目的：基于色度学理论，引入分光测色计，建立甘草断面及表皮颜色指标数字化的方法。为传统中药性状鉴别中感官颜色的客观化、数字化提供新方法、新思路。方法：基于CIE1976L*a*b*均匀色空间系统，以甘草为研究对象，针对样品断面及表皮的具体情况，选用2种分光测色计分别制订了甘草断面和表皮颜色的测量方法。结果：确定了去皮打粉的断面颜色量化方法和以直接测量为主、湿法施压剥皮测量为辅的表皮颜色量化方法，摸索并确定了RSD和dE*ab双指标评价方法。结果表明此方法有效、可行。结论：本颜色测量方法简便、可靠，测量结果可以如实的反映药材颜色情况，并将主观的颜色描述用客观的数据表示，为揭示中药传统性状鉴别深层内涵提供了实验依据。

This study was aimed to establish a method for sensorial color digitalization of Chinese herbal medicines (CHMs) with the application of spectrocolorimeter. The discussion was focused on difficulties of distinguishing surface and section color of CHMs. Based on uniform color space system of CIE1976L*a*b*, two methods for determination of section and surface color were constructed with two different kinds of spectrocolorimeters taking Glycyrrhizae Radix et Rhizoma as the experimental objective. In this paper, different kinds of sample preparation methods were used. Based on results, the method of scraping and grinding was proposed to prepare samples for section color determination. The method of wet pressing and peeling was proposed to prepare samples for surface color determination. Besides, RSD and dE*ab were served as evaluation indexes. This paper provided a simple, rapid and reliable analysis method for the color determination of CHMs. It also gave insight to future research on digitalization and modernization of CHMs' organoleptic characteristics based on traditional macroscopic identification.
