Abstract

The methanol extracts from different parts of Ixeris sonchifolia (Compositae) were evaluated for their total cholesterol lowering effect in mice. Mice were rendered hypercholesterolemic with 1% cholesterol and 0.5% cholic acid. Significant lowering in serum cholesterol was observed in mice with the methanol extract from leaves (MeOH-LF), whereas the methanol extract from roots (MeOH-RT) was devoid of this effect. In rats with cholesterol-induced hyperlipidemia MeOH-LF in a dose of 100mg/kg body weight caused significant decrease of total cholesterol, and the atherogenic index was also improved. On the other hand, total cholesterol in rats fed a stock diet was not affected by administration of the MeOH-LF. Thus, it is suggested that this MeOH-LF probably may increase the metabolic utilization only when fed with excess cholesterol.

고들빼기의 부위별 메탄을 엑스가 고콜레스테롤 생쥐의 혈청 콜레스테롤농도에 미치는 영향을 살펴보았다. 고콜레스테롤 생쥐는 식이에 1% 콜레스테롤과 0.5% 답즙산을 첨가하므로서 유도하였으며. 잎의 메탄을 엑스를 투여한 군은 대조군에 비해 혈청 콜레스테롤 농도를 현저히 감소시켰으나 뿌리의 경우에는 효과가 나타나지 않았다. 또한 잎의 메탄을 엑스는 고콜레스테롤 흰쥐에 대해서도 100mg/kg투여 용량에서 혈청 콜레스테롤 농도를 현저히 감소 시켰으며 동맥경화성 지표를 개선시켰다. 반면에, 정상흰쥐에 대해서는 효과가 나타나지 않았다. 이상과 같은 결과로 잎의 메탄을 엑스는 과잉의 콜레스테롤을 섭취하였을때 체내대사 이용도를 증가시키므로서 혈청콜레스테롤 농도를 감소시킨다고 생각된다.
