【Abstract】 The possibillty of using near infrared refiectance spectroscopy for the qual ity confrol of metronidazolum pharmaceuticals was investigat ed. We used the multivariate staristical classify techntrie (hierachical and stepwise analysis, principal component analysis and stepwise disdrindnant analisis) to identify true, poor and false phamacencicals of metronidazolum from their first derirative spectra succesifuly The result are satisfacory.更多还原
