青钱柳叶的化学成分研究

Chemical Constituents from the Leaves of Cyclocarya paliurus

摘要:

为了解青钱柳（Cyclocarya paliurus）叶中的化学成分，从其叶的95%乙醇提取物中分离得到了12个化合物。经波谱分析分别鉴定为：姜酮（1）、咖啡酸甲脂（2）、柚皮素（3）、阿江榄仁酸（4）、1-氧代-3β，23-二羟基齐墩果酸（5）、2α-羟基熊果酸（6）、山柰酚（7）、槲皮素（8）、山柰酚-3-O-（3-O-乙酰基-α-l-吡喃鼠李糖苷）（9）、木犀草素（10）、1-氧代-3β，23-二羟基齐墩果酸-28-O-β-d-吡喃葡萄糖苷（11）、阿福豆苷（12）。化合物1、2、5、9和11为首次从青钱柳中分离得到。

Abstract:

In order to understand the chemical constituents of Cyclocarya paliurus, twelve compounds were isolated from the 95% ethanol extract of its leaves. On the basis of spectral data, they were identified as zingerone (1), caffeic acid methyl ester (2), naringenin (3), arjunolic acid (4), 1-oxo-3β,23-dihydroxyolean-12-en-28-oic acid (5), 2α-hydroxyursolic acid (6), kaempferol (7), quercetin (8), kaempferol-3-O-(3-O-acetyl-α-l-rhamnopyranoside) (9), luteolin (10), 1-oxo-3β,23-dihydroxyolean-12-en-28-oic acid 28-O-β-d-glucopyranoside (11) and afzelin (12). Compounds 1, 2, 5, 9 and 11 were obtained from this plant species for the first time.
