桃儿七中酚类成分研究

目的研究桃儿七Sinopodophyllum emodi的酚类成分。方法通过多种色谱方法进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果从桃儿七中分离得到10个化合物,分别鉴定为对羟基苯甲醛(1)、原儿茶酸(2)、4-羟基-3-甲氧基苯乙酮(3)、香草酸(4)、香草酸-4-O-β-D-葡萄糖苷(5)、ilexpubside A(6)、对羟基苯乙醇(7)、苯乙醇-4-O-β-D-木糖基-(1→6)-β-D-葡萄糖苷(8)、2-(4′-羟苯基)-硝基乙烷(9)、2-(4′-羟苯基)-硝基乙烷-4′-O-β-D-木糖基-(1→6)-β-D-葡萄糖苷(10)。结论化合物1～6、9、10为首次从该属植物中分离得到。

Phenols from roots and rhizomes of Sinopodophyllum emodi

Objective To study phenols in roots and rhizomes of Sinopodophyllum emodi.Methods The obtained compounds were isolated by different chromatographic methods and their structures were identified by physicochemical properties and spectral data.Results Ten compounds were isolated and identified as 4-hydroxybenzaldehyde(1),protocatechuic acid(2),1-(4-hydroxy-3methoxyphenyl) ethanone(3),vanillic acid(4),vanillic acid-4-O-β-D-glucoside(5),ilexpubside A(6),tyrosol(7),phenyl ethanol4-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside(8),2-(4′-hydroxyphenyl)-1-nitroethane(9),and 2-(4′-hydroxyphenyl)nitroethane-4′-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside(10).Conclusion Compounds 1—6,9,and 10 are obtained from plants in Sinopodophyllum Ying for the first time.
