摘　　要：从甘肃产的猫儿屎（ＤｅｃａｉｓｎｅａＦａｒｇｅｓｉ）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。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 heteronuclear correlation experiments including 1H 1H COSY, 1H 13 C COSY, TOCSY and NOESY techniques. All of the 1H and 13 C NMR chemical shifts of the three new triterpenoid glycosides were assigned for the first time.
