In this study, cosmetic materials were developed using a new method of making juice through the fermentation of raw natural materials with microorganisms in order to supplement the advantages and disadvantages of an organic solvent extraction method and a microbial fermentation method. The natural products were selected from two colors (red, green) of paprika known to be rich in various colors and vitamins. The microorganisms used for fermentation were fermented by inoculating paprika with lactic acid bacteria (Lactobacillus plantarum) having sugar-hydrolyzed ability. First, we investigated the changes of physiologically active substances of two kinds of paprika juice and two kinds of fermented paprika juice. Total phenols content and total flavonoids content were higher in the fermented paprika juice than in the paprika juice, and especially in the fermented red paprika juice. Free radical scavenging effect and lipid peroxidation inhibitory effect were also showed an excellent antioxidative effect on paprika fermented juice, among which the effect of red paprika fermentation juice was the highest. The expression of MMP-1 in fermented red paprika juice with high antioxidant activity was inhibited by concentration-dependent expression of MMP-1 mRNA and MMP-1 protein. In the glycation experiments with aging, the anti-glycation effect of fermented paprika juice was highly inhibited by the production of advanced glycation end-products (AGEs), which was closely related to the antioxidant effect. In addition, the activity of senescence-associated ${\beta}$-galactosidase (SA-${\beta}$-gal), an indicator of cell senescence, was measured using human dermal fibroblast (HDF). The results showed that the cell senescence was inhibited when the cells were treated with fermented paprika juice. In conclusion, fermented paprika juice using lactic acid bacteria showed better antioxidative and anti-aging effects than paprika juice. Among them, fermented red paprika juice has the best antioxidant and anti-aging effect and can be applied as natural new material of antioxidant and anti-aging.

Chinese radish juice(CRJ) was used as a culture medium for the production of Candida utilis ATCC 42416 biomass. Soluble solid and total sugar contents of Chinese radishes were in the range between 5.5 and $8.8^{\circ}$Brix and 3.5 and 6.5%, respectively. Since sugar in radishes are in readily usable forms, pretreatm ent procedures were not necessary after the extraction of juice from fresh radishes. In shake flask experimetns, C. utilis ATCC 42416 grew well in CRJ and completed growth in 24 hrs at $30^{\circ}C$ and 200 rpm. Maximum cell dry weight obtainable from a liter of CRJ(1.0% sugar $DCRJ{\times}5$) was 21.5g, when the yeast was grown on CRJ diluted 5 times or more with tap water to make sugar content to be eual to or less than 1.0%. Supplementation of 5-fold diluted CRJ with some nutrients did not greatly influence the growth rate, yeast biomass production, or cell protein content significantly, indicating that CRJ itself was a good substrate for the production of biomass by C. utilis ATCC 42416.

We investigated the effect of the cell-wall-degrading enzyme and its skin contact time on the brewing characteristics of Cheongsoo grape. The easy of juice extraction was excellent at the cell-wall-degrading enzyme and skin contact treatments, and the aroma was best after five days of skin contact treatment. Furthermore, the juice yields of the Chengsoo grape were more dramatically increased by the cell-wall-degrading enzyme and skin contact treatments than by the control. The data on the pH, total acidity, and soluble solids did not significantly differ among the treatments, and the pH range from 3.1 to 3.4; the total acidity from 0.5% to 0.6% (as tartaric acid); and the soluble solids, from 6.7 to 7.1 $^{\circ}Brix$. The alcohol content of cell-wall-degrading enzyme treatment was highest with 13.3%. The total polyphenol was gradually increased with the longer skin contact time, and was highest after 10 days of skin contact treatment, at 306.4 mg/L. The main organic acids detected in the Cheongsoo wine were malic and tartaric acid, and citric, succinic and lactic acid were also detected. Our results show that the cell-wall-degrading enzyme and skin contact treatments were better in terms of the easy of juice extraction and significantly increased the juice yield and the volatile compound of the Cheongsoo wine.

The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.

The purpose of this study was to search available resources for new natural colorants. The extraction efficiency of colorants from black cowpea seed coats and their storage stability were examined according to the various extraction and storage conditions in this study. The results obtained were as follows: the optical density (O.D.) values of the extracted colorants increased with increasing extract time and temperature. Extraction at pH 4 was seen to be the most efficient among the various pH conditions. The color of the extract solutions were seen to change with variation in pH, for example, anthocyanins display color changes from orange-red, to orange, to blue, to greenish-blue at pH 3.0, 4.0-6.0, 7.0 and 9.0-11.0, respectively. The color changes of the extract solutions over various storage periods were determined using UV/Vis spectra these color changes indicate characteristic absorption patterns and a discoloration index which indicates the rate of absorbance (532 nm/454 nm). Methionine addition influenced the storage stability of the colorant solutions and this addition led to better storage stability than non-addition. In paper chromatography of juice extracted colorant, a long stripe was seen on development. Among three colorants obtained via paper chromatography according to development rate, at least two different colorants were mixed indicated by the appearance, or not, of a shoulder at 552 nm depending on the extent of development.

In order to obtain functional materials from aloe callus, we cultured Aloe vera L. leaf on MS medium added 0.2 mg/L IAA, 0.3 mg/L kinetin and 100 mg/L grape or/and apple juice for 30 days. While a callus differentiation during callus culture did not show, the cultured leaves were uniquely released extracellular material into the agar plate. After cultivation for 18 days, the cultured leaf and agar were harvested for extraction a functional material. The materials extracted were measured on the amount of total phenols, flavonoids and polysaccharides and determined on the antioxidant and antimicrobial activity. In result, callus extracts of additive free (CT) and added apple juice (2T) had more amount of phenol compound ($659{\mu}g/mL$, $533{\mu}g/mL$) and flavonoid ($580{\mu}g/mL$, $501{\mu}g/mL$) than natural leaf (p: $525{\mu}g/mL$, f: $301{\mu}g/mL$). However, the extract of natural leaf had the better effect of lipid peroxidation and polysaccharide content than the culture extract. All samples extracted had same effect on the nitrite scavenging activity. On the other hand, only 2T extract showed excellent 72% nitric oxide scavenging activity. The agar extract was also confirmed to contain polyphenol compound and polysaccharide content that had antioxidant and antimicrobial activity partly.
