These studies were carried out to characterize the physiological functionalities of Codonopsis lanceolata, Cornus officinalis, and their mixtures. We investigated the antioxidative, fibrinolytic, and ${\alpha}$-glucosidase inhibitory activities of them. The antioxidative activities of Codonopsis lanceoiata and Cornus officinalis were 87% and 90%, respectively. Addition of salt to Codonopsis lanceolata and Cornus officinalis did not affect its antioxidative activities. In spite of fourfold addition of Codonopsis lanceolata to Cornus officinalis, the antioxidative activity was conserved at 90%. The fibrinolytic activities of Codonopsis lanceolata and Cornus officinalis were 0.78 plasmin unit/ml and 1.74 plasmin unit/ml, respectively. Addition of salt decreased the fibrinolytic activities of both Codonopsis lanceolata and Cornus officinalis. A mixture (3:1) of Codonopsis lanceolata and Cornus officinalis exhibited a 21% increase in activity. The ${\alpha}$-glucosidase inhibitory activities of Codonopsis ianceoiata and 100-fold diluted Cornus officinalis were 25% and 73%, respectively. The addition of salt to Codonopsis lanceolata and Cornus officinalis slightly decreased their ${\alpha}$-glucosidase inhibitory activities. According to the addition of Cornus officinalis to Codonopsis lanceoiata, the ${\alpha}$-glucosidase inhibitory activities of the resulting mixture were highly increased. We anticipate that these results will be used as basic data for the development of new bifunctional foods.

This study has been conducted to understand the relationships such as interspecific interactions between species and landscapes within and outside of agricultural land by identifying the flora features of Cornus officinalis farmlands in Gurye which designated as Korea's Important Agricultural Heritage System. For this, the flora of vascular plants was surveyed in every land uses of two representative districts. These two districts represent the own features of Cornus officinalis farming area which including land uses like forests(especially pine tree), valley, farmland(rice paddy, farms, Cornus officinalis farmland), and residence. Also differences in flora by stone wall's existence and Cornus officinalis's DBH were surveyed. As a result, Cornus officinalis farmlands showed the various vascular plants than the other land uses. According to the existence of stone wall in Cornus officinalis farmlands, there were no differences in appearance flora. But the flora in Cornus officinalis farmlands which have different Cornus officinalis' DBH(Divided into average over 15cm and under 8cm), various plants were showed in average over 15cm than average under 8cm. In conclusion, Cornus officinalis farmlands have been actively engaged in various types of land use and species exchanges, including forests, valleys, villages, and fields, and it has been confirmed that it acts as an ecological axis connecting forests to villages.

The antibacterial activity of the ethanol extract of Cornus officinalis against some bacteria related to foodborne illness and food spoilage was investigated. In the case of the disc diffusion assay, clear zones due to the inhibition of proliferation by Cornus officinalis extract were 8.5~18.3 mm at $4,000{\mu}g/disc$. The inhibitory effect of Cornus officinalis was as follows: Escherichia. coli ${\geq}$ Listeria monocytogenes ${\geq}$ E. coli O157:H7 > Bacillus cereus > Staphylococcus aureus > Pseudomonas aeruginosa > Salmonella typhimurium. In addition, the MIC of Cornus officinalis extract toward B. cereus was the lowest at 1,000 ppm. The extract inhibited the growth of E. coli, L. monocytogenes, E. coli O157:H7, and Bacillus cereus throughout the growth stage. However, the growth of P. aeruginosa, S. aureus, and S. typhimurium was only inhibited by the extract during the lag phase. The constituents of all cells tested were released, especially E. coli and E. coli O157:H7. Observation of the cells using SEM demonstrated a morphological change and disruption of cells in response to treatment with Cornus officinalis extract. Based on these findings, the ethanol extracts of Cornus officinalis showed strong antimicrobial activity against all tested bacteria, indicating that Cornus officinalis can be a useful natural antimicrobial reagent.

This investigation was performed to study the antioxidant activities of Cornus officinalis Sieb extracts and the effect of Cornus officinalis Sieb extracts on glucose, lipid metabolism in diabetic rats. DPPH free radical scavanging activity and superoxide anion radical scavenging of Cornus officinalis Sieb extracts were 94.7% and 92.1%, respectively. Streptozotocin (45 mg/kg body weight, i.p.) induced diabetic rats showed a significant increases of plasma glucose, triglyceride and total cholesterol, concomitantly significant decrease of plasma high density lipoprotein. Glutathione level were decrease in cytosol of liver, lung and brain tissue of rats. Lipid peroxide were increase in microsome of liver cells. Group 1 and 2 were treated with Cornus officinalis Sieb extracts 200 mg/kg body weight and 100 mg/kg body weight for 24 days, individually. Group 1 and 2 rats showed decreased plasma glucose, triglyceride, total cholesterol and lipid peroxide in microsome of liver, and increased plasma high density lipoprotein and glutathione in cytosol of liver, lung and brain. The result suggest that Cornus officinalis Sieb extracts may normalize the Impaired antioxiants status in streptozotocin induced diabetic rats. Cornus officinalis Sieb extracts were used to improve the imbalance between free radicals and antioxidant system due to the diabetes.

To evaluate the possibility as a natural preservative of Cornus officinalis seed extracts, we investigated the anti-microbial activity and preservation effect of cosmetics. Cornus officinalis seed extracted with 1,3-Butylene Glycol(1,3-BG) and Ethanol(EtOH). As a result, Cornus officinalis seed extracts showed anti-microbial activity at Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium acnes and Cornus officinalis seed 1,3-BG extracts(COS-A) showed $26.7{\pm}4.0mm$ clear zone at the $1000.0{\mu}l/ml$. Minimum inhibitory concentration of S. epidermidis was observed at Cornus officinalis seed EtOH extracts(COS-B) $25.0{\mu}l/ml$. The result of challenge test for preservation effect on cosmetics, S. aureus and S. epidermidis was 100% eliminated from emulsion containing COS-A and COS-B after 7 days. These results suggest that Cornus officinalis seed extracts may have possibility as the natural preservative instead of synthetic perservative on cosmetics.

The bacterial growth and pH of Cornus officinalis fermented with Lactobacillus rhamnosus during fermentation were evaluated. As the results, the number of the fermentation after fermentation always remained higher than 6 log CFU/mL and the pH of those ranged from 4 to 6. To evaluate the effect of Cornus officinalis fermented with Lactobacillus rhamnosus on hair growth promotion in C57BL/6 mice, Six weeks old male mice were divided into four groups including normal group (saline), negative control group (essence base), positive control group (minoxidil) and experimental group (Cornus officinalis and animal milk fermented with Lactobacillus rhamnosus mixed in negative control). And they were applied topically with test materials for 8 days. Hair regrowth effect in experimental group using gross and histological examination was higher than that in positive control group. Body weight and food intake of four groups didn't show significant difference. These results indicated that the Cornus officinalis fermented with Lactobacillus rhamnosus can be used practically for hair growth or prevention of hair loss.

This studies have been carried out to develop Korean traditional tea from the effects of Cornus officinalis and Lycium chinense and to study the developed tea on microbiological (Saccharomyces cerevisiae) and metaboilsm of experimental animals (Spraque-Duwely male rats 200g). On the microbiological study the yeast growth is increased with the increase of added Cornus officinalis or Lycium chinense and Lycium chinense increased the yeast growth more than Cornus officinalis, especially the synergistic effects are recognized on mixed extract of Lycium chinense and Cornus officinalis. The effects of Cornus officinalis, Lycium chinense or the mixed extract of both extract on liver damage caused by carbon tetrachloride were investigated in the case of animal test. The activities of GOT and GPT in serum are increased on control group compared to normal group but Lycium chinense group and group (which is administrated with the mixed extract of both ectract) decreased apparently the activities of GOT and GPT. The contents of Creatinine, BUN and Glucose in serum has no difference between normal and control group when the Cornus officinalis, Lycium chinense or mixed extract of both extracts were injected. Among them Lycium chinense group showed more normal value compared to Cornus officinalis and the mixture of both extract. The protective effect on rat liver damage caused by carbon tetrachloride is in order of Lycium chinense. The synergistic effects of the mixed extract on liver damage are proved to be better than Lycium chinense or Cornus officinalis singly.
