摘　　要：目的:探讨重叠率在植物以及植物提取物指纹谱研究中的地位和应用。方法:以绿茶和茶多酚的HPLC指纹谱为例来进行说明。结果:重叠率可为绿茶和茶多酚的特征指纹谱选择有代表性的样品,并可依之推断茶多酚样品的提取原料、工艺以及生产厂家等。结论:重叠率可作为建立特征指纹谱样品筛选的有力依据,并可为产品与原料、工艺间相互关系的探究提供参考。AIM： To discuss the application of overlapping ratio to the fingerprints of plant and plant extract. METHODS ： We took the HPLC fingerprints of green tea and tea polyphenols for decision procedure. RESULTS ： Overlapping ratio could be applied to selecting representative samples for characteristic fingerprints of green tea and tea polyphenols, and could be used to deduce the raw material, process and producer of tea polyphenols. CONCLUSION： Overlapping ratio can be used to choose the suitable samples for establishing the characteristic fingerprint spectrum, and can supply references to relationship investigation among products, raw material and process.
