RESUMO
We previously proposed the processing theory of "reducing ketone and dryness, and increasing ester and effect" for bran-fried atractylodes, and made a preliminary study. To further verify the science and rationality of the theory, we determined the changes in the content of atractylenolide I, II, III and atractylon in atractylodes after and before being fried with bran, in order to compare the effect of raw and bran-fried atractylodes on the water intake and urination in rats in this study. The effect of raw and bran-fried atractylodes on the content of four gastrointestinal hormones and two neurotransmitters in serum was observed in an attempt to verify the science and rationality the processing theory of "reducing ketone and dryness, and increasing ester and effect" for bran-fried atractylodes.
