摘 要:为综合利用白木香叶的丰富资源,阐明其物质基础,课题组再次对其化学成分进行了研究,采用多种色谱技术对其化学成分进行分离纯化,从白木香叶95%,70%乙醇提取物的氯仿和正丁醇萃取部位共分离得到12个化合物。经多种波谱方法鉴定其结构,分别为鸢尾酚酮2-(0-α-L)-吡喃鼠李糖苷(1),4’-羟基-5-甲氧基黄酮-7-0-葡萄糖(6-1)木糖苷(2),7,3’,5’.三甲氧基黄酮苷(3),5-甲氧基芹菜素7-(D-β-D)-葡萄糖苷(4),2-苯乙基1-O-β-D-吡喃葡萄糖苷(5),红景天苷(6),苯甲醇1-O-β--D.吡喃葡萄糖苷(7),2,6-二甲氧基4一羟基苯酚-1-β-D-吡喃葡萄糖苷(8),vanilloloside(9),(+)-丁香脂素(10),β-维生素E(11),豆甾-5-烯-3β,7α-二醇(12),化合物2,3,5—9,11和12为首次从该属植物中分离得到。另外,对氯仿萃取部位的9个流分进行了4种人体肿瘤细胞毒活性筛选,均未显示明显活性。To comprehensively utilize the rich resource of Aquilaria sinensis, the ethanol extract of the leaves of A. sinensis was further chemically investigated, which led to the isolation of 12 compounds. By means of 1H- , 13 C-NMR, and ESI-MS data, and through comparison with those reported in literatures, their structures were identified as iriflophenone 2-(O-a-L)-rhamnoside (1) ,4'-hydroxy-5 methoxyflavone-7-O-glucoxyloside(2) ,7,3' ,5'-tri-O-methyhricetin(3) ,7-O-β--D-glucopyranoside of 5-O-methylapigenin(4) ,2-phenyl- ethyl-D-glucopyranoside ( 5 ), salidroside, ( 6 ), benzyl alcohol O-β-D-glueopyranoside ( 7 ), 2,6-dimethoxy-4-hydroxyphenol-1 -O-β-D- glucopyranoside (8), vanilloloside ( 9 ), ( + ) -syringaresinol( 10 ) β-tocopherol ( 11 ) and stigmast-5-ene-3/3,7a-diol ( 12 ). Among them, compounds 2,3,5-9,11 and 12 were isolated from this genus for the first time. This research hopefully provides valuable data for the further utilization and development of the leaves of A. sinensis.
