Objective: To study flavonoids of Zanthoxyli Pericarpium(ZP) correlated with appearance color and provide a reference for its quality evaluation. Method: Introducing chroma space system CIE L*
a*
b* to quantify of ZP's powder color objectively. Studying its correlation with color values by the indexes of total flavonoids
rutin
hyperoside
quercetin
and hesperidin. Result: Zanthoxylum bungeanum's content of total flavonoids
rutin and quercetin are positive correlated with L* and a* significantly (P<0.05). There is no significant correlation between total flavonoids
lutin and b*. The content of hyperoside and quercetin are positive correlated with b* significantly (P<0.05). Z. schinifolium's content of hesperidin is negative correlated with L*
a* and b* significantly (P<0.05). Conclusion: There is a certain degree of correlation between ZP's total flavonoids
