Abstract: Two new iridoid glycosides, scrospioside A and B along with known harpagoside and p-methoxycinnamic acid were isolated from the roots of Scrophularia spicata Fr., a Zang (Tibetan) nationality's folk medicinal plant in Yunnan. By the spectral data, their structures were elucidated as 6-0-α-L-[2,4-diacetyl-3-trans-cinnamoyl]-rhamnopyranosyl catalpol and 6-0-α-L-[2-acetyl-3-trans-cinnamoyl]-rhamnopyranosyl catalpol, respectively.

摘要： 从云南藏族民间药用植物穗花玄参(Scrophularia spicata Fr．)的根中分离得到3个环烯醚萜配糖体，经光谱分析，其中两个新化合物的结构为6-O-α-L-[2,4-二乙酰基-3-反式肉桂酰基]-鼠李吡喃糖基榨醇和6—O-α-L-[2-乙酰基-3-反式肉桂酰基]-鼠李吡喃糖基梓醇，分别命名为穗花玄参甙(scrospioside)A和B。另一个为已知的哈巴俄甙(harpagoside)，同时还分离到少量的对甲氧基肉桂酸。
