Abstract

Objective: To study the relationship between the component content of curcuminoids in Curcumae Longae Rhizoma and powder color indeces L*, a* and b* those were measured by chromaticity instrument, in order to provide scientific basis for quality assessment of Curcuma longa medicinal materials.

Methods: Detect the content of curcumin,demethoxycurcumin,bisdemethoxycurcumin,then detect the content of curcuminoids by the Chinese Pharmacopoeia method. Measure the color indeces L*, a* and b* of Curcumae Longae Rhizoma powder by colorimeter. Finally, the relationship between the content and the color was analyzed by using the Grey Relational Analysis, Pearson correlation coefficient and regression analysis.

Results: There was positive correlation between the content of curcuminoids and a*. But there was no definitely relation between the content of curcuminoids and b* or L*.

Conclusion: The content of curcuminoids is closely related with the degree of the color red, the higher the content, the red is deeper. a* could be recognized as an important basis of Curcumae Longae Rhizoma medicinal materials quality.

[姜黄根粉中姜黄素与颜色指数L*、a*、b*的相关性分析]。

目的:研究姜黄中姜黄素成分含量与色度仪测定的粉末颜色指数L*、a*、b*之间的关系，为姜黄药材质量评价提供科学依据。方法:测定姜黄素、去甲氧基姜黄素、双去甲氧基姜黄素的含量，再按《中国药典》方法测定姜黄素的含量。用比色仪测定莪术粉末的颜色指数L*、a*、b*。最后，运用灰色关联分析法、Pearson相关系数分析法和回归分析法对内容与颜色之间的关系进行分析。结果:姜黄素含量与a*呈正相关。但姜黄素的含量与b*或L*之间没有明确的关系。结论:姜黄素含量与颜色呈红色的程度密切相关，含量越高，红色越深。a*可作为姜黄药材质量的重要依据。
