目的用电子舌技术对枳实(Aurantii Fructus Immaturus)药材产地来源进行鉴别。方法通过电子舌对不同产地样品的响应特点建立产地分类模型,用主成分分析(PCA)和判别因子分析(DFA)来判断测试枳实药材的产地归属,并用高效液相色谱法进行验证。结果市售的枳实药材主要分为江西类和四川类,电子舌对4种测试枳实药材的判断结果被高效液相色谱法所验证。结论电子舌能够有效鉴别未知产地来源的枳实药材。
Objective To identify the origin of medicinal herbs of Aurantii Fructus Immaturus by electronic tongue technique. Methods The origin classification model was established by the response characteristics of the electronic tongue to samples of different producing areas. PCA and DFA were used to determine the origin of the test citrus aurantium and its application was confirmed by high performance liquid chromatography (HPLC). Results The commercially available citrus aurantium herbs are mainly divided into Jiangxi and Sichuan categories, electronic tongue on the four kinds of test citrus aurantium medicinal herbs to determine the results confirmed by high performance liquid chromatography. Conclusion Electronic tongue can effectively identify unknown origin citrus aurantium herbs.
