초록

석류(Punica granatum L.)는 생리활성이 강한 천연성분인 폴리페놀과 탄닌이 많이 함유되어 있어 예로부터 전통요법의 치료제로 사용되어 왔으며, 최근에는 석류의 phytoestrogen을 이용하여 갱년기 치료에 대한 연구가 활발히 진행중이다. 따라서 본 연구에서는 석류의 씨와 껍질의 ethanol 추출물과 석류 껍질 분획물을 이용하여 인위적으로 난소를 절제하여 폐경을 야기 시킨 흰쥐에서의 혈 중 지질 농도의 변화를 검토하였다. 그 결과 혈 중 total-cholesterol 및 triglyceride 농도에 있어서는 석류 ethanol추출물 투여에 의한 유의적인 효과는 없었으나, triglyceride의 경우 석류 껍질 추출물의 $200mg/kg{\cdot}bw/day$투여군에서는 OVX-control에 비하여 낮게 나타났다. 또한 혈 중 HDL-cholesterol농도는 석류씨와 껍질부분을 추출한 모든 실험군에서 동맥경화의 지표로서 관상성 심장질환에 대한 방어 작용을 가지고 있는 HDL-cholesterol 함량이 높게 나타났다. 특히 석류 껍질부분의 ethanol추출물의 경우 OVX-control에 비하여 유의적으로 나타나 갱년기장애로 인한 심혈관계 질환을 예방하는 천연 에스트로겐 대체 식품으로서의 귀추가 주목된다.

This study investigated the effects of Punica granatum L. (PG) ethanol extracts on serum lipid levels in ovariectomized rats. In order to elucidate the effects of PG ethanol extracts on the change of lipid concentration in rats, Sprague-Dawley female rats were randomly assigned to groups as follows: sham-operated rats (sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with ethanol extracts of PG seed at 50 mg/kg bw/day (OVX-PS50), ovariectomized rats supplemented with ethanol extracts of PG seed at 200 mg/kg bw/day (OVX-PS200), ovariectomized rats supplemented with ethanol extracts of PG peel at 50 mg/kg bw/day (OVX-PS50), ovariectomized rats supplemented with ethanol extracts of PG peel at 200 mg/kg bw/day (OVX-PP200). PG ethanol extracts were orally supplemented at the level of 1mL per day for 7 weeks. The body weight gain, food intake and food efficiency ratio were not significantly different between groups by t-test. The levels of total-cholesterol and triglyceride in serum were not changed by supplementation of PG ethanol extracts. The level of HDL-cholesterol on serum of the OVX-PS50 and OVX-PS200 groups were similar to the OVX-control group, but the OVX-PP50 and OVX-PP200 groups were higher than sham group. These results suggest that ethanol extracts of PG peel were more effected than those of PG seed.
