摘　　要：目的探讨罗布麻叶中黄酮类成分的分布特点与动态积累规律。方法采用高效液相色谱法(HPLC)同时测定不同生长部位和生长期罗布麻叶中5种黄酮类成分。结果紫云英苷含量呈现出上部叶>中部叶>下部叶的规律;金丝桃苷、异槲皮苷的含量以6、7月份较高。结论为罗布麻叶的生态分析、合理采收以及资源开发利用提供有价值的资料。OBJECTIVE To investigate distribution and accumulation of flavonoids in the Folium Apocyni Veneti.METHODS HPLC was established to determine the contents of the five flavonoids in the leaves from different growing periods and regions.RESULTS The content of astragalin in Folium Apocyni Veneti from different regions showed a decreasing trend,while hyperin and isoquercitrin were higher on June and July.CONCLUSION This study provides a reliable scientific material about the ecological analysis,the reasonable harvest and the exploitation of Folium Apocyni Veneti.
