不同产地红曲的近红外漫反射光谱聚类分析鉴别

Identification of Red Kojic from Different Habitats with Oustering Analysis by Near-Infrared Diffuse Reflectance Spectrometry

目的:为红曲的生药鉴定提供一种新方法。方法:用土曲作对照,采用近红外漫反射光谱法结合聚类分析方法进行定性鉴别18个产地的用紫色红曲霉发酵制备而成的红曲药材。结果:可以有效地鉴别不同产地的红曲,结果与经典形态分类学的结果基本一致。结论:近红外漫反射光谱法是一种快速、简便、低耗的新型分析技术,可用于红曲等中药的质量控制。

Objective: To provide a new method for identifying Red kojic. Methods: Being controled with the Aspergillus terreus, near-in- lrared diffuse reflectance spectroscopy combining with clusering analysis was used in the identification of Red Kojic made by M. purpureus fer-mentation from 18 different habitats. Results: We can easily distinguish the Red Kojic from different habitats and the Aspergillus terreus. The results are consistent in some degree with that of morphologic study. Conclusion:This method is a new, rapid, simple and low cost assay tech-nique being able to be used in the quality control of Red Kojic.
