近红外光谱法对不同蒸制时间地黄的鉴别研究

Identification of Dihuang Steamed for Different Hours with Near-Infrared Spectrum

建立近红外光谱技术鉴别不同蒸制时间地黄的方法。以近红外光谱聚类分析法对不同蒸制时间的地黄样品进行了聚类鉴别,并与薄层色谱法进行了对比研究。结合TLC实验结果,近红外光谱聚类分析结果中不同炮制时间的地黄样品被准确、快速的区分开。用近红外漫反射光谱技术应用于地黄的鉴别分类是可行和有效的,具有独特的优点。

One new method for identification of Dihuang from different steamed hours with near-infrared spectrum was established.Clustering analysis was used to distinguish the difference among these Dihuang samplses steamed for different hours.And there was one comparison between NIRS and TLC.All these samples could be identified fast,well and ture.NIRS is a feasible and effective approach to identify Dihuang with unique virtue.
