Objective Explored the correlation between color and several index components of Chuanminshen violaceum Sheh et Shan， aiming at providing a reference for rapid and efficient screening of high quality Chuanminshen violaceum.Method Spectrophotometer was used to determine the color value of Chuanminshen violaceum； hot leaching method， sulfuric acid-phenol method， ultra-high performance liquid chromatography method were used to determine water-soluble extract， alcohol-soluble extract， polysaccharide and imperatorin respectively. IBM SPSS Statistics 26.0 was used to analyze the correlation between color and index component.Result The value of L* had extremely significant negative-correlation with alcohol-soluble extract， water-soluble extract and imperatorin （P<0.01）， and significant negative-correlation with polysaccharide （P<0.05）. The value of ΔE^* had extremely significant negative correlation with water-soluble extract and imperatorin （P<0.01）， and significant negative correlation with alcohol-soluble extract and polysaccharide （P<0.05）. However， the values of a^* and b^* had extremely significant positive correlation with alcohol-soluble extract， water-soluble extract and imperatorin （P<0.01）， and significant positive correlation with polysaccharide （P<0.05）.Conclusion The color values can be used as the index for rapid identification of quality of Chuanminshen violaceum， which provided scientific basis for comprehensive assessment of the quality of Chuanminshen violaceum.
