Abstract: ABSTRACTOBJECTIVE To rapidly determine the content of bornyl acetate in amomum villosum by near?infrared spectros-copyNIRS.METHODS The content of bornyl acetate in 101 amomum villosum was determined by GC.The quantitative a-nalysis model of bornyl acetate in amomum villosum was established by collecting near?infrared spectra combined with partial least squaresPLS.RESULTS The correlation coefficientsR2 the root?mean?square error of calibrationRMSEC and the root?mean?square error of cross?validation RMSECV of the quantitative calibration model of bornyl acetate were 0.992 590.014 5 and 0.071 4the root?mean?square error of prediction RMSEP was 0.016 7.CONCLUSION NIRS is simple and accuratewhich can be used for rapid determination of bornyl acetate in amomum villosum.
