摘要

目的：引入分光测色计，将中药材性状品质这一经验指标数据化，依据获取的中药材颜色信息实现对中药材品种的鉴别，为研究中药鉴定共性技术问题提供一种新的方法及思路。方法：以陈皮为研究对象，在全国范围内收集陈皮药材，采用色度学分析方法获取陈皮颜色特征参数，通过统计分析，建立陈皮品种鉴别的数学预测模型和90%参考值范围。结果：建立了基于L*a*b*色度空间的陈皮药材品种鉴别的数学判别模型，其判别符合率为100%，双侧90%参考值范围分别为陈皮：L*（66.621 5～73.916 5），b*（29.329 5～52.211 0）；广陈皮：L*（53.950 0～63.260 0），b*（24.610 0～30.770 0）。结论：实验证明分光测色计获取的颜色信息可实现陈皮药材品种的鉴别，采用色度学分析方法对中药品种鉴别具有一定的可行性。

Abstract

Objective: To datalize the property and quality of Chinese medicine

identify the different species of Citri Reticulatae Pericarpium by its color information after using spectrocolorimeter

and provide a new method and idea for the study of common technical problems of traditional Chinese medicine. Method: Citri Reticulatae Pericarpium herbs were collected nationwide

and its color information was obtained by using spectrocolorimeter. According to the statistical analysis

a mathematical model for the identification of Citri Reticulatae Pericarpium species and 90%reference value scale were established. Result: A mathematical model for the identification of Citri Reticulatae Pericarpium species based on L*a*b* chromaticity space was established

with a coincidence rate of 100%; bilateral 90% reference range was as follows Citri Reticulatae Pericarpium: L*(66.621 5-73.916 5)

b*(29.329 5-52.211 0); Citri Reticulatae Chachiensis Pericarpium: L*(53.950 0-63.260 0)

b*(24.610 0-30.770 0). Conclusion: The color information from spectrocolorimeter can be used to accurately identify different species of Citri Reticulatae Pericarpium.
