title: [Study on evaluating quality of analgini powder pharmaceuticals by near infrared reflectance spectroscopy].
abstract: The possibility of using near-infrared reflectance spectroscopy for the evaluating quality of analgini powder pharmaceuticals was investigated. We used the multivariate statistical classification technique to identify true, poor and false phamaceuticals of analgini from their first derivative spectra successfully. The results are satisfactory.
