Abstract:
To explore the correlation between color of Glycyrrhiza uralensis and its quality evaluation,the colors of root bark and transverse section were determined by Precision Color Reader and Visual Analyzer,and the contents of six flavonoids and two saponins in G.uralensis were determined by high performance liquid chromatography（HPLC）.The partial least squares regression（PLSR）method was employed to correlate the colors with component contents in G.uralensis. The results showed that there were no significant differences in the colors of root bark but significant or very significant differences（P<0.05,P<0.01）in the colors of transverse section between the wild and cultivated G. uralensis. Compared with those in the cultivated G. uralensis, the contents of liquiritin, isoliquiritin isoliquiritigenin and the contents of ammonium glycyrrhizinate, glycyrrhetinic acid were obviously significant or remarkably significant in the wild G. uralensis.The correlation results showed that there was a significant or very significant correlation between the colors and the effective component contents. This study provides a scientific basis to evaluate the quality of G.uralensis by color and a new reference for the traditional evaluation methods for Chinese drugs.
