摘　　要：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-galactopy...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1Hand13C NMR数据。
