Natural Artemisia extraction was extracted from Artemisia component using diethyl ether as a solvent, and we tested various pharmacetical and chemical characteristics of this extract. Characteristic experiments to use natural Artemisia extract tested antimicrobial experiment using microbe in pharmacetical material, and tested dye experiment using fiber in chemical material. From the result of characteristics experiment, some conclusions are obtained as follow. From the result of extraction experiment, it obtained about 10.4%-Artemisia extraction ratio as semi-solid state, and after dried in freezing from Artemisia extract of semi-solid state, it obtained about 10%-Artemisia extraction ratio as solid state of dark blue-green color. From result of antimicrobial experiment of Artemisia extract, number of staphylococcus aureus (ATCC-01) and aspergillus niger (ATCC-02) in microbe decreased more and more according to time passage. This phenomenon showed that Artemisia extract influences to antimicrobial effect. From the result of dye experiment of Artemisia extract, it appeared in direction of dark blue-green color after dyed to use cotton and silk with fiber to control in pH 7.5. Specially the result which confirmed dye of fiber with optical electron microscope (OEM), we could know that it appears darker silk than cotton.

From the result of pharmacetical characteristics and analysis of Green-tea extract, it could obtain some conclusions as follows. The extract experiment of Green-tea appeared about 10%-extraction ratio as semi-solid state, and after dried in freezing from Green-tea extract of semi-solid state, it obtained about 65% Green-tea extract as solid state. In the results on antimicrobial experiment of Green-tea extract, number of S-typhimurium and fungus in microbe decreased more and more according to the time passage. This phenomenon could show that Green-tea extract keeps antimicrobial effect. In the results on antioxidation experiment of Green-tea extract, DPPH scavenging activity of free radical showed that Green-tea extract appears more remarkable reduction ability than reference samples. This phenomenon means that antioxidation of Green-tea extract appears higher than Vitamin-C and BHA sample. In the results on intrument analysis, the fatty and aromatic components of aniline, acetaldehyde, acetic acid, trichloroethylene, caffeine etcs from Green-tea extract was detected with GC/MS analysis and inorganic components of Ca, Mg, Cu, Mo, Sb, Ti etcs from Green-tea extract was detected with ICP/OES analysis.

From the experiment result on pharmacetical characteristics and analysis of Garlic extract, some conclusions were obtained as follows. From the results on extract experiment of Garlic, extraction ratio was about 6.0%, and after dried with dry oven from Garlic extract, it obtained about 50%-Garlic extract of solid state. From results on antimicrobial experiment of Garlic extract, number of staphylococcus and fungus in microbe decreased more and more according to time passage. This phenomenon showed that Garlic extract keeps antimicrobial effect. From results on antioxidation experiment of Garlic extract, DPPH scavenging activity of free radical showed that Garlic extract appears more remarkable reduction ability than reference samples. This phenomenon means that antioxidation of Garlic extract appears higher than Vitamin-C and BHA. From results on instrument analysis, inorganic components of K, Na, Ca, Si, Mg, Zn etcs from Garlic extract were detected with ICP/OES and the fatty and aromatic components of trimethyl sulfide, diallyl disulfide, diallyl trisulfide, 2-mercaptobenzothiazole etcs from Garlic extract were detected with GC/MS.

From experiment results on pharmacetical characteristics and analysis of Glycyrrhizin extract, some conclusions are obtained as follows. From results on extract experiment of Glycyrrhizin, it appeared about 8%-extraction ratio as semi-solid state, and after dried in freezing from Glycyrrhizin extract of semi-solid state, it obtained about 70%-Glycyrrhizin extract as solid state of yellow gold color. From results on antimicrobial experiment of Glycyrrhizin extract, number of S-typhimurium and Fungus in microbe decreased more and more according to time passage. This phenomenon shows that Glycyrrhizin extract keeps antimicrobial effect. From results on antioxidation experiment of Glycyrrhizin extract, DPPH scavenging activity of free radical shows that Glycyrrhizin extract appears more remarkable reduction ability than reference samples. This phenomenon means that antioxidation of Glycyrrhizin extract appears higher than Vitamin-C and BHA. From results on instrument analysis, the fatty and aromatic components of 2-pentanone, cyclohexasiloxane, tetrasiloxane, benzoquinoline-2-carboxylic acid etcs from Glycyrrhizin extract was detected with GC/MS and inorganic components of Ca, Mg, Ti, Zn, Fe etcs from Glycyrrhizin extract was detected with ICP/OES.

In this study, the biological activities of Glycyrrhiza uralensis were investigated, including antioxidative, fibrinolytic, thrombin inhibitory, and a-glucosidase inhibitory activity. The hot water extract of Glycyrrhiza uralensis was fractionated into hexane, $CHCl_3$, ethyl acetate, butanol, and water fractions, and each of these fractions were assayed individually. The water fraction showed the highest extraction yield of 19.45% (w/w). Using the DPPH method, the free radical scavenging activity was to be the strongest in the $CHCl_3$ fraction at 89.3%. Using the fibrin plate method, only the butanol fraction showed a substantial plasmin activity of 0.62 units/ml. In thrombin inhibitory activity tests, a 100-fold dilution of the ethyl acetate fraction showed the strongest activity of 46.9%. In the a-glucosidase inhibitory activity assay, a 100-fold dilution of the $CHCl_3$ fraction showed the strongest activity of 80.6%. In conclusion, the combined results of this study demonstrate that the extracts of Glycyrrhiza uralensis can be used as a material for the development of biofunctional foods for diabetics.

Panax ginseng C.A Meyer is frequently taken orally as a traditional herbal medicine in Asian countries. The major components of ginseng are ginsenoside, which are pharmaceutical activity. The six major ginsenosides, including Rb1, Rb2, Rc, Rd, Re and Rg1 account for 90% of total ginsenosides. Even though the minor ginsenosides, including Rg3, Rh2 and compound K has high pharmacetical activities, the price of minor ginsenosides is too high. Therefore we isolated the gypenoside V and made it converted to minor ginsenosides. In the plant Gynostemma pentaphyllum Makino, gypenosdie V was presented as dominant saponin (content about 2.4%), and was similar to protopanaxadol type ginsenosides such as ginsenoside Rb1. In this study, we confirmed that the coversion of gypenoside V to minor ginsenosides after using the various treatment such as heating, acid treatment, commercial edible enzyme, and lactobacillus. Consequently, we optimizied the transformation of gypenoside V to minor ginsenoside using Thin Layer Chromatography (TLC), High Performance Liquid Chromatography (HPLC), Time-of-flight Mass Spectrometry (LC/TOF/MS).
