A method for determining the artificial bezoar powder in bezoar powder using near-infrared (NIR) diffuse reflectance spectrometry was proposed in the present paper. The method was based on support vector machine (SVM). The calibration set was set up by adding unequal artificial bezoar powder to the bezoar powder (content range: 0%-100% ) and collecting the NIR spectrum of the samples in the wave number range of 4000-10000 cm(-1). The processing algorithm was wavelet transform with first and second derivatives. A mathematical model with support vector machine was established. The model was checked with leave one method. The sum of the square of the relative prediction error was 0.00135. This method is reliable and can be used to control the quality of bezoar powder.
