【摘要】 研究桑科葎草（Humulus scandens）茎叶石油醚部位化学成分。采用硅胶、Sephadex LH-20、ODS、制备型高效液相等色谱方法进行分离纯化，从桑科中药葎草（Humulus scandens）茎叶中分离得到15个化合物，应用理化数据和波谱学方法分别鉴定为杨芽黄素（1）、白杨素（2）、5-羟基-3,4’,6,7-四甲氧基黄酮（3）、（2S）-5-羟基-7,8-二甲氧基二氢黄酮（4）、欧前胡素（5）、珊瑚菜内酯（6）、4-羟基-3-(3’-甲基-2’-丁烯基)苯甲酸乙酯（7）、对羟基苯丙酸（8）、反式对羟基肉桂酸乙酯（9）、对羟基苯甲醛（10）、anofinic acid(11)、5,6-去氢卡文内酯（12）、大黄素甲醚（13）、齐墩果-12-烯-3,11-二酮（14）、ergosta-4,6,8(14),22-tetraen-3-one(15)，以上化合物均为首次从该植物中分离得到。更多还原

【Abstract】 To study the chemical constituents of petroleum ether extract from the stems and leaves of Humulus scandens (family of Moraceae),fifteen compounds were isolated from the stems and leaves of H.scandens by silica gel,Sephadex LH-20,ODS,and preparative HPLC chromatography.The structures were identified by physicochemical data and spectroscopic method as tectochrysin (1),chrysin (2),5-hydroxy-3,4’,6,7-tetramethoxyflavone (3),(2S)-5-hydroxy-7,8-dimethoxyflavanone (4),imperatorin (5),phellopterin (6),ethyl 4-hydroxy-3-(3’-methyl-2’-butenyl)benzoate (7),p-hydroxy-phenylpropionic acid (8),ethyl p-hydroxycinnamate (9),p-hydroxybenzaldehyde (10),anofinic acid (11),5,6-dehydrokavain (12),physcion (13),olean-12-ene-3,11-dione (14) and ergosta-4,6,8 (14),22-tetraen-3-one (15),respectively.All compounds were isolated from this plant for the first time.更多还原
