青钱柳水溶性成分的研究

Studies on water-soluble constituents in the leaves of Cyclocarya paliurus

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。

Objective： To study the water-soluble constituents from Cyclocarya paliurus （Batal） Ijinskaja Methods： The constituents 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 elucidated as kaempferol-3-O-β-D-glucuronate sodium （Ⅰ）, quercetin-3-O-β-D-glucuronate sodium （Ⅱ）, myricetin-3-O-β-D-glucuronate sodium （Ⅲ）, 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside （IV）, tryptophan （Ⅴ）, gallic acid （Ⅵ） and benzoic acid （Ⅶ） respectively. Condusion： Compounds Ⅰ -Ⅵ are isolated from this genus for the first time.
