对马甲子地上部分的化学成分进行研究,采用反复硅胶、葡聚糖凝胶、ODS以及制备型高效液相色谱技术进行分离纯化。通过质谱和一维、二维核磁共振波谱方法鉴定其结构。从中共分离并鉴定了8个化合物,分别为3D-羟基-27-(3,4-二羟基)羽扇豆-20(29)-烯-28-酸(1),桦木酸(2),羽扇豆醇(3),27-O-trans—caffeoylcylicodiscic acid(4),美洲茶酸(5),24-羟基美洲茶酸(6),二氢山萘酚(7),圣草素(8)。其中,化合物1是一个新的化合物,化合物3-4,7-8为首次从该种植物中分离得到。
In the present research, in order to study the chemical constituents ofPaliurus ramosissimus (Lour.) Poir., the isolation of its ingredients was performed by repeated chromatography on silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were elucidated on the basis of combination of mass spectrometry and 1D, 2D NMR spectroscopy. A total of 8 compounds were obtained, and their structures were identified as 313-hydroxy-27-(3,4-dihydroxybenzoyl)oxylup-20(29)-en- 28-oic acid (1), betulinic acid (2), lupeol (3), 27-O-trans-caffeoylcylicodiscic acid (4), ceanothic acid (5), 24-hydroxyceanothic acid (6), dihydrokaempferol (7), eriodictyol (8). Among them, compound 1 was a new compound. Compounds 3-4, 7-8 were isolated from Paliurus ramosissimus (Lour.) Poir. for the first time.
