The purpose of this study was to measure the antioxidant activity and bioactivity of black chokeberry (Aronia melanocarpa). The black chokeberry was known to contain many physiologically active substance, such as ascorbic acid, anthocyanin, quercetin. We extracted black chokeberry powder from four solvents such as chloroform:methanol(CM, 2:1, v/v), distilled water (DW), 70% ethanol, 70% methanol. After that, we determined anthocyanin, total phenol, flavonoid content, DPPH radical scavenging activity, ABTS radical scavenging activity, ferric reducing antioxidant power, reducing power and Nitrite scavenging activity of black chokeberry extracts and as results of comparing each extract. respectively. From the above results shows that antioxidant activity and bioactivity of black chokeberry extracts was the highest in 70% methanol (p<0.05). The results suggest that black chokeberry can be used as nutraceutical foods and natural antioxidant.

The objective of this study was to assess improvements caused by silk sericin extract in blood glucose and lipid concentrations in the sera of streptozotocin(STZ, 55㎎/㎏B.W., I.P. injection)-induced diabetic rats fed on experimental diets for 5 weeks. Serum concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride(TG) and phospholipids(PL) were remarkably higher in the diabetic group(group BSW) and STZ(I.P.)-plus-silk sericin extract group(group ESS) than in the control group(group CG, basal diet-plus-water). However, the serum concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG and PL were lower in the ESS group than in the BSW group, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the ESS group were higher than in the BSW group. The activities of alkaline phosphatase(ALP) and aminotransferase(AST, ALT) in serum were lower in the ESS group than in the diabetic BSW group. The results shown above suggested that silk sericin extract effectively improves blood glucose and lipid concentrations in the sera of STZ-induced diabetic rats.

이상지질혈증 흰쥐에 있어서, 누에로부터 효소 처리하여 추출한 세리신의 섭취가 혈청 지질대사 개선효과 및 지질대사 이상 등에 관여하는 지질성분 및 효소의 활성 변동을 검토하기 위하여 이상지질혈증 Sprague Dawley계 흰쥐 수컷을 사용하여 본 실험을 행하였다. 기본식이만을 섭취한 대조군인 BW군을 비롯한 이상지질혈증 유발군(HCW군), 이상지질혈증 유도에 세리신을 급여시킨 군(HCS군)을 5주간 실험 사육하였다. 혈청 총 콜레스테롤, 동맥경화지수, LDL-콜레스테롤, 중성지방, 인지질, 유리 콜레스테롤 농도, 콜레스테롤 에스테르 비 및 혈당 농도 등은 실크 세리신을 급여시킨 군(HCS군)에서 농도가 감소되는 것으로 나타났다. 한편, HDL-콜레스테롤 및 총 콜레스테롤에 대한 HDL-콜레스테롤 비 등은 세리신 섭취(HCS군)에 의해서 증가되는 것으로 나타났다. 혈청 중 alkaline phosphatase (ALP) 및 aminotransferase (AST & ALT)의 활성은 이상지질혈증을 유도 시킨 후 실크 세리신을 섭취시킴으로써 효소 활성이 억제되는 것으로 나타났다. 이상과 같은 결과에서, 실크 세리신이 흰쥐의 혈청 지질대사 이상 등에서 오는 이상지질혈증의 예방 및 개선에 효과가 있을 것으로 생각된다. The principal objective of this study was to investigate the effects of silkworm sericin extract supplementation on the improvement of lipid compositions, blood glucose levels and enzyme activities in the serum of dyslipidemic rats. The rats were fed the experimental diet for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL-cholesterol, triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester ratio and blood glucose in serum were higher in the dyslipidemic group (group HCW) and cholesterol-plus-silkworm sericin extract intake group (group HCS) than those in the control group (group BW, basal diet-plus-water). However, the concentrations of total cholesterol, atherosclerotic index, LDL-cholesterol, TG, PL, free cholesterol, cholesteryl ester ratio and blood glucose level in serum were lower in group HCS than those in group HCW. On the other hand, the HDL-cholesterol level and the ratio of HDL-cholesterol to total cholesterol in group HCS were higher than in group HCW. The activities of alkaline phosphatase (ALP) and aminotransferase (AST & ALT) in serum were lower in group HCS than in the dyslipidemic group HCW. From the above results, it was suggested that silkworm sericin extract intake was effective in the prevention and improvement of lipid components, blood glucose level and enzyme activities in the sera of dyslipidemic rats.
