摘要: 为了进一步研究多叶棘豆的化学成分,本文采用正相硅胶柱、Sephadex LH-20柱色谱法及制备高效液相色谱法,从蒙药多叶棘豆中分离纯化10个黄酮类化合物。经各种波谱分析法鉴定其结构分别为:4,4′-二甲氧基-2′-羟基查尔酮(1)、2′,4′-二羟基-4-甲氧基查尔酮(2)、7,8-二羟基二氢黄酮(3)、4,2′,4′-三羟基查尔酮(4)、2′,4′-二羟基二氢查尔酮(5)、4′-羟基二氢黄酮-7-O-β-D-葡萄糖苷(6)、2′,4′-二羟基查尔酮(7)、芹菜素(8)、芹菜素-7-O-β-D-葡萄糖醛酸苷(9)和 3′,7-二羟基-2′,4′-二甲氧基异黄烷(10)。其中,化合物1~9均为首次从该植物中分离。

Abstract: Ten flavonoids were separated and purified from Oxytropis myriophylla (Pall.) DC.by silica gel column chromatography,Sephadex LH-20 and preparation HPLC,etc. Based on the spectral analysis,their structures were elucidated as 4,4′-dimethoxy-2′-hydroxychalcone (1),2′,4′-dihydroxy-4-methoxychalcone (2), 7,8-dihydroxyflavonone (3), 4,2′,4′-trihydroxychalcone (4),2′,4′-ihydroxydihydrochalcone (5),4′-hydroxy flavonone-7-O-β-D-glucoside (6),2′,4′-dihydroxychalcone (7), apigenin (8), apigenin-7-O-β-D-glucuronide (9) and 3′,7-dihydroxy-2′,4′-dimethoxyisoflavan (10).Compounds 1-9 were isolated from this plant for the first time.

Key words: Oxytropis myriophylla (Pall.) DC., flavonoid component, structural identification
