目的:对宽叶大戟全草的化学成分作进一步的分离和鉴定。方法:采用色谱分离技术进行分离纯化,通过波谱分析鉴定化合物结构。结果:从宽叶大戟全草中分离得到10个化合物,分别为:没食子酸(Ⅰ)、苯甲酸(Ⅱ)、丁香苷(Ⅲ)、正丁基-β-吡喃果糖苷(Ⅳ)、乙基-β-D-吡喃果糖苷(Ⅴ)、(6S,9R)-6-羟基-3-酮-α-紫罗兰醇-9-O-β-D-葡萄糖苷(Ⅵ)、尿嘧啶(Ⅶ)、腺嘌呤(Ⅷ)、棕榈酸单甘油酸(Ⅸ)、棕榈酸(Ⅹ)。结论:化合物Ⅰ~Ⅹ均为首次从宽叶大戟全草中分离得到。 OBJECTIVE: To further isolate and identify the chemical constituents of wholegrass. Methods: The chromatographic separation technique was used for separation and purification. The structure of the compounds was identified by spectral analysis. RESULTS: Ten compounds were isolated from the whole plant of B. grandis: gallic acid (I), benzoic acid (II), syringin (III), n-butyl-β-fructopyranoside (IV) , Ethyl-β-D-fructopyranoside (V), (6S,9R)-6-Hydroxy-3-one-α-ionol-9-O-β-D-glucoside (VI), urine Pyrimidine (VII), adenine (VIII), palmitic monoglyceride (IX), and palmitic acid (X). Conclusion: Compounds I~X were isolated from the whole plant of B. grandis for the first time.
