Objective: To establish a near infrared spectroscopy method for the determination of polysaccharides in Polygonatum wine matrix extract. Method: The polysaccharide was measured by phenol-sulfuric acid method and the near-infrared spectroscopy of the Polygonatum wine matrix extract was collected by Fourier transform near infrared spectroscopy technology. Partial least square (PLS) was utilized to build the polysaccharide quantitative calibration model. Result: The results show that correlation coefficient (R)
internal cross-validation mean square error (RMSECV) were 0.970 3 and 0.771.External validation samples collected on-line were used to evaluate the quantitative models. The root mean square error of prediction (RMSEP) and the correlation coefficient of the true value and prediction were 0.624 and 0.969 2. Conclusion: The presented method is rapid
accurate and reliable
which can be used in practice to fast determine polysaccharide content in Polygonatum wine matrix extract.
