Abstract: To establish evaluating the quality of Magnolia officinalis quickly and efficiently, this paper determined the quantification method of phenolic compound by using near infrared reflectance spectroscopy. Under the full wavelength, different mathematics and statistics were compared in the calibration. The statistics methods include partial least squares(PLS), modified PLS and principal component regression(PCR). The best mathematic method was3, 6, 6, 1, scatter correction method was transformation of standard normal variate(SNV)+detrending(D)orSNV and statistic method was modified PLS.The correlation coefficientof calibrationwas above 0.97.The correlation coefficientof exteriorcalibrationwas above 0.95. This indicates thatnearinfrared reflectance spectorscopy(NIRS)is comparable to chemical methods in both accuracy and prediction and is reliable in practical application.[Ch, 2 fig. 5 tab. 11 ref.]
