摘要:
目的: 研究青钱柳的水溶性成分。 方法: 利用反相色谱的方法分离纯化,根据化合物的化学性质与光谱数据鉴定结构。 结果: 青钱柳的70%乙醇提取物中分得7个化合物,确定其结构分别为山奈酚-3-O-β-D-吡喃葡萄糖醛酸钠盐(kaempferol-3-O-β-D-glucuronate sodium,Ⅰ)、槲皮素-3-O-β-D-葡萄糖醛酸钠盐(quer-eetin-3-O-β-D-glucuronate sodium,Ⅱ)、杨梅素-3-Oβ-D-葡萄糖醛酸钠盐(myricetin-3-O-β-D-glucuronate sodi-um,Ⅲ)、2,6-二甲氧基-4-羟基苯酚-1-O-β-D-吡喃葡萄糖苷(2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-gluco-pyranoside,Ⅳ)、色氨酸(tryptophan,Ⅴ)、没食子酸(gallic acid,Ⅵ),苯甲酸(benzoic acid,Ⅶ)。 结论: 化合物Ⅰ～Ⅵ为首次从该属中分得。
Abstract:
Objective: To study the water-soluble constituents from Cyclocarya paliurus(Batal)Ijinskaja Methods: The constitu-ents were isolated by reverse-phased materials,and their structures were characterized by chemical property and spectral analysis. Results: Seven compounds were isolated from the 70% ethanol extract of the leaves of Cyclocarya paliurus.Their structures were elucida-ted as kaempferol-3-O-β-D-glucuronate sodium(Ⅰ),quercetin-3-O-β-D-glucuronate sodium(Ⅱ),myricetin-3-O-β-D-glucuronate so-dium (Ⅲ),2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside(Ⅳ),tryptophan(Ⅴ),gallic acid(Ⅵ)and benzoic acid (Ⅶ)respectively. Conclusion: CompoundsⅠ～Ⅵare isolated from this genus for the first time.
