摘要: 从甘肃产的猫儿屎(Decaisnea Fargesi)植物茎中分离出三个新皂甙.利用二维核磁共振(2DNMR)技术研究确定了它们的化学结构,并对其进行了13C和1H的全归属.

Abstract: Three new triterpenoid glycosides were isolated from the stems of Decaisnea forgesii used as an antitheumatic and antitussive drug for a long time in Chinese folk medicine. Their structures were determined on basis of chemical method, FABMS, homonuclear and het-eronuclear correlation experiments including 1H-1H COSY, 1H-13C COSY, TOCSY and NOESY techniques. All of the 1H and 13C NMR chemical shifts of the three new triterpenoid glycosides were assigned for the first time.

Key words: Decaisnea fargesii, Triterpenoid glycoside, 2D NMR
