Nine compounds were isolated and purified by column chromatographic techniques including macroporous resin, silica gel, ODS, Sephadex LH-20, and preparative reversed-phase HPLC. Their structures were elucidated as taxifolin (1), naringenin (2), chalconaringenin (3), acacetin (4), quercetin 3-O-beta-D-galactopyranoside (5), 6-prenylnaringenin (6) xanthohumol (7), desmethylxanthohumol (8), xanthohumol B (9) on the basis of MS and NMR spectroscopic data analysis. Compounds 1-5 were isolated from Humulus lupulus for the first time.
通过大孔树脂、硅胶、ODS、葡聚糖凝胶LH - 20和制备型反相高效液相色谱等柱色谱技术分离并纯化出9种化合物。基于质谱和核磁共振光谱数据分析,确定它们的结构分别为紫杉叶素(1)、柚皮素(2)、查耳酮柚皮素(3)、刺槐素(4)、槲皮素3 - O - β - D - 吡喃半乳糖苷(5)、6 - 异戊烯基柚皮素(6)、黄腐酚(7)、去甲基黄腐酚(8)、黄腐酚B(9)。化合物1 - 5首次从啤酒花中分离得到。
