三种蜡梅叶及其炒制品的FTIR指纹图谱-模式识别研究
FTIR Fingerprints-Chemical Pattern Recognition Research of Three Kinds of Chimonanthus and Fried Samples
摘要
Abstract
Objective: To classify the leaves of Chimonanthus nitens, Chimonanthus Salicifolius, Chimonanthus zhejiang and their fried samples, Discriminating equation was established to distinguish categories of raw materials. Methods: The spectra of three kinds of Chimonanthus and fried samples were determined by FTIR. Principal component analysis, clustering analysis and discriminative analysis were applied to classify three kinds of Chimonanthus leaves and fried samples from different areas according to the relative absorbance of common peaks between 400 to 4 000 cm- 1. Results: 26 samples were divided into four classes, the discriminating accuracy was 96%. Conclution :The method is rapid, simple and could be applied to evaluate the quality of Chimonanthus leaves without damaging to sample, and it is easy to identify the adulteration.关键词
