目的：甘草是我国常用大宗药材，研究甘草颜色与高效液相色谱（HPLC）指纹图谱的相关性对推动传统学科发展创新具有重要意义。方法：运用颜色数字化方法对甘草断面颜色进行定量分析，利用HPLC开展甘草指纹图谱分析，并对二者进行典型相关分析。结果：甘草断面颜色与HPLC指纹图谱信息之间有显著相关性。结论：颜色数字化指标值在一定程度内可以反映指纹图谱的分析结果。

Glycyrrhizae Radix et Rhizoma is one of the traditional herbal medicine used in China, study on the correlation between the cross- section color and HPLC fingerprints of them have important significance for promoting the development of traditional disciplines. Quantitative analysis of the color of sample cross section was carried out by color digital method, fingerprint analysis was carried out by HPLC, and the canonical correlation analysis was carried out between them. The results showed that there was a significant correlation between the color of Glycyrrhizae Radix et Rhizoma cross section and the information of HPLC fingerprinting. Results indicated that, The digitized indexes of color of cross section could reflect the result of fingerprint analysis to some extent.
