摘 要:目的:研究白花丹Plumbago zeylanicaLinn.地上部分的化学成分。方法:对白花丹95%乙醇提取物的乙酸乙酯部分进行色谱分离,通过理化性质和波谱分析鉴定化合物的结构。结果:从白花丹中分离得到9个化合物,分别鉴定为白花丹醌(Ⅰ),isoshinanolone(Ⅱ),白花丹酸(Ⅲ),β-谷甾醇(Ⅳ),对羟基苯甲醛(Ⅴ),反式桂皮酸(Ⅵ),香兰子酸(Ⅶ),2,5-二甲基-7-羟基-色原酮(Ⅷ),3-吲哚甲醛(Ⅸ)。结论:化合物Ⅴ,Ⅶ,Ⅷ和Ⅸ为首次从白花丹属植物中分离得到。Objective : To investigate the chemical constituents of the aerial parts of Plumbago zeylanica Linn. Methods : The constituents of the EtOAc-soluble portion in the 95% ethanol extract were isolated and purified by means of chromatography. Compounds were identified by their physical characteristics and spectral features. Results: Nine compounds were isolated as plumbagin ( Ⅰ ) , isoshinanolone ( Ⅱ ) , plumbagic acid ( Ⅲ ) , β-sitosterol ( Ⅳ ) ,4-hydroxybenzaldehyde ( Ⅴ ) , trans-cinnamic acid ( Ⅵ ) , vanillic acid ( Ⅶ ) , 2, 5-dimethyl-7-hydroxychromone ( Ⅷ ) , indole-3-earboxaldehyde ( Ⅸ ). Conclusion : Compounds Ⅴ,Ⅶ,Ⅷ, and Ⅸ were isolated for the first time from Plumbago Linn.
