毛白杨化学成分的研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF POPULUS TOMENTOSA CARR

摘要: 从毛白杨(Populus tomentosa Carr.)的叶中分得一个新的黄酮类化合物,鉴定为洋芹素-7-O-(6″-O-p-羟基肉桂酰)-B-D-吡喃葡萄糖甙(Ⅰ),同时还分得四个已知成分分别鉴定为水杨甙(salicin,Ⅱ)、2″-苯甲酰水杨甙(tremulodin,Ⅲ)、特里杨甙(tremulacin,Ⅳ)和胡萝卜甙(dauvasterol,Ⅴ)。

Abstract: Populus tomentosa Carr. a Chinese folk medicine, has been used for treatment of arthritic disease. A new flavonoid, with molecular formula C₃₀H₂₆O₁₂ was isolated from this plant along with four known compounds. They were identified as apigenin-7-O-(6″-O-p-coumaroyl)-β-D-glucopyranoside (Ⅰ), salicin (Ⅱ), tremulodin (Ⅲ), tremulaein (Ⅳ) and daucosterol (Ⅴ) by the use of ¹HNMR, ¹³CNMR and ¹H-¹³C COSY spectroscopy.
