摘要: 自中药槲寄生中分离得到一个新的黄酮甙,经波谱测定及水解试验,确定其结构为鼠李秦素-3-O-β-D-芹糖基(1→2)-6″-(3-羟基-3-甲基戊二酸半酯)葡萄糖甙,命名为槲寄生新甙Ⅶ(viscumneoside Ⅶ).Abstract: From the ethanol extract of Viscum coloratura (Kom.) Nakai, a new flavonoid has been isolated. Based on chemical and spectroscopic analysis, the structure of Ⅶ has been elucidated as rhamnazin-3-0-β-D-apisoyl-(1→2)-6"-O-(3-hydroxy-3-methylglutarate)-glucoside and named Viscumneoside Ⅶ.
