目的:研究白梅花的化学成分。方法:采用硅胶柱色谱分离,通过理化常数和波谱分析鉴定化合物的结构。结果:从白梅花中分离并鉴定了8个化合物,分别为:苯甲酸(Ⅰ)、异鼠李素(Ⅱ)、槲皮素(Ⅲ)、山奈酚3-O-β-D-吡喃半乳糖苷(Ⅳ)、异鼠李素-3-O-β-D-吡喃葡萄糖苷(Ⅴ)、异槲皮苷(Ⅵ)、金丝桃苷(Ⅶ)、芦丁(Ⅷ)。结论:其中化合物Ⅱ~Ⅶ均为首次从该植物中分离得到。
Objective: To study the chemical composition of white plum blossoms. METHODS: Silica gel column chromatography was used to determine the structure of the compounds by physicochemical constants and spectral analysis. Results: Eight compounds were isolated and identified from white plum blossoms: benzoic acid (I), isorhamnetin (II), quercetin (III), kaempferol 3-O-β-D-pyran Galactoside (IV), isorhamnetin-3-O-β-D-glucopyranoside (V), isoquercitrin (VI), hyperoside (VII), rutin (VIII). Conclusion: Compounds II~VII were isolated from this plant for the first time.
