Objectives : The aim of this study was to evaluate the efficacy of Aconiti Lateralis Preparata Radix (AP) and Acanthopanacis Cortex (AT) extracts in bone-derived adipocyte OP9 cell, osteoclast and osteoblast-like MG63 cells. Methods : MTT assay was used to evaluate the cytotoxicity of AP and AT extracts on OP9, osteoclast and MG63 cells. OP9 cells were treated with AP and AT, and the alterations in fat storage in the cells were determined by the Oil red O. To explain effects of RANKL-induced osteoclast differentiation in bone marrow macrophages, we performed the TRAP staining. The protein level of CAAAT/enhancer binding protein alpha ($C/EBP{\alpha}$) and peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$) as a adipocyte differentiation marker, and adiponectin was examined using western blot in differentiated OP9 cells. Effects of related genes were confirmed by luciferase assay using reporter assay. Results : AP and AT was not toxic on OP9 and MG63 cells, but AT was a little cytotoxic to osteoclast at the dose of $100{\mu}g/m{\ell}$. They could inhibit differentiation of OP9 cells and osteoclast with results of oil red O staining and TRAP staining. By western blot, AP and AT decreased the expression of $PPAR{\gamma}$ and $C/EBP{\alpha}$ which is the key transcription factor in adipogenesis and adiponectin secretion. AT also inhibited the BMP-4 activity in luciferase assay. AP also inhibited BMP-4 and Wnt3a activity, stimulated ER-${\beta}$ activity but inhibited androgen receptor activity. Conclusions : These results show AP and AT can be useful in osteoporosis and obesity via inhibition of osteoclast and adipocyte differentiation.
