电子鼻在多基原郁金鉴定中的应用

Electronic Nose Used in Identifying for Curcumae Radix of Multiple Sources

目的:利用电子鼻技术实现多基原郁金的快速准确鉴定。方法:以检测器响应值为指标筛选样品的检测参数和金属传感器,通过主成分分析和辨别因子分析对特征数据进行统计学分析。结果:建立了多基原郁金的电子鼻检测方法,绘制了多基原郁金气味识别指纹图谱。结论:电子鼻可用于多基原郁金的鉴定,为多基原中药材的鉴定提供了新思路。

Objective： To identify fastly and accurately in Curcumae Radix of multiple sources by electronic nose. Method： The detective parameters of the samples and metal sensors were selected by detector response values and the characteristic datum were used for statistical analysis through principal component analysis and discrimental factor analysis. Result： The electronic nose detection method of Curcumae Radix were established and the odor identification fingerprint of Curcumae Radix were obtained. Conclusion： The method was used for identifying Curcumae Radix of multiple sources by electronic nose to provide a new idea for the identification of traditional Chinese medicine of multiple sources.
