摘    要:借助于黄芩的红外指纹图谱 ,采用主成分分析法对来自 15个产地的黄芩进行了聚类分析 ,将其分为 6个产区 ,这一分区与各产地的地理位置和气候条件有一定的相关性 ,同一产区内黄芩的化学组分相似 ,可作为中医界对黄芩药材质量评价的依据。用径向基函数人工神经网络法预测了 4 3个黄芩样本的产区 ,结果表明径向基函数人工神经网络法具有较强的预测能力 ,可区分和鉴别黄芩的产区。该法可用于药材产地的分类和鉴别 ,作为药材质量控制的手段之一。

关 键 词:红外光谱  黄芩产区  聚类分析  主成分分析  径向基函数网络

Abstract:Based on the infrared fingerprint spectra, scullcap samples from 15 geographical origins were clustered into 6 classes with principal component analysis. The classification was related to their geographical origins and weather. In the same class, chemical components of scullcaps are similar to each other, which can be considered as the criterion of evaluating the quality of scullcaps. 43 geographical origins were predicted with radial basis function, which was demonstrated to be a powerful ANN method in discrimination. The classes of scullcaps can be distinguished by the method. The method can be used to class and identify geographical origins of scullcaps. It is one of the methods in the quality control of traditional Chinese medicines.
Keywords:FTIR spectroscopy  Geographical origin of scullcaps  Clustering analysis  Principal component analysis  Radial basis function networks
