摘要
从我国特有植物珙桐(Davidia involucrata Baill.)枝条中得到6个化合物,经化学和光谱分析,分别鉴定为蒲公英萜酮(D_1)、蒲公英萜醇(D_2)、β-谷甾醇(D_3)、3,4-O,O-次甲基-3′-O-甲基鞣花酸(D_4)、3,3′,4-O-三甲基鞣花酸(D_3)、鞣花酸(D_4)。
Six compounds have been isolatea from the branch of Davidia involucrata Baill which is native to China.Their structures were identified as taraxerone(D_1),taraxerol(D_2),β-sitoste- rol(D_3),3'-O-methyl-3,4-O,O-methylideneellagic acid(D_4),3,3',4-5-trimethylellagic acid (D_5)and ellagic acid(D_6)by means of chemical methods and IR ~1H-NMR,MS,respect(?)vely.
