| 摘 要： | 为探讨中药提取物红外光谱用于中药药性识别的可行性,分别采用石油醚、乙酸乙酯、无水乙醇、水4种溶剂分部位提取桃仁等20种不同药性活血化瘀中药的化学成分,并用FTIR技术对各溶剂提取得到的成分进行分析测定,共采集得到240个傅里叶变换红外图谱。经对原始数据预处理后,应用主成分分析结合支持向量机方法对各样本的IR图谱进行分析。结果显示用乙酸乙酯提取物的红外光谱构建的模型对平性药识别正确率为80%,对非平性药的识别正确率为90%,平均识别正确率为85%。

| Abstract: | In order to study the feasibility of application of IR spectra to traditional Chinese medicine(TCM) property recognition,four different solvent sequences(petroleum ether,ethyl acetate,ethanol and water) were selected to extract the chemical components in 20 kinds of huoxuehuayu-TCM.After removing the solvents,the extracts of different solvent portion were determined by Fourier transform infrared(FTIR) spectrometry,and 240 IR spectra were obtained.Subsequently,the raw data were preprocessed,and the relations... |
