摘要
综合利用各种色谱方法对黄药子的乙醇提取物进行分离,从中共得到23个化合物。通过波谱分析结合文献数据比对,将它们的结构分别鉴定为:2,7-二羟基-3,4-二甲氧基菲(1)、7-羟基-2,3,4-三甲氧基菲(2)、3,7-二羟基-2,4-二甲氧基-9,10-二氢菲(3)、3-羟基-2,4,7-三甲氧基-9,10-二氢菲(4)、2-羟基-3,4,7-三甲氧基-9,10-二氢菲(5)、7-羟基-2,3,4-三甲氧基-9,10-二氢菲(6)、7-羟基-2,4-二甲氧基-9,10-二氢菲(7)、2-羟基-4,7-二甲氧基-9,10-二氢菲(8)、2,7-二羟基-3,4-二甲氧基-9,10-二氢菲(9)、2'-羟基-3,4,5-三甲氧基联苄(10)、2',3-二羟基-4,5-二甲氧基联苄(11)、3-羟基-4,5-二甲氧基联苄(12)、3,5-二羟基-4-甲氧基联苄(13)、pteryxin(14)、praeruptorin A(15)、山柰酚(16)、7,3',4'-三羟基-3,5-二甲氧基黄酮(17)、黄独乙素(18)、diosbulbin G(19)、3-羟基-β-突厥酮(20)、(6S,9S)-吐叶醇(21)、(6S,9R)-吐叶醇(22)和blumenol B(23)。其中,化合物4~8、10、12~15、20~23共14个化合物均为首次从该植物中分离得到。
Twenty-three compounds were isolated from the ethanol extracts of rhizomes of Dio sco rea b u lb i fe ra by applica-tion of various chromatographic methods. Based on spectrum analyses in combination with literature data comparison, their structures were identified as 2,7-dihydroxy-3 ,4-dimethoxyphenanthrene (1) ,7-hydroxy-2,3,4-trimethoxyphenan- threne (2) ,3,7-dihydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene ( 3 ) ,3-hydroxy-2,4,7-trimethoxy-9,10-dihydro- phenanthrene (4) ,2-hydroxy-3,4,7-trimethoxy-9,10-dihydrophenanthrene ( 5 ) ,7-hydroxy-2,3,4-trimethoxy-9,10-di- hydrophenanthrene (6) , 7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene ( 7 ) , 2-hydroxyl, 7-dimethoxy-9,10-di-hydrophenanthrene (8) , 2,7-dihydroxy-3,4-dimethoxy-9,10-dihydrophenanthrene ( 9 ) , 2 ' -hydroxy-3, 4 , 5 -trimethoxy- bibenzyl (10) ,2?,3-dihydroxy5-dimethoxybibenzyl (11 ) ,3-hydroxyl,5-dimethoxybibenzyl (1 2 ) , 3 ,5-dihydroxy methoxybibenzyl (13) ,pteryxin (14 ) ,praeruptorin A (1 5 ) ,kaempferol (1 6 ) , 7 , 3' ,4'trihydroxy-S ,5-methoxyflavone (17) ,diosbulbin B (18) ,diosbulbin G (19) ,3-hydroxy-/3-damascone (20 ) , ( 6 5 , 9 5 ) -vomifoliol (21 ) , (65,9%)-vom- ifoliol (22) ,blumenol B (23) Respectively. Among t h e m ,fourteen compounds including 4-8,10,12-15,20-23 were i-dentified from D. b ulbi fe ra for the first time.
