兴安柴胡化学成分研究(Ⅰ)

Studies on the Chemical Constituents of Bupleurum Sibiricum Vest

本文报道在兴安柴胡中分得七种酸性成分和四种黄酮类物质,经光谱分析和化学方法,鉴定为棕榈酸(Ⅰ),硬酯酸(Ⅱ)、香草酸(Ⅲ)、延胡索酸(Ⅳ)、咖徘酸(Ⅴ)、对苯二甲酸(Ⅵ)、阿魏酸(Ⅷ)槲皮素(疆)、山萘素(Ⅸ)、槲皮素—3—0—α—L—鼠李糖甙(Ⅹ)、芦丁(Ⅺ).

The methanolic extract of roots of Bupleurum Sibiricum Vest wasseparated by repeated chromatographies(Si Gel;Al_2O_3;polyamide;Sphadex LH-20 columns).On the basis of spectroscopic analyses(IR,EIMS,~1H and ^(13)CNMR)and chemical methods,eleven compounds wereidentified as:palmitic acid(Ⅰ),stearic acid(Ⅱ),vanillic acid(Ⅲ),fumaric acid (Ⅳ),caffic acid(V),p-benzene diearbonic acid(Ⅵ),ferulic acid(Ⅶ),quercetin(Ⅷ),kaempferol(Ⅸ),quercetin-3-0-α-L-rhamnoside(X),rutin(Ⅺ),Compounds Ⅲ,Ⅳ,Ⅵ,Ⅴ,Ⅶ were foundin this genus for the first time.
