Rapid Qualitative Identification of Medicinal Part of Commercially Available Panax notoginseng Powder Based on Near Infrared Spectroscopy
摘要
Abstract
To determine the medicinal part of commercially available Panax notoginseng powder using near infrared spectroscopy. Methods: After collecting the near-infrared spectra of Panax notoginseng taproot, rod and rhizome, the discriminant analysis method of the different medicinal parts of Panax notoginseng was established by using the method of principal component analysis and Mahalanobis distance. Results: In wavelength range of 4 400～ 4 800 cm-1,5 400～ 6 600 cm-1 and 7 800～ 10 000 cm-1,Panax notoginseng taproot, rod and rhizome were able to be distinguished. The accuracy rate of internal validation was 100％, 66％ and 75％, respectively. 25 batches of commercially available Panax notoginseng powder was identified, there were 22 batches of powder identified as a rhizome and three batches of powder identified as a mixture of rod and rhizome. Conclusion: It is feasible to identify the medicinal part of commercially available Panax notoginseng powder by near infrared spectroscopy technique,which extends the application function of near infrared on-line monitoring and supplement the limitation of traditional traits.关键词
