Objective: To conduct qualitative identification analysis of different Forsythia Fructus with use of near infrared spectroscopy combined with discriminant analysis method. Method: Near infrared spectrograms of different Forsythia Fructus were collected

then multiplicative scatter correction method (MSC) and Savitzky-Golay (SG) smoothing method were used for spectral preprocessing. Qualitative analysis model was established under the optimal modeling wave band of 4065.57-8350.90 cm-1 and optimal number (10) for principal components

and then this model was validated with unknown samples. Result: The classification results of the qualitative model were consistent with the actual conditions

and the validation results were also satisfactory. Conclusion: This method is simple

rapid

accurate

and non-polluting

with great significance for resources saving and efficient use of energy during the quality inspection in Chinese herbs

tobacco and other industries.
