摘要
防己叶菝葜为百合科菝葜属植物(Smilax menispermoides D.C.),分布在我国西北,西南地区,民间用于祛风除湿代替中药土伏苓(S.China Raxb)。迄今未见其化学成分的报道,本文报道防己叶菝葜中一个新的甾体皂甙1的结构鉴定。 1经过Liebermann-Burchard反应和Molish反应示其为一甾体甙,MS(FAB)
A new steroidal saponin, m. p. 310℃, [a]20D= -90. 0℃, was isolated from 70% alcoholic crude saponin extract of the rhizome of Smilax menispermoides D. C. by silica gel column chromatogra-phy and further purified by Sephadex LH-20. Its structure was determined as : (25D) spirost-5-en-3β, 17α,27-triol-3-O-[β-L-rhamnopyranosyl (1-2)] [a-L-rhamnopyranosyl (1-4)]-α-D-glucopyra-noside by means of IR, MS, 13C NMR, DEPT and chemical methods.
