Objective: To investigate the effects of wheat bran in different quality on the appearance and intrinsic quality of Atractylodes fried by wheat bran

and to provide a scientific basis for the quality standard of wheat bran. Method: Using a visual comparison and high performance liquid chromatography (HPLC) to observe the appearance and determine the content of atractylone

atractlenolide Ⅰ

atractlenolide Ⅱ

atractlenolide Ⅲ of Atractylodes fried by different particle size

water content of wheat bran and honey bran. Result: The smaller the particle size

the higher the water content of the wheat bran

the worse the appearance of the processed products

and also the intrinsic quality is worse;the color of products processed by honey bran was brighter than products processed by ordinary bran

and the intrinsic quality is better. Conclusion: The particle size of wheat bran should be greater than 40 meshes

the water content should be less than 10% when Atractylodes fried with wheat bran

and then processed with honey when Atractylodes fried with wheat bran. If conditions permitted

it is recommended to use honey bran. Quality control of the wheat bran has a great significance to improve the quality of processed Atractylode.
