目的:研究白木香叶的化学成分。方法:应用溶剂法和色谱法分离纯化化合物,利用谱学技术鉴定化合物结构。结果:分离得到33个化合物,本文鉴定12个化合物的结构,分别为5-羟基-7,4’-二甲氧基黄酮(1)、金合欢素(2)、木犀草素(3)、芫花素(4)、芫花苷(5)、腺苷(6)、芫花素-5-O-β-D-吡喃葡萄糖苷(7)、高次衣草素-7-O-β-D-吡喃葡萄糖苷(8)、次黄嘌呤(9)、尿嘧啶(10)、8-C-β-D-半乳糖基异牡荆素(11)、4-(1,2,3-三羟基丙基)-2,6-二甲氧基苯-1-O-β-D-葡萄糖苷(12)。结论:除化合物1,3,4外,化合物2,5～12均为首次从白木香叶中分离得到。 Objective: To study the chemical constituents of white wood. Methods: The compounds were isolated and purified by solvent method and chromatography. The structures of the compounds were identified by spectroscopic methods. Results: A total of 33 compounds were isolated. The structures of 12 compounds were identified as 5-hydroxy-7,4’-dimethoxyflavone (1), acacetin (2), luteolin (4), Daphne (5), Adenosine (6), Daphnetin-5-O-β-D-glucopyranoside (7) β-D-glucopyranoside (8), hypoxanthine (9), uracil (10), 8- , 3-trihydroxypropyl) -2,6-dimethoxybenzene-1-O-β-D-glucoside (12). Conclusion: Compounds 1, 2, 3 and 5 are the first isolated from the white leaf of Perilla frutescens.
