New indole alkaloild from Amsonia sinensis: New indole alkaloild from Amsonia sinensis. Liu, Hongmei; Wu, Bin; Zheng, Qitai; Feng, Xiaozhang (Inst. Mater. Med., Chin. Acad. Med. Sci., Beijing 100050, Peop. Rep. China). Planta Med., 57(6), 566-8 (English) 1991. 50838-11-4 and 3247-10-7 which are cas registry numbers are also used here. CODEN: PLMEAA. ISSN: 0032-0943. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Section cross-reference(s): 31 Fourteen indole alkaloids, D14-isoeburnamine, amsosinine, tabersonine, vincadifformine, lochnericine, tetrahydroalstonine, b-yohimbine, isoburnamine, minovicinine, picrinine, strictamine, rhazimine, vincanidine, and decarbomethoxytetrahydrosecamine, were isolated from A. sinensis. D14-Isoeburnamine (I) and amosisinine (II) are new compds. and their structures were established by spectral and chem. methods. A known sterol glycoside, daucosterol, was also obtained. The structures of compds. I and II were finally confirmed by x-ray diffraction of single crystals. .
