        Streptozotocin(STZ)을 45mg/kg.b.w의 용량으로 흰쥐의 미정맥에 투여 한 후 당뇨병이 유발된 당뇨 흰쥐에게 1일 1회 7일간 1,000mg/kg,b.w의 용량으로 황백에탄올 추출물을 투여 후 glucose 함량과 당대사에 관여하는 효소인 glucose-6-phosphatase(G-6-Pase), glucose-6-phosphate dehydrogenase(G-6-PDH, glucokinase(GK)활성과 glycogen 함량을 측정한 결과 황백 에탄올 추출물 투여군이 glucose 함량과 G-6-Pase 활성의 유의적인 감소를 나타내었으며 glycogen 함량과 G-6-PDH, GK의 활성은 유의적인 증가를 나타내었다. 이와 같이 황백 에탄올 추출물이 혈당강하 효과를 가졌다.

        This study was performed to investigate the antidiabetic study effect in ethanol extract of Ailanthicortex(A.C) radici in Streptozotocin(STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45㎎/㎏ dissolved in citrate buffer. The ethanol extract of A.C radici was orally administrated once a day for 7 days at a dose of 500㎎/㎏. The content of serum glucose, triglyceride(T.G), total cholesterol were significantly decreased in treated group compared to the those of STZ-control group. The content of hepatic glycogen and activity of glucokinase(GK) were significantly increased in treated group compared to the those of STZ-control group. but activity of glucose-6-phosphate dehydrogenase(G-6-PDH) was significantly increased. These results indicated that ethanol extract of A.C would have antidiabetic effect in STZ-induced diabetic rats.

        This study was done to investigate the antidiabetic effect of polygoni radix in Streptozotocin(STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose of 45mg/kg dissolved in citrate buffer. The ethanol extract of polygoni radix was orally administrated once a day for 7 days. The content of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in polygoni radix treated STZ-sample group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(Glucose-6-PDH), glucokinase were significantly increased, but activity of glucose-6-phoshatase was decreased in polygoni radix treated STZ-sample group compared to the those of STZ-control group. These results indicated that ethanol extract of polygoni radix would have antidiabetic effect in STZ-induced diabetic rats.

        This study was done to investigate the antidiabetic and antioxidant effects of Lycii fructus in Streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by intravenous injection of STZ at a dose 45mg/kg.b.w. dissolved in citrate buffer(pH4.5). The ethanol extract of Lycii fructus was orally administrated once a day for 7 days. The contents of serum glucose, total cholesterol were significantly decreaed (p<0.05) in Lycii fructus treated group compared to the those of STZ-control group, also content of Triglyceride (TG), Altherogenic index (AI) were decreased, but not statistically significant. But high density lipoprotein (HDL)-cholesterol and HDL-cholesterol/total cholesterol ratio (HTR) were increased in Lycii fructus treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6PDH), glutathione-s-transferase(GST), superoxide dismutase(SOD) were significantly increased(p<0.05), glucose-6-phos-phatase(G-6pase)was significantly decreased(p<0.05) and The glutathione(GSH), glucokinase(GK) were increased. But not statistically significant In Lycii fructus treated group compared to the those of STZ-control group These results indicated that ethanol extract of Lycii fructus would have antidiabetic and antioxidant effects in STZ-induced diabetic rats.

        약용 매화지의류인 Parmelia austrosinensis와 P. praesorediosa의 추출물로부터 α-glucosidase에 대한 저해작용을 확인하였다. 효소저해물질은 가열, 산, 알칼리 조건 및 수종의 가수분해효소에 대해 대단히 안정한 특성을 나타내었다. 부분정제된 효소저해물질은 α-glucosidase 이외에도 각종 이당류 분해효소, 특히 포유류와 사상균 유래의 효소류에 대해 강한 저해작용을 나타내었으며, 다당류 분해효소에 대해서는 glucoamylase를 제외하고는 대부분 매우 약한 저해활성을 나타내었다. 두 종의 매화지의 추출물로부터 부분정제한 α-glucosidase 저해물질은 HPLC 상에서도 거의 동일한 retention time을 나타내었다. 실험용 rat에 전분 또는 설탕과 함께 매화지의에서 추출한 α-glucosidase 저해물질을 경구 투여한 결과, 식후 30분경의 급격한 혈당상승을 억제하는 효과를 나타내었다.
