Studies were carried out to clarify the effect of ginsenoside-Rbl -Rbr and acid hydrolyzatps of ginsenoside-Rbl, -Rb2 (HRbl, HRbf) on lipolysis and lipogenesis induced by epinephrine, glucagon, ACTH (adrenocorticotrophic hormone), TSH (thyroid-stimulating hormone) and insulin in rat adipose tissilr. HRbl , HRb2 slightly inhibited lipolysis induced by epinephine. glucagon and TSH. ACTH-induced lipolysis in fat tissue slices was significantly inhibited by ginsenoside -Rbl, -Rb2, HRbl and HRb2, particulary HRb2. None of ginsenoside-Rbl, -Rb2, HRbl and HRb2 accelerated insulin-stimulated lipogenesis in fat calls. Among ginseng products, extract powder (freeze dried), extract powder (spray dried), red ginseng powder inhibited ACTH-induced lipolysis in adipose tissue slices, but red ginseng extract not affect them.

Chemical changes in components of ginseng roots by heat treatment were observed. We have let the roots of fresh ginseng, of steamed ginseng and the water soluble parts obtained from preparing steamed one be subject to our research. Acids, bases, neutral substances and genins from each one of the above came up to 12 fractions. Having the fractions through column chromatography and TLC test thereafter, we determined the Rf values of each spots presented. Among so many similar values of them, 15 spots of heterogenous component in the fresh ginseng and 6 spots in the steamed one, and 10 spots in that of water soluble parts wre detected. Considering this data obtained, we can assume that partialor all of some components of fresh ginseng might be passed into water parts while preparing steamed ginseng from fresh ones and also some components of the later (fresh ginseng) might have been converted into other substances while being heated.

This study was conducted to produce a new red ginseng by steaming ginseng using a new pre-treatment method, so as to develop ginseng products with improved flavor and thereby expand ginseng's consumer base. The color parameters (Hunter value), free sugar contents, and ginsenoside contents of the powder from the dried red ginseng, and the sensory test of the semi-dried red ginseng and the decoction from the dried red ginseng, were measured to investigate the effect of acid (ascorbic acid or citric acid) impregnation pre-treatment on red ginseng. The powder from the acid-pretreated red ginseng became lighter and more yellow than the red ginseng that was not pre-treated, but the redness (avalue) of the powder from the acid-pre-treated red ginseng increased. The ginsenoside contents of $Rg_2+Rh_1$ and $Rg_3$ increased with the acid treatment. There was a significant difference in the color and sweetness of the semi-dried acidtreated and non-treated red ginsengs in the sensory test. As the results of the sensory test were expressed in the hedonic scale, however, there were significant differences in the degrees of bitterness, astringency, sourness, odor, and color of the red ginseng decollation. Especially, the acid-treated red ginseng extract tasted less bitter, which shows the potential of new red ginseng products with improved ginseng flavor.

Cornus fructus has been used as a tonic, astringent, and haemostatic agent in Korea, China, and Japan. In this study, the fruit of Cornus officinalis was treated with different osmotic pressures, pH values, heat, and ethanol percentages in order to establish optimum extraction conditions for gallic acid, an example of a hydrolyzable tannin. The extract was analyzed by HPLC and LC-MS/MS to identify the gallic acid. As a result, the highest extraction rate of gallic acid (1.57 mg/g) occurred when the Cornus fructus was extracted with 100% ethanol for 1 hr at $80^{\circ}C$. Also, when it was treated with 70% ethanol for 24 and 48 hr, contents of gallic acid were 1.35 and 1.50 mg/g, respectively.

We evaluated the anti-arthritic effect of a new diet-supplement product containing red ginseng, glucosamine, shark cartilage, ascorbic acid and manganese chloride for the relieving arthritic symptoms. Anti-inflammatory activities of the aqueous extract of red ginseng (250 and 500 mg/kg), glucosamine (240 mg/kg) and shark cartilage (240 mg/kg) were tested individually on vascular permeability and carrageenan-induced paw edema. Glucosamine and shark cartilage showed the inhibition of vascular permeability by 29.6 and 32.9%, respectively. Red ginseng (500 mg/kg) and shark cartilage showed the inhibition of carrageenan-induced paw edema at 0.5, 1, 2 and 3 hr. The supplement (red ginseng mixture: RGM) composed of red ginseng (43.5%), glucosamine (25.0%), shark cartilage (25.0%), ascorbic acid (5.0%) and manganese chloride (1.5%) was prepared and its inhibitory activities including vascular permeability and carrageenan-induced paw edema were comparable to anti-inflammatory drugs such as diclofenac and ibuprofen. It was also tested on adjuvant-induced arthritis in rats as one of chronic arthritic tests and Randall-Selitto assay as an analgesic test. RGM showed the inhibition against the swelling of rat paws induced by Mycobacterium tuberculosis at a dose of 1,500 mg/kg. Determination of cytokines of the sera sampled from arthritis-induced animals indicated that RGM increased the levels of $interferon-{\gamma}$ and interleukin-6, representing the immunostimulatory effect by red ginseng. RGM treatment moderately reduced the production of NO in RAW 264.7 cells in a dose-dependent manner. Taken together, these results support that RGM can be applicable for the improvement of arthritic as a new diet-supplement.

The purpose of the present study was to find the preferences of college students and to understand trends in their consumption patterns. This survey was conducted using a questionnaire containing 50 questions answered by 614 sudients of 4 universities in Daejeon and Seoul and the following result were obtained . 1. The majority of students favored coffee, yulmy tea, ginseng tea, and lllack tea in decreasing order. Only 49.0% of the students believe that ginseng was beneficial to the human life as a health, fond . 2. 54% of the students had experience in taking fresh ginseng and 68% had used in white ginseng. 3. Their expectations for the efficacy of ginseng were as remedies for hang-over syndrom, high blood pressure, heart trouble, liver trouble, and gastronic trouble, in decreasing order. 4. Most of the students took soup made by adding ginseng to chicken broth (SamGyetang) when taken ginseng. 5. The percent of students who had taken coffee was 97.7%, whereas only 48.3% had used processed ginseng products. The female students especially disliked ginseng tea. 6. The preferences of the students indicate that the likelihood that they will be major consumers of ginseng in the future is very low.

Lately, the Korean ginseng was confronted with the sale crisis in world markets from the various circumstance. One of important difficulties is overspreading of Korean ginseng imitative in foreign markets. In Korean markets also, chinese ginseng was imported illegally and manufactured as Korean ginseng, which was resulted inthe damage of Korean ginseng brand. The most essential problem is misunderstanding of Korean ginseng 。 s information in the foreigner. In this paper, we developed a genuine guarantee system to identify the true Korean ginseng through internet and geographic cording system of Korean ginseng products. This system can be applied to the enforcement of Korean ginseng sale to international markets.

Traditional medicinal practices have used natural products such as adaptogens to treat inflammatory, autoimmune, neurodegenerative, bacterial, and viral diseases since the early days of civilization. Panax ginseng Myer is a common herb used in East Asian countries for millennia, especially in Korea, China, and Japan. Numerous studies indicate that ginseng can modulate the immune system and thereby prevent diseases. Although the human immune system comprises many different types of cells, multiple studies suggest that each type of immune cell can be controlled or stimulated by ginseng or its derivatives. Provisional lists of ginseng's potential for use against viruses, bacteria, and other microorganisms suggest it may prove to be a valuable pharmaceutical resource, particularly if higher-quality evidence can be found. Here, we reviewed the role of ginseng as an immune-modulating agent in attempt to provide a valuable starting point for future studies on the herb and the human immune system.
