Objective: Rapid nondestructive determination of salvianolic acid B and tanshinone IIA in Radix Salviae Miltiorrhizae with near-infrared reflectance spectroscopy.
Method: A quantitive model was built up with near-infrared diffuse reflectance spectroscopy.
Results: The RMSEP in quantitative calibration model for salvianolic acid B and tanshinone IIA were 0.259 and 0.0232 respectively.
Conclusion: NIR 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 whose components are complex. NIR can control the quality in production process of traditional Chinese medicine.
