Geographical origin identification and quantitative calibration analysis of Polygonum perfoliatum L. by near infrared spectroscopy
Rapid near infrared (NIR) spectroscopic analysis models were developed to distinguish the geographical origin and determine the content of Polygonum perfoliatum L. The spectra of 94 samples of differing origin were recorded using two NIR instruments (Antaris II and Nicolet 6700). The spectral pretreatment methods used were the first-derivative (FD) and the standard normal variate correction (SN...

15 صفحه اولDiscrimination and Content Analysis of Fritillaria Using Near Infrared Spectroscopy
Fritillaria is a traditional Chinese herbal medicine which can be used to moisten the lungs. The objective of this study is to develop simple, accurate, and solvent-free methods to discriminate and quantify Fritillaria herbs from seven different origins. Near infrared spectroscopy (NIRS) methods are established for the rapid discrimination of seven different Fritillaria samples and quantitative...
