摘要
目的:测定重庆主产地不同年龄灰毡毛忍冬枝叶中总黄酮的含量.方法:采用紫外分光光度计测定法.结果:灰毡毛忍冬叶片和枝条都含有较多的黄酮类物质,其中含量变化为叶片大于枝条,嫩叶大于老叶.不同年龄灰毡毛忍冬叶片之间和枝条之间存在着显著性差异.而不同个体之间的总黄酮含量也有一定的差异.结论:灰毡毛忍冬叶片和枝条都有很好的开发利用价值.
Objective： To determine the contents of total flavones in the leaves and branches of Lonicera nuwranthoides of different ages in Chongqing. Methods： UV spectrophotometry. Results. Abundant flavone substances were found to exist in the leaves and branches of L. nuwranthoides. The leaves contained more flavones than the branches, and the young leaves contained more flavones than the older leaves. Significant differences were observed between the leaves of different ages and branches of different ages in their fla- vone contents. The content of total flavones was also significantly different between different plants. Conclusion; The leaves and branches of L. nuwranthoides have great value for development and exploitation.
