水杨梅根的化学成分

Chemical constituents of Adina rubella

摘要

摘要: 采用硅胶、ODS等柱色谱方法对水杨梅Adina rubella的干燥根的化学成分进行分离纯化，通过NMR，MS等波谱技术鉴定化合物结构，分离鉴定了12个化合物。分别为:5，7-二羟基-2-甲基色原酮-7-O-β-D-葡萄糖苷( 1 )，东莨菪苷( 2 )，(+)-lyoniresinol-3a-O-β-D-glucopyranoside( 3 )，(6S，7R，8R)-7a-［(β-D-glucopyranosyl)oxy］ lyoniresinol( 4 )，harman-3-carboxylic acid( 5 )，lyaloside( 6 )，3-oxoquinovid acid( 7 )，齐墩果酸( 8 )，3-acetyl oleanolic acid( 9 )，quinovic acid 3-O-β-D-glucopyranosyl-28-O-β-L-rhamnopyranosyl ester( 10 )，quinovic acid 3-O-β-D-glucopyranosiyl-28-O-β-D-glucopyranosyl ester( 11 )，pyrocincholic acid 3-O-α-L-rhamnopyranosyl-28-［β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl］ ester( 12 )。其中化合物 3 ， 4 ， 6 ， 8~10 均为首次从该植物中分离得到。

Abstract: From the ethanol extract of Adina rubella, twelve compounds were isolated by silica gel and ODS column chromatography. Their structures were identified by spectroscopic analysis as: 5, 7-dihydroxy-2-methylchromone-7-O-β-D-glucopyranoside( 1 ), scopolin( 2 ), (+)-lyoniresinol-3a-O-β-D-glucopyranoside( 3 ), (6S, 7R, 8R)-7a-［(β-D-glucopyranosyl)oxy］ lyoniresinol( 4 ), harman-3-carboxylic acid( 5 ), lyaloside( 6 ), 3-oxoquinovid acid( 7 ), oleanolic acid( 8 ), 3-acetyl oleanolic acid( 9 ), quinovic acid 3-O-β-D-glucopyranosyl-28-O-β-L-rhamnopyranosyl ester( 10 ), quinovic acid 3-O-β-D-glucopyranosiyl-28-O-β-D-glucopyranosyl ester( 11 )and pyrocincholic acid 3-O-α-L-rhamnopyranosyl-28-［β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl］ ester( 12 ). Compounds 3, 4, 6, 8-10 were isolated from this plant for the first time.
