초록

본 연구에서는 울금의 메탄올 추출물을 제조하고 3T3-L1 지방세포 모델을 이용하여 세포 수준에서 울금 인조쌀의 지방구 형성 조절을 통한 지질축적 억제능을 평가하였다. 더 나아가 C57BL/6J 마우스에 고지방식이와 함께 인조쌀, 울금 추출물이 첨가된 인조쌀을 공급하였을 때 체중과 지질대사의 변화를 관찰하였다. 세포 실험의 결과로부터 울금 메탄올 추출물을 처리한 후 $20{\mu}g/mL$의 농도에서 유의적인 지방구형성 억제를 관찰하였다. 동물 실험에서는 식이효율을 측정한 결과 인조쌀을 섭취한 군에서 그 효율이 낮아졌으며, 특히 울금 인조쌀을 섭취한 군에서 유의적으로 감소하였다. 부고환 지방 무게는 인조쌀 섭취군에서는 고지방섭취군과 차이를 보이지 않았지만, 울금 인조쌀을 섭취한 군에서는 유의적으로 낮아졌다. 혈청 지질 수준은 인조쌀군과 울금 인조쌀군 모두 고지방식이군에 비하여 개선되는 결과를 보였다. 혈청 중성지방은 인조쌀군과 울금 인조쌀군 모두유의적으로 낮아졌으며, 혈청 콜레스테롤 함량은 고지방식이군에 비해 인조쌀군에서 감소하는 경향을 보였고 울금 인조쌀군에서는 유의적으로 감소되었다. 이러한 결과를 통해 울금 이 첨가된 인조쌀에 다량 함유된 식이섬유소와 여러 생리활성물질이 지질대사를 개선시키고 지방 축적을 억제하여 일상식을 통한 체내 지질 수준 개선 효과를 기대해 볼 수 있을 것이라 사료된다.

; This study investigated the improvement effects of artificial rice containing Curcuma longa L. on lipid parameters in 3T3-L1 cells and C57BL/6J mice. Mice were divided into four groups, normal diet group (ND), high-fat diet group (HD), 20% artificial group (A20), and 20% Curcuma longa L. artificial rice group (C20), for 14 weeks. Adipogenesis was significantly suppressed compared with non-treated control at a concentration of $20{\mu}g/mL$. After the animal experiment, food efficiency ratio was elevated in the experimental group due to high-fat diet, whereas it was reduced in the A20 group and significantly reduced in the C20 group. Epididymal fat pad weight was significantly diminished in the C20 group. In addition, serum triglycerides were significantly reduced in the A20 and C20 groups compared to the HD group. Moreover, serum cholesterol level tended to decrease in the A20 group and significantly decreased in the C20 group compared with the HD group. According to these results, we can know that Curcuma longa L.-containing artificial rice has an improvement effect on lipid metabolism.
