| 摘 要： | 目的:研究不同采收期中药金樱子气味指纹变化。方法:通过电子鼻检测不同采收期金樱子样品气味在传感器上的响应值,采用主成分分析法(PCA)、判别因子分析(DFA)进行分析,并进行统计质量控制分析(SQC)。结果:不同采收期金樱子样品经PCA和DFA分析后聚为两类,即1-6号样品聚为一类,7-10号样品聚为一类。结论:电子鼻结合PCA和DFA分析技术,气味可作为中药质量控制的指标。

| Abstract: | Objective: To determine the odor differences between Rosa laevigata samples of different harvest time.Methods: Evaporability composition of Rosa laevigata was sampled from headspace of emanating,and then response values was obtained.Principal component analysis(PCA) and discriminant factor analysis(DFA) are used to combine the optimum feature parameters,and statistical quality control analysis(SQC).Results: Rosa laevigata Samples of different harvest time clustered into 2 groups with PCA and DFA.Conclusion:... |
