Abstract:
Objective:To quantitatively analyze the water content in Pinellia ternata by near-infrared spectroscopy to plant seed-ling cultivation and determine the quality of Pinellia ternata.Methods: Near-infrared spectroscopy was used to establish the model , and the moisture was measured by the drying method .The quantitative model was established by partial least squares method .Results:The quantitative model was established with the correlation coefficient of 0.9903 and the RMSECV of 0.205.The internal cross valida-tion and the external verification were both less than 1.0％.Conclusion:The established model can accurately predict the content of water in Pinellia ternata, which can be used for planting seedling cultivation , medicine storage management and quality control .
