灰毡毛忍冬与正品金银花的绿原酸含量比较

Comparative Study on Content of Chlorogenic Acid in Lonicera japonica and L. macranthoides

目的 :从有效化学成分绿原酸的含量评价灰毡毛忍冬的药用价值 ,以合理开发利用这一丰富的自然资源。方法 :采用高效液相色谱法比较湖南产灰毡毛忍冬与山东省和河南省产的正品金银花 (忍冬 )的绿原酸的含量。结果 :湖南省隆回县和新宁县产的灰毡毛忍冬中绿原酸含量分别为 4 0 0 %和 4 5 2 % ,山东省和河南省产的金银花中绿原酸的含量分别为 2 2 0 %和 2 4 6 %。结论 :灰毡毛忍冬中绿原酸的含量远远高于忍冬花。

Objective: To exploit and utilize reasonably the abundant natural resources by appraising the medicinal purposes of Lonicera macranthoides Hands Mazz through the content of the useful chemical constituents chlorogenic acid Method: The content of chlorogenic acid in the flowers of L macranthoides Hands Mazz in Hunan and L japonica Thunb in Henan and Shandong was compared by HPLC Result: The contents of chlorogenic acid were 4 00% and 4 52% in L macrathoides from Longhui and Xinning County of Hunan respectively The contents were 2 20% and 2 46% in L. japonica from Shangdong and Henan respectively. Conclusion: The content of chlorogenic acid in L macranthoides was higher than that in Lonicera japonica
