摘要
本文以中药材黄芩为研究对象,对5种黄芩共10个样品进行了紫外光谱分析,所得数量化特征用主成分分析的数学方法进行压缩,概括出不同样品化学成分的异同,实现了对黄芩质量的综合评价。
10 samples from five species of the traditional Chinese drug Huangqin(Radix Scutellariae)have been examined by means of ultraviolet spectrometry. All of the obtained characteristicfeatures of quantization were treated with mathematic method of principal component analysis.The differences of chemical components of samples were summarized and the synthetical qualityevaluation of the traditional Chinese drug Huangqin was realized.
