摘　　要：目的:研究显齿蛇葡萄的化学成分。方法:用色谱法和光谱分析法分离和鉴定其化学成分。结果:分离并鉴定了7个化合物,分别为蛇葡萄素(Ⅰ),杨梅素(Ⅱ);杨梅甙(Ⅲ),没食子酸(Ⅳ),β-谷甾醇(Ⅴ),豆甾醇(Ⅵ),二氢槲皮素(Ⅶ)。结论:化合物Ⅳ、Ⅴ、Ⅵ、Ⅶ现为首次从该植物中得到,化合物Ⅶ为首次从蛇葡萄属植物中分得。Objective:To study the chemical constituents from Ampelopsis grossedentata (hand-Mazz) W.T.Wang.Methods: Chromatogra-phy and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant. Results: Seven compounds were isolated and elucidated as ampelopsin (Ⅰ) , myricetin (Ⅱ) , myricitrin (Ⅲ), gallic acid (Ⅳ), β-sitosterol (Ⅴ), stigmasterol (Ⅵ) and dihy-droquercetin (Ⅶ). Conclusion: Among these compounds, Ⅳ, Ⅴ , Ⅵ and Ⅶ were isolated from this plant for the first time, and compound Ⅶ was obtained from genus Ampelopsis for the first time.
