目的:对民间药材石油菜的化学成分进行研究。方法:用硅胶、葡聚糖凝胶Sephadex LH-20等手段进行分离纯化,并通过1H,13C-NMR,MS等波谱方法鉴定结构。结果:分离鉴定了17个化合物,其中酚酸类6个,分别为苯甲酸(benzoicacid,1),对羟基苯甲醛(4-hydroxy benzaldehyde,2),香豆酸(coumaric acid,3),原儿茶酸(protocatechuic acid,4),没食子酸(gal-lic acid,5),对羟基苯甲酸(4-hydroxy benzoic acid,6);含N化合物6个,分别为3-吲哚甲醛(3-indole carboxaldehyde,7),3-吲哚甲酸(3-indole carboxylic acid,8),4-甲基-(1,2,3)-三唑[4-methyl-(1,2,3)-triazole,9],尿嘧啶(uracil,10),菸酰胺(nicotinam-ide,11),(2S,E)-N-[2-羟基-2-(4-羟基苯)乙酯]阿魏酰胺{(2S,E)-N-[2-Hydroxy-2-(4-hydroxyphenyl)ethyl]ferulamide,12};5个其他类成分,(+)-去氢催吐萝芙醇[(+)-dehydrovomifoliol,13],正三十一烷(hentriantane,14),β-谷甾醇(β-sitosterol,15),棕榈酸(palmitic acid,16),胡萝卜苷(daucossterol,17)。结论:所有化合物均为首次从该属植物中分离得到。 Objective: To study the chemical constituents of folk medicinal rapeseed. Methods: Sephadex LH-20 was purified by silica gel and Sephadex LH-20, and identified by 1H, 13C-NMR and MS spectroscopy. Results: Seventeen compounds were isolated and identified, of which 6 phenolic acids were benzoic acid (1), 4-hydroxy benzaldehyde (2), coumaric acid (3) Protocatechuic acid (4), gal-lic acid (5), and 4-hydroxybenzoic acid (6) -indole carboxaldehyde, 7), 3-indole carboxylic acid (8), 4-methyl- triazole 9, uracil 10, nicotinam-ide 11, (2S, E) -N- [2-hydroxy-2- (+) - dehydrovomifoliol [(+) - dehydrovomifoliol (+) - dehydrovomifoliol , 13], hentriantane (14), β-sitosterol (15), palmitic acid (16), daucossterol (17). Conclusion: All the compounds were isolated from this genus for the first time.
