目的:研究紫藤瘤抗农作物病原性真菌活性部位化学成分。方法:利用硅胶、Sephadex LH-20等多种色谱法进行化合物分离纯化,根据波谱数据进行结构鉴定。结果:从活性部位中共分离鉴定了10个化合物,分别为:邻苯二甲酸二丁酯(1)、双丙酮醇(2)、松脂醇(3)、星鱼甾醇(4)、齐墩果酸(5)、12-齐墩果烯-3-酮-22,24-二醇(6)、白桦脂酸(7)、2’,4’,4-羟基-查尔酮(8)、扁蓄苷(9)、槲皮素-3-O-β-D-吡喃葡萄糖苷(10)。结论:所有化合物均为首次从该属植物中分离得到。
Objective: To study the chemical constituents of wisteria tumor against the active site of pathogenic fungi in crops. Methods: Compounds were isolated and purified by silica gel and Sephadex LH-20 chromatography. Their structures were elucidated on the basis of spectral data. Results: Ten active compounds were isolated and identified as dibutyl phthalate (1), diacetone alcohol (2), pinoresinol (3), star fish sterol (4), oleanolic acid (6), betulinic acid (7), 2 ’, 4’, 4-hydroxy-chalcone (8) Panax glycosides (9), quercetin -3-O-β-D-glucopyranoside (10). Conclusion: All the compounds were isolated from this genus for the first time.
