Abstract

The effects of Aster scaber(Cham chyi) and Ixeris dentata(Sumbagui) of composite were studied on lipid metabolism in rats. Thirty rats were divided into five groups and fed diets containing 1% cholesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard(control group) for 4 weeks. For each experimental diet added was 5% plant powder or extract of the plant which was equivalent to 5% Plant powder by dry weight. The lipid components of serum were assayed. The concentration of the total cholesterol was significantly lower in Cham chyi, and Sumbagui powder and the extract groups of those powder than the control group. The concentration of HDL-cholesterol was significantly higher in rats fed Cham chyi and Sumbagui powder than the control group. The concentration of LDL, LDL-cholestrol, VLDL and chylomicron were comparatively lower in Cham chyi and Sumbagui powder groups than those in the control group. The concentration of seum triglyceride was lower in Cham chyi powder fed group than the control group.

국화과에 속하는 식용식물 중 참취 및 씀바귀가 고지혈증 횐쥐의 지질대사와 심혈관계에 미치는 영향을 구명하기 위하여 S.D.계 휜쥐에게 각각의 분말 5%와 그에 상당하는 열수 추출물을 급이하여 4주간 실험사육한 후 혈청 지질 성분을 분석하였다. 혈청 총 콜레스테롤 농도는 참취와 씀바귀 분말군 및 그 추출물군에서 유의한 저하 효과를 나타내었다. HDL-콜레스테롤 농도는 참취 분말, 씀바귀 분말군에서 유의하게 높았고, LDL, VLDL 및 chylomicron 농도는 참취, 씀바귀 분말 급이군이 대조군에 비하여 유의하게 낮았다. 혈청 중중성지질 농도와 인지질의 농도는 참취 분말 급이군이 가장 낮았다. 이상의 결과를 종합하여 볼 때 참취와 씀바귀의 섭취는 고지혈증의 치료나 예방에 효과가 있을 것으로 생각되며 참취와 씀바귀의 섬유소 뿐만 아니라 그 열수 추출물도 지질대사를 개선시키는 것으로 나타 나 이의 성분과 구조에 대한 더 많은 연구가 요구된다.
