水杨梅根的化学成分

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。
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
