Objective: This study was proceeded to determine to what extent the decoction recipes and distillation recipes extracted from the infusion of the apricot seed and other herbs respectively would produce an effect on the proliferation and the differentiation of Preadipocyte 3T3-L1 Model separated from C57BL/6 mouse. Method: Preadipocyte 3T3-L1 Model was formed from the fat tissue of the epididymis organ, which was removed from 4-week-old C57BL/6 mouse and then was treated with collagenase. Results: 1. Concerning the restraint effect of proliferation on Preadipocyte 3T3-L1 Model, the decoction recipes, in the state of low consistency, were proved to be more effective than the distillation recipes. 2. Concerning the restraint effect of differentiation on Preadipocyte 3T3-L1 Model, the decoction recipes were shown to be more effective.
