An extensive investigation of the so-called jalapin resinoid obtained from roots of the Mexican scammony, Ipomoea orizabensis, using high field NMR spectroscopy led to the characterization of six glycosides, including the known scammonins I (1) and II (2) and four new tetrasaccharides of jalapinolic acid, orizabins V-VIII (3-6). All the isolates (1-6) were found to be weakly cytotoxic toward human oral epidermoid carcinoma (KB).
利用高场核磁共振光谱对从墨西哥泻根(Ipomoea orizabensis)根部获得的所谓药喇叭树脂进行了广泛研究,鉴定出六种糖苷,包括已知的药喇叭皂苷I(1)和II(2)以及四种新的药喇叭油酸四糖,即奥里萨宾V - VIII(3 - 6)。发现所有分离物(1 - 6)对人口腔表皮样癌(KB)具有弱细胞毒性。
