目的 研究显齿蛇葡萄的化学成分.方法 应用硅胶、聚酰胺、反相硅胶、Sephadex LH-20柱色谱和硅胶制备薄层色谱进行分离纯化, 根据理化常数和光谱分析鉴定结构.结果 从显齿蛇葡萄中分离并鉴定了4个黄酮类化合物: 二氢杨梅素(1), 杨梅素(2), 杨梅苷(3), 杨梅素-3-O-β-D-半乳糖苷 (4).结论 其中化合物4为首次从该属植物中分离得到,根据2D NMR正确归属了化合物1的1H and 13C NMR数据.
Chemical Constituents from Ampelopsis grossedentata
Aim To study chemical constituents from Ampelopsis grossedentata. Methods Separation and purification were performed by using silica gel, polyamide, reverse-phase silica gel, Sephadex LH-20 column chromatographic techniques and silica gel PTLC. Structures were determined by means of physicochemical properties and spectral analysis. Results Four flavonoids were separated and identified from Ampelopsis grossedentata including dihydromyricetin (1), myricetin (2), myricitrin (3), and myricetin-3-O-β-D-galactopyranoside (4). Conclusion Compound 4 was isolated from this genus for the first time, and 2D NMR techniques permitted the correct assignment of 1H and 13C NMR signals of 1.
