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。
Ten flavonoids were separated and purified from Oxytropis myriophylla ( Pall. ) DC. by silica gel column chro- matography, 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'-dihydroxydihydrochalcone (5), 4'-hydroxy flavanone-7 -O-β-D-glucoside ( 6 ), 2', 4'-dihydrexychalcone (7), apigenin (8), apigenin-7 -O-β-D-glucuronide (9) and 3',7-dihydrexy-2' ,4'-dimethoxyisofla- van (10). Compounds 1-9 were isolated from this plant for the first time.
