青钱柳地上部分的化学成分研究

Chemical Constituents from the Aerial Parts of Cyclocarya paliurus

从青钱柳Cyclocarya paliurus(Batal)ljinskaja.地上部分分离出14个化合物,通过NMR波谱方法和理化性质考察分别鉴定为山柰酚(1),山柰酚-3-O-α-L-吡喃鼠李糖苷(2),山柰酚-3-O-β-D-吡喃半乳糖苷(3),山柰酚-3-O-β-D-吡喃葡萄糖苷(4),山柰酚-3-O-α-L-(4′′-E-p-香豆酰基)吡喃鼠李糖苷(5),青钱柳酸B(6),阿江榄仁酸(7),2α,3β,23-三羟基-12-烯-28-乌苏酸(8),2α-羟基乌苏酸(9),齐墩果酸(10),槲皮素(11),异槲皮苷(12),β-谷甾醇(13),胡萝卜苷(14)。化合物2、3、5和8为首次从青钱柳属中分离得到。
