Objectives : The aim of this study was to examine effect of anti-oxidant and anti-inflammation activity of the Kyeongok-go with various processing methods that was manufactured by heating mantle. Methods : Commercial Kyeongok-go (K0) was purchased and Kyeongok-go with ginseng (K1), Kyeongok-go with black ginseng (BK), ginseng fermentation Kyeongok-go (KF), black ginseng fermentation Kyeongok-go (BKF) were manufactured by heating mantle. To examine anti-oxidant effect, DPPH radical and production of NO and ROS in RAW 264.74 cell were used. Furthermore, to determined anti-inflammation effect, measured pro-inflammatory mRNA such as NOS-II, COX-2, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ in RAW 264.74 cell treated with K0, K1, KF, BK, and BKF. Result : K1 scavenged DPPH radical effectively than K0. The most DPPH radical scavenging activity was BKF. In the RAW 264.74 cells stimulated with LPS, NO and ROS production were measured. As a results, K1 was decreased NO, ROS production compared with K0, and BKF was reduced similarly to cyclosporine A (positive control). Expression of pro-inflammatory mRNA such as NOS-II, COX-2, $IL-1{\beta}$, IL-6 showed a significant decrease in BK or BKF. But, there was no significant in expression of $TNF-{\alpha}$ in all extract treatmetn groups. Conclusions : According to the above results, it is considered that Kyeongok-go with fermented black ginseng (BKF) manufactured by heating mantle is effective material that have anti-inflammation and anti-oxidant activities. Our finding indicate that BKF may be an effective agent for anti-inflammation through anti-oxidant effect.

Fundamental data for new type of product development from Lycii fructus was experimentally determined. The chemical composition, and Hunter value changes, optimum extraction, volatile components of extract under different extraction conditions and heat treatment were mainly studied. Results are summarized as follows. The proximate compositions of dried Lycii fructus were water 21.8%, total sugar 27.6%, reducing sugar 15.2%, crude protein 14.29%, crude fat 5.65%, crude fiber 7.48%, and ash 7.98% in percent stale, respectively. Extracted yield on the basic of solid extract was getting increased when more solvent was used for extraction. The most recommendable extraction was 1 to 10 part of sample to solvent ratio. When water was employed as extraction solvent, the highest amount of solid extract was obtained. Extract of Lycii fructus in terms of yields and color was most acceptable when raw sample was treated 8 minute roasting at $180^{\circ}C$ and 60 minute heating at $120^{\circ}C$, respectively. Major volatile components of fresh Lycii fructus were to hexadecanoic acid, methyl linoleate, benzyl alcohol, dimetane benzene by GC/MS. By the roasting of raw sample, the compounds of 2-methyl-2buthenal, 1,4-dimethyl benzene, and benzyl alcohol were reduced. Wheras, methyl thiopropanol, benzene acetaldehyde and ethyl linoleate were slightly increased.

Hydrogen donating activities(HDA) of solvent extracts of Hololeion maximowiczii roots which were treated with freeze drying, hot air drying and hot air drying after steam blanching were investigated by the method of ${\alpha},{\alpha}'$-diphenyl-${\beta}$-picrylhydrazyl(DPPH). Hydrogen donating activity of hot air drying after steam blanching group showed the highest activity among three drying methods. Among the extracts of freeze dried root extracted with various solvents, color intensity at 420 nm of aqueous extract was highest, but hydrogen donating activity was shown in order of 50%, ethyl alcohol, methyl alcohol, water extracts. By heating the powder of freeze dried root at $100^{\circ}C$, color intensity of its water extract was decreased until 20 min, thereafter it was increased slowly but hydrogen donating activity was rapidly increased until 30 min. Hydrogen donating activity at the concentration of 6.05 mg/ml of 50% alcohol extract was similar to that of ${\alpha}-tocopherol$ at the concentration of $2{\times}10^{-4}M$. Comparison of hydrogen donating activity of the inner and outer solution after dialysis of water extract showed that the outer solution had a stronger hydrogen donating activity than those of the inner one.

This study investigated the possible improvement in the antioxidative status and quality characteristics of ready-to-eat (RTE) Samgyetang after adding various black garlic (BG) extracts. The antioxidant activity, total phenolic content (TPC), total flavonoid content (TFC), meat quality indexes, and lipid oxidation rates were measured after receiving one of five different treatments consisting of conventional Samgyetang broth as a negative control, raw garlic (RG) extract as a positive control, BG, oven-dried BG, and maltodextrin-encapsulated BG extract as treatments. Employing retort cooking, fat trimmed carcasses were added to the initially prepared broth together with a phenolic extract that was set at 5% (w/w). A significant intensification of red and yellow color was observed in breast and thigh meat treated with BG extracts, regardless of pretreatment, compared to the negative control and RG. The moisture percentage was affected by the addition of BG extracts, where the encapsulation group retained the highest water content after retorting. In terms of antioxidative status, maltodextrin-encapsulated BG extract was as effective as an oven-dried extract to scavenge free radicals and showed the highest score among samples (p<0.01). The concentration of TFC was found to be the highest and did not differ between encapsulation and oven-dried groups, followed by BG, RG, and the negative control. However, the addition of encapsulated BG extract was the most effective in delaying the formation of malondialdehyde among the samples. Therefore, pre-treatment of BG extract through encapsulation is recommended to develop a higher antioxidative status and quality characteristics of Samgyetang.

It was planned to evaluate the influence of Panax Ginseng upon hepatic DNA synthesis in mice by observing incorporation of $[^3H]$ thymidine into the tissue cells. Thirty male mice$(body\;weight:\;18{\sim}20\;g)$ were divided equally into the ginseng and the saline groups. Each animal of the ginseng and the saline groups received every day (subcutaneously) 0.05 m1/10 g body weight of ginseng extract (4mg of ginseng alcohol extract in 1 ml of saline) and the same amount of saline, respectively, for 5 days. On the 5th experimental day, all animals received $1\;{\mu}Ci/g$ body weight of $[^3H]$ thymidine intraperitoneally 2 hours after the last medication. Five animals, at a lime, of each group were sacrificed 1, 10, and 24 hours after thymidine administration, and their hepatic radioactivity was measured autoradiographically in terms of the % number of radioactive cells in 1,000 cell counts (Radioactive Index, R.I.). Following results were obtained: 1. The hepatic radioactive indices obtained from the saline group 1, 10, and 24 hour after $[^3H]$ thymidine administration were $3.23{\pm}0.23,\;5.20{\pm}0.21,\;and\;6.00{\pm}0.30\;(mean{\pm}S.D.)$, respectively. 2. The corresponding values obtained from the ginseng group $(4.22{\pm}0.33,\;6.32{\pm}0.32,\;and\;7.42{\pm}0.35)$ were significant higher than the values of the saline group. The inference from the above results was that the ginseng facilitated hepatic DNA synthesis.

The influence of high temperature storage on the chemical composition and color intensity of the concentrated red ginseng extract(RGE) was investigated. The concentrated RGE was prepared by extraction of red ginseng tails with water and concentrated under reduced pressure. Changes in free sugars, saponin patterns and brown color intensity were measured during 96 hours of heat treatment at various temperature. A decrease in the contents of glucose, fructose and sucrose was resulted as the brown color intensity increased during the storage. The sugar contents and color intensity showed rapid initial change followed by slowing down at higher temperature. A significant relationship was found between sugar content and browning rate. The saponin pattern measured by high performance liquid chromatography, particularly in the region of protopanaxtriol, was also affected significantly. The peak heights of ginsenoside -Re and $-Rg_1$ were decreased while those of ginsenoside $-Rg_2$ and -Rh group were increased.
