摘要

目的:探讨牡丹皮L*、a*、b*颜色与贮藏期的关系。方法:采用光密度计，采用CIE 1976 L~*， A ~*，b~*颜色体系，对筛选后的粉末和切片样品进行反射光测量。采用高效液相色谱法测定丹皮酚的含量。分析了牡丹皮贮藏期、丹皮酚含量与颜色指标的相关性。结果:测得的颜色与贮藏期呈显著相关。随着贮藏时间的延长，牡丹皮的颜色逐渐向红色偏移。贮藏期与丹皮酚含量呈正相关。测得的颜色与丹皮酚含量呈均匀相关。结论:本研究发现牡丹皮颜色与贮藏期存在相关性。测定牡丹皮的颜色可用于评价牡丹皮的贮藏期和质量。

[Study on Appraising Storage Periods of Moutan Cortex and Its Quality by Means of Colorimeter].

Objective: To examine the correlation between storage periods and L*, a* and b* color of Moutan Cortex.

Methods: A optical density meter was used for the measurement of reflected light from sieved powder and section samples using the CIE 1976 L~*,a~*,b~* color system. The content of paeonol were determined by HPLC. The correlation between storage periods,paeonol content and color indices of Moutan Cortex was analyzed.

Results: The measured color was significantly correlated with storage periods. The color of Moutan Cortex shift toward the red with the increase of storage periods. The storage periods were correlated with paeonol content. The measured color was equably correlated with paeonol content.

Conclusion: The correlation between the color of Moutan Cortex and storage periods was found in this study. Measurment of the color of Moutan Cortex can be used to appraise its storage periods and quality.
