天山假狼毒的化学成分研究

目的研究天山假狼毒Stelleropsis tianschanica地上部位的化学成分。方法采用多种柱色谱技术进行分离纯化,通过波谱技术结合化学方法进行结构鉴定。结果从天山假狼毒甲醇提取物中分离得到了13个化合物,分别鉴定为(+)-松脂酚(1)、(-)-松脂酚(2)、3′-desmethylarctigenin(3)、牛蒡子苷元(4)、pluviatolide(5)、伞形花内酯(6)、4-(3,4-dimethoxybenzyl)-3-(4-hydroxy-3-methoxybenzyl)-tetrahydrofuran-2-ol(7)、daphnogitin(8)、daphnetone(9)、blumenol B(10)、loliolide(11)、对羟基苯乙酮(12)、对羟基苯丙酸(13);其中包括7个木脂素类、2个香豆素类化合物。结论化合物1~13均为首次从该属植物中分离得到。

Chemical constituents from plant of Stelleropsis tianschanica

Objective To study the chemical constituents from the arerial parts of Stelleropsis tianschanica. Methods The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were identified by spectra analysis and chemical methods. Results Thirteen compounds were isolated from S. tianschanica and the structures were identified as (+)-pinoresinol (1), (-)-pinoresinol (2), 3'-desmethylarctigenin (3), arctigenin (4), pluviatolide (5), umbelliferone (6), 4-(3,4-dimethoxybenzyl)-3-(4-hydroxy-3-methoxybenzyl)-tetrahydrofuran-2-ol (7), daphnogitin (8), daphnetone (9), blumenol B (10), loliolide (11), 4'-hydroxyacetophenone (12), and 4'-hydroxybenzoic acid (13). Conclusion Compounds 1-13 were all obtained for the first time from the plant of S. tianschanica and the genus Stelleropsis Pobed.
