Abstract

This study was performed to develop new anti-obesity agents from medicinal plants for functional food industry. We prepared lipase inhibitor-containing ethanol extracts from Desmodium oxyphyllu DC. and its nutritional characteristics, stability of temperature and pH and physiological functionalities were investigated. Crude lipid content and curde protein content of ethanol extract from Desmodium oxyphyllum DC. were 26.5% and 5.7%, respectively and its asparagine content was 4,860 mg/100 g, dry basis. The ethanol extracts were also stable from pH 3.0 to pH 9.0 and below $80^{\circ}C$. The ethanol extract were showed high lipase inhibitory activity of 74.2% and acetylcholinesterase inhibitory activity of 68.4%.

천연물로부터 lipase 저해물질을 개발하여 기능성 식품 산업에 응용하고자 lipase 저해 활성이 우수하여 전보에서 최종 선발된 도둑놈의 갈고리(Desmodium oxyphyllum DC.) 에탄올 추출물의 영양성분, 온도, pH 안정성과 생리기능성 등을 측정하였다. Lipase 저해물질을 함유한 도둑놈의 갈고리 에탄올 추출물의 지질과 단백질 함량은 각각 26.5%와 5.7%이었고 유리아미노산으로 asparagine과 tryptophan 함량이 각각 4,860 mg/건조중량 100 g, 1,209 mg/건조중량 100 g으로 물 추출물보다 높았다. 또한, 도둑놈 갈고리의 에탄올 추출물은 pH 3.0~9.0, $80^{\circ}C$ 이하에서 비교적 안정하였고, 이에 대한 생리 기능성을 측정한 결과, lipase 저해 활성은 74.2%, 항 치매성 Acetylcholinesterase 저해 활성은 68.4%로 비교적 높은 활성을 나타내었다.
