초록

늙은 호박의 물 및 70% 에탄올 추출물에 대한 세포의 독성 및 지방생성에 미치는 영향을 조사하였다. 세포 생존율 측정에서 늙은 호박 추출물이 0.5-5 mg/mL의 농도일 때 물 및 에탄올 추출물 모두 세포의 생장에 영향을 미치지 않는 것으로 나타나 세포에 대한 독성이 없다고 판단되었다. 3T3-L1 지방세포의 지방축적에 미치는 영향을 1 mg/mL 농도로 조사하였을 때 에탄올 추출물은 지방축적을 저해 하였으나 물 추출물은 저해력이 없는 것으로 나타났다. 따라서 0.5-5 mg/mL로 농도를 달리하여 조사한 결과 두 추출물 모두 농도 의존적으로 지방축적을 저해하는 것으로 나타났으며 물 추출물과 에탄올 추출물 농도가 5 mg/mL 일 때 각가 85.22% 75.35%의 지방축적을 보였다. 따라서 본 실험에서는 늙은 호박의 물 및 70% 에탄올 추출물이 3T3-L1 지방세포의 분화를 억제하였으나 다른 많은 천연물에 비해 다소 높은 농도에서 효과가 나타났다. 또한 총 폴리페놀 함량조사 결과, 물 추출물에서 최대 $46.54{\pm}0.02$ mg을 함유한 것으로 나타나 늙은 호박은 제약 원료로는 제한점이 있으나 식품으로 꾸준히 섭취 할 경우 항비만 소재로서의 가능성이 있을 것으로 생각된다.

The anti-obesity activity of the $Cucubita$ $moschata$ Duch. extracts was investigated. The inhibitory effect on triglyceride accumulation was shown in 3T3-L1 preadipocyte. The lipid accumulation of the ethanol extract in 5 mg/mL concentration was shown to be 75.4%, where as that of water extract was shown to be 85.2%. The survival rate of the cell in the viability test was shown to be 86.5% in the 0.5-5 mg/mL concentration. Total polyphenol content was highest in the water extract($46.54{\pm}0.02$ mg). These results suggest that $Cucubita$ $moschata$ Duch. extracts have a potential as anti-obesity material by reducing the lipid accumulation.
