摘　　要：目的:探讨姜黄提取物的红外光谱学特性。方法:采用红外光谱法对11批不同产地的姜黄浸出物样品进行检测,采用红外光谱软件Omnic 8.0求出平均图谱,并检测各样品间的相似度。结果:获得各样品的红外光谱图及特征吸收峰;姜黄药材各样品浸出物的IR相似度在0.999 2~0.921 1范围内,因此拟定姜黄药材浸出物的IR相似度阈值为0.90。结论:采用红外光谱法鉴定姜黄具有专属性强、灵敏度高、取样量小、简便迅速等特点,可作为姜黄的质量控制方法。Objective：To explore the characteristics of infrared spectra ofCurcuma longaL.. Methods： Curcuma longa L. extracts samples from 11 different producing areas were studied with infrared spectrometry, and used infrared spectroscopy software Omnic 8. 0 to calculated the average map and their similarity. Results： The infrared spectra of Curcuma longaL, extracts samples were obtained,the similarity of all the samples varied between 0. 921 1-0. 999 2 （the threshold value being 0. 90）. Conclusion： These methods are specificity, sensitive, simple,rapid and the sampling volume is small and can be used as the authenticity of identification method for Curcuma longa L. extracts samples.
