鞘柄菝葜化学成分研究

Studies on Chemical Constituents of Rhizome of Sheathstipe Greenbrier (Smilax stans)

从鞘柄菝葜SmilaxstansMaxim．根中首次分得9个化合物。经理化常数、光谱分析及与标准样品对照，鉴定为木栓酮（friedelin），薯蓣皂甙元（diosgenin），3，5，4’-三羟基（3，5，4’－trihydroxylstilbene），3，5，3’，4’-四羟基芪（3，5，3’，4’－tetrahydroxylstilbene），正丁基-O-β-D-果糖甙（n－butanol－O-β-D-fructopyranoside），葫萝卜甙（sitosterol－3-O-β-D－glucoside），薯蓣皂甙（dioscin），甲基原薯蓣皂甙（methylprotodio－scin）和伪原薯蓣皂甙（pseudoprotodioscin）。

From the rhizome of Smilax stans Maxim., nine compounds were isolated and their structures were determined to be friedelin, diosgenin, 3, 5, 4'-trihydroxy stilbene, 3, 5, 3',4' -tetrahydroxy stilbene, n-butanol- O-β- D-fructopyranoside, sitosterol-3-O-β- D-glucoside,dioscin, methyl protodioscin and pseudo protodioscin on the basis of chemical,spectral methods and comparison with authentic samples.
