摘　　要：目的:研究金银花有效成分含量与颜色值之间的相关性。方法:尝试从传统中医药传统经验角度出发,引入色度计对金银花粉末颜色进行测量,同时结合药材内部物质成分含量测定结果,对二者间相关性进行研究分析。结果:绿原酸含量与明度值L*的相关系数为-0.564,P=0.015;木犀草苷与明度值L*的相关系数为0.396,P=0.103;总黄酮与明度值L*的相关系数为-0.616,P=0.006。结论:金银花中绿原酸和总黄酮含量与L*值存在显著的负相关关系,木犀草苷含量与L*值不显著相关,金银花的颜色值主要与金银花中所含有的总黄酮含量有关。Objective：To study the correlation between the content of active ingredients and color values of Lonicera japonica.Methods：From the view of traditional Chinese medicine experience,colorimeter was used to measure the color of Lonicera japonica powder.Meanwhile,with the methods of HPLC and UV the amount of effective constituents of Lonicera japonica was determined,the correlation had been analyzed.Result：There was significant correlation between L^＊ and chlorogenic acid,total flavonoids（probability value P=0.015 and P=0.006）,but not much more correlation with galuteolin.The color index L^＊ was influenced by those three effective constituents to the extent of 43.1%.And with value of L^＊,a^＊,b^＊,the amount of total flavonoids could be speculated to the extent of 46.7%.Conclusion：It could be feasible to evaluate the quality of Chinese Materia Medica with the application of colorimeter.
