【摘要】 自兴安胡枝子叶中首次分到9个黄酮甙、一个甙元和一个高级脂肪醇。经光谱和理化分析并与已知文献对照,确定其结构为:异荭草素(isoorlentin,Ⅰ)、香叶木素-7-O-葡萄糖甙(diosmetin-7-O-glucoside,Ⅱ)、异牡荆素(isovitexin,Ⅲ)、异荆牡素-2″-木糖甙(isovitexia-2″-xyloside,Ⅳ)、异鼠李素-3-O-芸香糖甙(isorhamaetin-3-O-rutinside,Ⅴ)、荭草素(Orientin,Ⅵ)、6-C一吡喃葡萄糖基-8-C-吡喃阿拉伯糖芹菜甙(6-C-glucopyranosyl-8-Carabinopyranosylapigenia,Ⅷ)、异荭草素-2″-木糖甙(isoorieutin-2″-xyloside,Ⅷ)、牡荆素(vitexia,Ⅸ)、槲皮素(甙元,ⅹ)和1-triacontanol(高级脂肪醇)。其中Ⅱ、Ⅳ和Ⅶ为首次从胡枝子属中发现。更多还原
