Study of Radix Ginseng Quality Detecting MethodBased on Sensor Array Optimization
摘要
Abstract
Different from usual storage method,storage condition of Chinese medicine is specially installed. Tradi-tional Chinese medicine radix ginseng quality determination method using M.O.S sensor array optimization was stud-ied in this paper. Sensor array responses to ginseng samples under different storage time were measured. Sensor loading analysis results demonstrated that sensor array optimization improved principal component analysis( PCA) discrimination degree of ginseng samples in different quality. Non-linear stochastic resonance( SR) was utilized for optimized measurement data analysis. Cross correlation coefficient ( COE ) quantitatively discriminated all samples. Ginseng quality determination model Q=(COEmax-0.23)/0.02(R2=0.99026)was developed by linear fitting regression of COEmax values. Validating experiments results indicated that the developed model presented a quality predicting accuracy of 83.3％for ginseng sample. The proposed method is promising in the Chinese medicine quality rapid detection.关键词
