PURPOSE: An adipogenesis suppressing composition using extracts of alive condonopsis lanceolata trautv and steamed codonopsis lanceolata is provided to enhance adipogenesis suppressing effects. CONSTITUTION: An adipogenesis suppressing composition uses extracts of alive condonopsis lanceolata trautv and steamed codonopsis lanceolata. The extract is extracted by using water, alcohol or a mixture thereof as a solvent. The alcohol is C1-C4 low level alcohol. The low level alcohol is ethanol or methanol. The composition uses the organic solvent fraction which is obtained by additionally extracting the Condonopsis lanceolata Trautv as an organic solvent. The organic solvent is hexane, methylene chlororide, and ethyl acetate butanol. The health supplement for the local formation inhibition uses the alive Condonopsis lanceolata Trautv and steamed codonopsis lanceolata.본 발명은 식품소재인 더덕으로부터 추출물 및 분획물을 획득하고 지방전구세포인 3T3-L1 세포에 처리한 결과, 생더덕과 찐더덕을 처리했을 때 지방의 분화가 저해되는 것을 확인하고, 그에 따른 단백질과 mRNA의 발현 역시 저해되는 것을 확보하여 이를 토대로 본 발명을 완성하게 되었다.
