  • The extraction yield of Corni fructus was about 47.5% by extract apparatus. This study was done to investigate the antidiabetic and antioxidative effects of Corni fructus in Streptozotocin (STZ)-induced diabetic rats. The contents of serum glucose, total cholesterol and hepatic lipid peroxide, glutathione were significantly decreaed (p<0.05) in Corni fructus treated group compared to the those of STZ-control group, also content of triglyceride (TG), atherogenic index (AI) and activity of catalase were decreased, but not statistically significant. High density lipoprotein (HDL)-cholesterol and HDL-cholesterol/total cholesterol ratio (HTR) were increased in Corni fructus treated group compared to the those of STZ-control group. The activities of glutathione-S-transferase (GST) and superoxide dismutase (SOD) were significantly decreaed (p<0.05) in Corni fructus treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-phosphate dehydrogenase (G-6 PDH), glucokin-ase were significantly increased, but activity of glucose-Grphosphatase (G-6 Pase)was decreased in Corni fructus treated group compared to the those of STZ-control group. Therefore, these results indicated that ethanol extract of Corni fructus would have antidiabetic and antioxidative effects in STZ-induced diabetic rats.

  • To improve the functional and organoleptic properties of the fermented soymilk with Bacillus subtilis 2829PNU015 which has chungkukjang like flavor, functional materials from the edible plant extracts with well-known health promoting effects were examined by fibrinolytic activity and sensory evaluation. Among five samples such as Corni fructus, garlic, purple sweet potato, aged garlic, and pumpanini were tested, Corni fructus showed the highest fibrinolytic activity. The appearance and taste of the fermented soymilk (FS) was varied to the amount of Corni fructus added, and the highest acceptability of FS was observed from FS containing 1% Corni fructus extracts ($10^{\circ}$Brix) in it. Best way of applying Corni fructus to the fermented soymilk (FFS) was found to be incubating the mixture of soymilk and Corni fructus with Bacillus subtilis. FFS demonstrated dose dependent radical scavenging activities and these activities were found to be higher than those of FS at designated concentration.

  • This study investigated the effect of Corni Fructus (Cornus officinalis Sieb. et Zucc.) extract on blood glucose and insulin resistance in db/db mice. Seven weeks old male mice were divided into normal control group (NC), diabetic control group (DC) and Corni Fructus treated diabetic group (DCF). Over an 8-week experimental period, Corni Fructus extract was administered orally at 500 mg/kg BW/day. Corni Fructus inhibited increase in blood glucose level during the OGTT (oral glucose tolerance test). At 8 weeks after beginning of the experiment, blood glucose level in the DCF group was significantly lower (p<0.01) than the DC group. Final fasting serum glucose and triglyceride in the DCF group were significantly lower (p<0.05) than the DC group by 32% and 41% respectively. Serum insulin did not differ among the NC, DC and DCF groups. The mRNA expression of adiponectin, GLUT 4 and PPAR-$\gamma$ in adipose tissue in the DC group were significantly lower than the NC group and they were higher in the DCF group than the DC group by 76%, 130% (p<0.05) and 43%, respectively. In conclusion, these results indicated that Corni Fructus would have antidiabetic effects via improving insulin resistance in favor of higher glucose utilization and reducing blood glucose level in db/db mice.

  • This study investigated the antioxidative action of Corni Fructus aqueous extract on kidneys of diabetic mice. The electron donating abilities of Corni Fructus aqueous extract and its antioxidant activities (XO, SOD, CAT, GST, eNOS) in kidneys of C57BL/6 or db/db mice were evaluated. For in vivo study, seven week-old male mice were divided into normal control group (NC, C57BL/6 mice), diabetic control group (DC, db/db mice) and Corni Fructus (500 mg/kg/day for 8 weeks) treated diabetic group (DCF, db/db mice). The electron donating abilities of Corni Fructus aqueous extract exhibited 7%, 24.4%, and 42.7% at concentrations of 100, 500, and $1000\;{\mu}g/ml$, respectively. The activity of XO in the DCF group was significantly lower than the DC group by 35% (p < 0.05). The SOD activity was significantly higher in the DCF group than the DC group by 26% (p < 0.05). The activities of CAT and GST were lowered in the DCF group than the DC group by 26% (p < 0.05) and 7.6%, respectively. The mRNA expression of eNOS in kidneys was lower in the DCF group than the DC group by 24%. These results indicate that Corni Fructus reduced oxidation stress as evidenced by the restoration of the enzymatic antioxidative defense system in renal tissues of db/db mice. It is suggested that these antioxidative actions of Corni Fructus on renal tissues in db/db mice could contribute to its renoprotective effects on diabetic nephropathy.

  • In this study, analysis of active compounds that are believed to be highly relevant to antioxidant activity was carried out on the methanol extract and its solvent fractions of Corni fructus. The DPPH radical scavenging activity for the comparison of antioxidant activity was higher in order of aqueous fraction > methanol extract > ethyl acetate fraction > n-hexane fraction. It is similar to the order of total polyphenol contents in the samples. As a result of LC-MS analysis, phenolic acid compounds such as caffeic acid, gallic acid and chlorogenic acid and lognin, which is known as a representative active ingredient of Corni fructus, were identified as active compounds. And the antioxidative activity and the total polyphenol content of the extracts and solvent fractions were found to be related to the contents of the compounds. Particularly, it was confirmed that phenolic acid such as caffeic acid contributes to the antioxidative activity of the aqueous fraction of Corni fructus methanol extract.

  • This study investigated the effect of Corni Fructus(Cornus officinalis Sieb. et Zucc.) extract on hyperglycemia and renal function in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were divided into three groups including normal control(NC), diabetic control(DC), and diabetic treatment with Corni Fructus(DCF). Over a 4-week experimental period, Corni Fructus aqueous extract was administered orally at 500 mg/kg BW/day. The final fasting serum glucose, serum urea nitrogen, triglyceride, urinary total protein level, and relative weight of the left kidney in the DCF group were significantly lower than the DC group. Serum insulin level in the DCF group was higher than the DC group by 23%. The renal xanthine oxidase and superoxide dismutase activities in the DCF group were significantly lower than the DC group. The renal catalase activity in the DCF group was significantly higher than the DC group. In conclusion, these results indicated that Corni Fructus can reduce glucose level and prevent or retard the development of diabetic complication via its antioxidative effect and protecting against diabetic renal damage in streptozotocin-induced diabetic rats.
