Abstract:
OBJECTIVE:To establish a method for rapid identification of genuine and spurious Panax notoginseng.METHODS:19 batches of samples including P.notoginseng of different origins and the common spurious P.notoginseng in China were collected.The infrared spectra of the samples were collected using near infrared spectrometer,then the spectra were pretreated by unitary vector plus second derivative method and the identification model was established by factorization method.RESULTS:The verification on 10 batches of commercial P.notoginseng samples showed that the established model can accurately identify the genuine and the spurious P.notoginseng.CONCLUSION:NIR spectrometry can quickly and accurately identify the quality of P.notoginseng,and it can be applied in rapid drug testing vehiches for extensive use.
