OBJECTIVE
To study the chemical constituents of flavonoids from Apocynum venetum L.
METHODS
The compounds from water extracts were isolated by HPD-100 MCI-gel, polyamide, silica and Sephadex LH-20. Their structrues were characterized by chemical methods and spectroscopic methods.
RESULTS
The five compounds were identified to be trifolin (I), hyperroside (III), hyperin (V), isoquercetin-6'-o-acetate (VII) and isoquercetin (VIII).
CONCLUSION
Compound I and compound VII are isolated from Apocynum venetum L. for the first time.
目的
研究罗布麻叶中黄酮类化学成分。
方法
采用HPD-100 MCI凝胶、聚酰胺、硅胶及葡聚糖凝胶LH-20柱色谱从罗布麻叶水提取物中分离化合物，并通过化学方法和波谱方法鉴定其结构。
结果
鉴定出5个化合物，分别为三叶豆苷（I）、金丝桃苷（III）、槲皮素（V）、异槲皮素-6'-O-乙酸酯（VII）和异槲皮素（VIII）。
结论
化合物I和化合物VII为首次从罗布麻叶中分离得到。
