Abstract

In this work, the major flavonoid content of citrus peel ethanol extract and the changes in the serum lipid and body fat of high-fat-diet-fed rats were examined. The subjects were divided into four groups: the normal, control, O1 (0.1% citrus peel ethanol extract), and O5 (0.5% citrus peel ethanol extract) groups. The experimental groups (O1 and O5) were fed a high-fat diet mixed with 0.1 and 0.5% citrus peel ethanol extract, respectively, for 10 weeks. The results of the analysis showed that the main ingredients of the flavonoid in the citrus peel ethanol extract (60 brix) were $38.21{\pm}1.37$ mg/g hesperidin and $15.02{\pm}0.48$ mg/g narirutin. With regard to the changes in the serum total-cholesterol level, compared with the control group's $79.1{\pm}4.6$ mg/dL, the serum total-cholesterol levels of the O1 and O5 groups were significantly lowered to $64.6{\pm}5.4$ and $59.5{\pm}4.7$ mg/dL, respectively. As for the changes in the LDL-cholesterol level, compared with the control group's $18.4{\pm}3.7$ mg/dL, the LDL-cholesterol levels of the O1 and O5 groups were significantly lowered to $13.0{\pm}3.6$ and $13.0{\pm}1.9$ mg/dL, respectively. For the changes in the serum triglyceride level, compared with the control group's $74.5{\pm}13.2$ mg/dL, the serum triglyceride level of the O5 group was significantly lowered to $48.6{\pm}11.2$ mg/dL. Finally, with regard to the changes in body fat, compared with the control group, the 05 group showed a significant decrease. In conclusion, it was observed that citrus peel ethanol extract was effective in lowering the total-cholesterol, LDL-cholesterol, and triglyceride levels of high-fat-diet-fed rats.

고지방식이로 비만 및 고지혈이 유발된 실험동물에서 체중, 혈중지질, 체지방, 혈청생화학적 검사 및 장기무게를 측정하여 진피에탄올추출물 섭취로 인한 혈중지질 개선, 체지방 감량 및 시험물질의 간기능 및 장기무게 변화에 미치는 영향에 대해 조사하였다. 체중 및 사료이용효율은 고지방식이에 의해 대조군에서 증가현상을 보였으며, 진피 에탄올추출물 섭취군인 O1과 O5군에서 시험물질 섭취로 인한 체중증가량 감소와 식이효율 감소현상을 보였다. 혈청 생화학적 검사에서 고지방식이에 의해 혈중 ALT, AST, 총단백의 변화가 관찰되었으며, 진피에탄올추출물 섭취에 의해 정상군과 비슷한 수준으로 유지되는 것을 볼 수 있었다. 혈중 creatinine과 ${\gamma}$-GT의 경우 고지방식이 및 시험물질 섭취에 의한 변화는 관찰되지 않았다. 시험기간중 혈중지질 변화는 총 콜레스테롤, LDL-콜레스테롤, triglyceride, 동맥경화지수(AI) 모두 고지방식이에 의해 유의적인 증가현상을 보였으며, 진피에탄올 추출물 섭취로 인한 혈중지질 변화를 관찰할 수 있었다. 0.1% 진피에탄올추출물 섭취군인 O1에서는 대조군과 비교하여 총콜레스테롤과 동맥경화 지수를 유의한 수준으로 떨어뜨렸으며, 0.5% 진피에탄올추출물 섭취군인 O5에서는 총콜레스테롤 및 triglyceride 수준이 정상군 수준에 가까운 개선 효과를 나타내었고, LDL-콜레스테롤 및 동맥경화지수는 대조군과 비교하여 유의적인 개선효과를 보이는 것으로 나타났다. 고지방식이에 의한 체지방 변화는 정상군과 비교할 때 유의적인 증가현상을 보였으며, 0.1%, 0.5% 진피에탄올추출물 섭취로 인한 후복강 지방조직 및 부고환 지방조직에서는 유의적인 변화는 관찰되지 않았으나, 0.5% 진피에탄올 추출물에서 내장지방 무게는 유의적으로 감소하였다. 따라서 진피에탄올추출물 섭취에 의한 혈중지질 개선 및 체지방 개선 효과를 기대할 수 있을 것으로 사료된다.
