摘 要:目的:研究长梗秦艽(Gentiana waltoniiBurkill)的化学成分,为阐明其药效物质奠定基础。方法:通过大孔树脂、硅胶、sephadex LH-20、反相硅胶(Rp-18)柱层析及制备液相色谱(Prep LC)进行分离,根据化合物理化性质和光谱数据鉴定结构。结果:从该植物中分离鉴定了10个化合物,分别为:gentiolactone(1)、2-methoxy-anofinic acid(2)、4,6-二羟基-2-甲氧基苯乙酮(4,6-dihydroxy-2-methoxyacetophenone,3)、东莨菪素(scopoletin,4)、6′-(2,3-二羟基苯甲酰)当药苷酯(6′-(2,3-dihydroxybenzoyl)sweroside,5)、3′-乙酰基当药苷(3′-acetylsweroside,6)、4-O-2-羟基-6-甲氧基苯乙酮苷(4-O-glycosyloxy-2-hydroxy-6-methoxyacetophenone,7)、獐牙菜苦苷(swertiamarin,8)、当药苷(sweroside,9)和龙胆苦苷(gentiopicroside,10)。结论:化合物3、4和7为首次从龙胆属植物中分离得到,化合物1~10均为首次从该植物中分离得到。AIM: To evaluate the chemical constituents in Gentiana waltonii Burkill. METHODS: Isolation and purification of the compounds were carried out by column chromatography with maernporous resin, silica gel, Sephadex LH-20, Rp-18 silica gel and preparative HPLC. Struetural identification of eompotunds was based on spectral data analysis. RESULTS: Ten compounds were obtained from Gentiana waltonii and identified as gentiolactone (1), 2-methoxyannfinic acid (2), 4, 6-dihychroxy-2-methoxyacetophenone (3), scopoletin(4). 6′-(2, 3-dihydroxybenzoyl) sweroside (5), 3′-aeetylsweroside (6), 4-O-glycosyloxy-2-hydroxy-6-methoxyacetophenone (7), swertianmarin(8), sweroside (9) and gentiopicroside (10), CONCLUSION: Compounds 3, 4, and 7 were isolated from the genus Gentiana for the first lime. Compounds 1 ~ 10 were isolated from this planl for the first lime.
