摘要
目的:对河南济源产冬凌草的化学成分进行研究。方法:运用多种层析手段进行分离纯化,通过波谱解析和理化鉴别进行结构鉴定。结果:分离鉴定了11个化合物,分别为:5,4′-二羟基-6,7,8,3′-四甲氧基黄酮(1),冬凌草乙素(2),rabdokaurin C(3),lasiokaurinol(4),冬凌草甲素(5),lasiodonin(6),香草酸(7),原儿茶醛(8),阿魏酸(9),咖啡酸(10),槲皮素(11)。结论:化合物3、4为首次从冬凌草中分得,化合物1、7、8为首次从香茶菜属中分得。
AIM： To study the chemical constituents of Rabdosia rubescens [ Hemsl, ] Hara. METHODS： The chemical constituents were isolated by various chromatographic methods, and the chemical structures were elucidated on the basis of spectral analysis. RESULTS： Eleven compounds were obtained and their structures were identified as 5,4＇-dihydroxy-6, 7, 8, 3＇-tetramethoxyflavone （1）, ponicidin （2）, rabdokaurin C （3）, lasiokaurinol （4）, oridonin （5）, lasiodonin （6）, vaniUic acid （7）, protocatechuic aldehyde （8）, fendic acid （9）, caffeic acid （10）, quercetin （11）. CONCLUSION： Compounds 3 and 4 were isolated from Rabdosia rubescens [ Hemsl. ] Hara for the first time and compounds 1, 7 and 8 have been isolated from this genus for the first time.
