Abstract:
In this article, the method of quick and accurate identification ofAstragalus membranaceus (Fisch.) Bge. var.mongholicus (Bge.) Hsiao in different growth years by electronic nose (e-nose) technique and chemical analysis was developed. An e-nose was used to detect the odors ofA. membranaceus. var.mongholicus samples in two-growth-year, seven-growth year and more than a decade growth years for establishing the classification model of response characteristics. Principal component analysis (PCA) and discriminant factor analysis (DFA) were performed to differentiate theA. membranaceus. var.mongholicus samples in different growth years. PCA was performed to investigate the difference in the chemical composition and quality of different growth years inA. membranaceus. var.mongholicus samples. The results of PCA and DFA analyses for e-nose demonstrated that the samples ofA. membranaceus. var.mongholicus in different growth years could be distinguished obviously. The contents of chemical composition were similar in same growth years inA. membranaceus. var.mongholicus and different from different growth years. The results of chemical composition analysis indicated that the identification forA. membranaceus. var.mongholicus in different growth years was significant for the quality control. E-nose technique could identify the samples ofA. membranaceus. var.mongholicus in different growth years rapidly, sensitively and intactly, and could be applied for the quality control of traditional Chinese medicine.
