穿鞘菝葜的化学成分

从穿鞘菝葜(Smilax perfoliata Lour.)的95%乙醇提取物的乙酸乙酯萃取部分分离得到6个化合物,其中有一个新化合物smilglaside F(1).经过核磁共振、质谱、红外光谱及化学手段鉴定了它们的结构.5个已知化合物分别是:芦丁(2)、3′-甲醚芦丁(3)、cassiamin A(4)、cassiamin B(5)和1,2,3-trimethoxy-5-hydroxyphenol-1-O-β-D-glucopyranoside(6).其中化合物2、4～6是首次从该属植物分离得到.

Chemical Constituents of Smilax perfoliata

One new compound named smilglaside F (1) and five known ones (2-6) were isolated from the EtOAc portion of the 95% ethanolic extract of Smilax perfoliata Lour. by silica gel and ODS column chromatography. On the basis of chemical and spectral methods, they were identified as 1, 6-O-diferuloyl-(3-O-p-coumaroyl)-b-D-fructofuranosyl-(2→1)-2-O-acetyl-a-D-glucopyranoside (1), rutin (2), narcissin (3), cassiamin A (4), cassiamin B (5) and 1, 2, 3-trimethoxy-5-hydroxyphenol-1-O-b-D-glucopyranoside (6), respectivety. Compounds 1, 3-6 were obtained from the genus Smilax for the first time.
