2Cl2 active parts, n-BuOH active parts, and polysaccharde. Results Compared with model group, the body weights in the volatile oil group, CH2Cl2 active parts, and n-BuOH active parts obviously increased (P < 0.05). And the levels of gastrin, serum amylase, and D-xylose were increased, but the levels of vasoactive intestinal peptide significantly decreased (P < 0.05). Conclusion Active parts except polysaccharide from Atractylodis Rhizoma stir-baked with bran show the functions of vigorating the spleen, and low polarity components are active."/> 2Cl2 active parts;n-BuOH active parts;polysaccharide;body weight;gastrin;vasoactive intestinal peptide;serum amylase;D-xylose"/>
