Quantitative Analysis on Extracts by Water and Ethanol in Rhizoma Dioscoreae by Near-Infrared Diffuse Reflection Spectroscopy

OBJECTIVE Rapid nondestructive determination of extracts by water and ethanol in Rhizoma Dioscoreae with near-infrared reflectance spectroscopy. METHODS Two quantitive models were built up with near-infrared diffuse reflectance spectroscopy. RESULTS The RMSEP in quantitative calibration model for extracts by water and ethanol were 1.26 and 0.084 9 respectively. CONCLUSION NIRS technique can dispose the samples without complicated pretreatment. You can achieve the results rapidly and correctly. It owns many remarkable advantages that cannot be displayed by traditional analysis methods. It is qualified to rapidly analyze traditional Chinese medicine(TCM) whose components are complex. NIRS can online control the quality in production process of TCM.
