)hmx 263, 315 rim. The UV spectrum was characteristic for isoflavone derivatives. The PMR spectrum showed signals of the protons H-5 (8.18 ppm, d, 8.0 Hz), H-2 (7.93 ppm, s), H-6 (7.18 ppm, dd, 8.0 and 2.0 Hz), and H-8 (7.04 ppm, d, 2.0 Hz), of an anomeric proton (5.63 ppm, d, 6.5 Hz), and of the other protons of the carbohydrate moiety (3.90-4.55 ppm). The acid hydrolysis of substance (1) gave daidzein
补骨脂属植物(faro. Fabaceae)富含呋喃香豆素,其中一些具有抗哮喘、抗歇斯底里和抗癫痫作用。药物补骨脂素和psoberan在药用药物中用作治疗白斑和斑秃的光敏剂[1]。先前已在补骨脂科 Bunge(核果皮豌豆)的根中检测到呋喃香豆素补骨脂素和当归素 [2, 3]。1989 年 9 月在哈萨克斯坦共和国阿利姆套附近收集的植物粉碎的风干根(400 克)用乙醇彻底提取。真空浓缩醇提物,用水稀释,依次用氯仿和乙酸乙酯萃取。在己烷-氯仿 (9: 1)系统导致补骨脂素和当归素的分离。在氯仿-甲醇 (9:1) 系统中对硅胶上的乙酸乙酯级分进行色谱分离,分离出类黄酮 (1)。Daidzin (1) (daidzein 7-O-fl-D-glucopyranoside) -C2tH2009, mp 235-236"C, )hmx 263, 315 rim。紫外光谱是异黄酮衍生物的特征。PMR光谱显示质子信号H-5
