Rapid Analysis of the Quality of Formula Granule of Stir-baked Gardeniae Fructus Formula from Different Manufacturers by Near-infrared Spectroscopy

OBJECTIVE To analyse the quality of formula granule of stir-baked Gardeniae Fructus from different manufacturers. METHODS Integrating sphere diffuse full-wavelength scanning of samples from different manufacturers were measured by near-infrared spectroscopy. Mahalanobis distance was used to categoriz modeling and calculate the distance between different manufacturers. RESULTS The distances of formula granule of stir-baked Gardeniae Fructus formula produced by A, B and C were obviously different. CONCLUSION There are certain diversities of quality of formula granule of stir-baked Gardeniae Fructus from different manufacturers.
