMR,MS,GC-MS analyses,and chemical and the physical methods.The result indicated that they were Psychotrianosides G (1),Ardisianosides D (2),β-amyrin (3),and Stigmasterol-3-O-β-D-glycosidase (4).Cyclamiretin A (5)was obtained by acid hydrolysis of 2.Psychotrianosides G (1)was firstly ob-tained as a natural product.The chemical structure of compound (1)was analyzed by 2D NMR firstly. Compounds 1,2,3,4,5 were firstly obtained from genus of psychotria.
