Objective:To determine chlorogenic acid of honeysuckle rapidly by near-infrared spectroscopy and data analysis software.Method:HPLC was used as a reference method to determine the content of chlorogenic acid in honeysuckle.Multivariate calibration model based on PLS algorithm wasdeveloped to correlate the spectra and the corresponding values determined by the reference method.Result:The correlation coefficients(R2)
the root-mean-square error of cross-validation(RMSECV) and the root-mean-square error of calibration(RMSEC) of the cal-ibration model for chlorogenic acid were 0.993
0.380 and 0.158
respectively;the root-mean-square error of pre-diction(RMSEP) and the average rate of recovery were 0.170 and 101.78%.Conclusion:The method is fast、con-venient、accurate and lossless.The correction model could be used to predict chlorogenic acid of honeysuckle rapidly.
