In order to improve the qualities of red ginseng extract and decrease precipitate formation in ginseng drink, red ginseng extract were hydrolyzed with ${\alpha}$-Amylase and characteristics of the hydrolyzed ginseng extract were investigated. 1.08% of isomaltose were produced and glucose content was increased from 2.83% to 11.03% in the hydrolyzed red ginseng extract. Total ginsenoside content of the hydrolyzed ginseng extract were decreased from 1,661 mg/100g extract to 1,389 mg/100g extract. The hydrolyzed ginseng extract enhanced the growth of Lactobacillus casei, Lactobacillus rhamnosus and Lactobacillus helveticus. Bitterness and astringency of the hydrolyzed ginseng extract were lower than those of the ginseng extract Precipitate formations in ginseng drink prepared with the hydrolyzed ginseng extract were significantly reduced in the storage conditions of 40$^{\circ}C$ for 4 weeks compared to those of control.

Effects of Panax ginseng were tested on morphine-and steroids-induced immunosuppression, focusing on mechanism and identification of active components. To investigate overall effects of morphine and ginseng total saponin (GTS) on immune system, body weight and lymphoid organ weight were measured. Morphine significantly reduced body weight, spleen/body weight, and thymus/body weight ratio. GTS, at 100mg/kg (oral), restored spleen/body weight ratio. Because morphine is known to increase corticosterone level, serum corticosterone level was measured by radioimmunoassay. Serum corticosterone was increased by morphine and it was restored to the control level by GTS 100mg/kg (oral). In vitro proliferation studies were also conducted to study the effects of ginseng on steroids-induced immunosuppression. While ginsenoside Rg$_1$ and ginseng alkaloids were effective on proliferation and dexamethasone-induced death of thymocytes, 50% ginseng ethanol extract and polysaccharides were effective on splenocytes. In vivo mprohine-induced apoptosis of thymus was partly protected by GTS.

Chemical composition was determined to evaluate the quality of Panel ginseng-leaf tea over green teas. Ginseng-leaf tea was shown to contain higher contents of soluble matter, ascorbic acid and lower contents of tannins, as compared to tea leaves. The profiles of ginsenoside and sugar of ginseng-leaf tea were noticeably different from those of ginseng roots and the sample maintained high levels of these components under the manufacturing process. Total unsaturated fatty acids and free amino acids were estimated to be decreased in ginseng-leaf tea as compared to those of ginseng leaves. The compositions of amino acids and minerals in ginseng-leaf tea were similar to those of tea leaves and glutamic acid, aspartic acid, leucine, calcium, potassium, sodium, and copper were found to be major components.

Glucosidic bonds at the C20 position of the sapogenins were hydrolyzed easily in the lower pH, higher temperatures and longer times to give prosapogenins and sugars. The glucosidic bond of saponin at the C3 of ginsenoside-Rb1, which is secondary carbon, was relatively stable due to the low electron density of -0.2. But the bond of saponin at the C20 position, which is tertiary carbon with the relatively high electron density of -0.3, was liable to be hydrolyzed even in weakly acidic solution by the increase of heating time. On the other hand, red ginseng contained 13.34 mg/g of citric acid, 8.78 mg/g of malonic acid, 3.70 mg/g of oxalic acid, 2.13 mg/g of malic acid and 0.44 mg/g of succinct acid. Ginseng saponins were very stable in ginseng extract neutralized with sodium carbonate or sodium bicarbonate corresponding to the equivalent amount of the total organic acid in the red ginseng.

This study was devised to obserL'e the inhibitory effects of 7 kinds of ginsenosides on a lipolytic action of Toxohormone-L. The ginsenosides used in this experiment were -Rbl, -Rbl, - Rc, - Re, - Rgl, and - Rg2 prepared from Korean red ginseng. Toxohormene-L was partially purified by centrifigation from the ascites fluids of Sarcoma-180 bearing mice. In vitro test showed that the inhibitory effect of - Rb2 on the lipolysis by Toxohormone-L was highest percent among other treatments at concentration of 100 $\mu\textrm{g}$/ml and 500 $\mu\textrm{g}$/ml of reaction mixture. And total inhibitory activity (units) of - Rb2 was also highest among other treatments at the same concentration. However, in vivo test, body weight gain of Sarcoma-180 bearing mice decreased significantly by administration of - Rg2 compared to those of the control or other ginsenosides treated groups.

A lot of individual ginseng plants were selected in the farmer's fields to develop new ginseng varieties with desirable traits. Among them, a promising line has been developed through comparative cultivation of several lines selected with pure line separation of local raced. It was then designated as "KC (denotes Korean Ginseng)" and tested in the regional yield and adaptation trials for 10 years. KG lines grew vigorously after 4 years of age. Especially, KG 102 line arson운 them showed traits of multiple and short stems. As for the root characters, the length of taproot of KG 101 line was longer than that of local race, Jakyung-jong, or other lines ailed the root weight of KG 102 line waIn 15 % higher than that of local race. In general, KG 101, KG 103, KG 104, and Hwangsauk-jong had good root shape. Total amount of ginsenosides of ginseng taproot was the highest in KG 103 line than in local race and other lines. In these studies, we, elected three superior lines, KG 101, KG 102, and KG 103, having characteristic of good root shape, high yield, and large amount of ginsenoside, respectively.

Panax ginseng, also called Asian or Korean ginseng, has long been traditionally used in Korea and China to treat various diseases. The major active ingredients of P. ginseng are ginsenosides, which have been shown to have a variety of therapeutic effects, including antioxidation, anti-inflammatory, vasorelaxation, antiallergic, antidiabetic, and anticancer. To date, approximately 40 ginsenoside components have been reported. Current research is concentrating on using a single ginseng compound, one of the ginsenosides, instead of the total ginseng compounds, to determine the mechanisms of ginseng and ginsenosides. Recent in vitro and in vivo results show that ginseng has beneficial effects on cardiac and vascular diseases through efficacy, including antioxidation, control of vasomotor function, modulation of ion channels and signal transduction, improvement of lipid profiles, adjustment of blood pressure, improvement in cardiac function, and reduction in platelet adhesion. This review aims to provide valuable information on the traditional uses of ginseng and ginsenosides, their therapeutic applications in animal models and humans, and the pharmacological action of ginseng and ginsenosides.

Fresh ginseng of same grade was stored under the 4$\pm$1$^{\circ}C$ and 87~92% RH for 10 weeks. During the storage, an aliquot amount of the ginseng was drawn, freeze dried and chemical constituents and physicochemical parameters were measured. After 10 weeks of storage drying rate and shrinkage of ginseng were 1520% and 9.04%, respectively, mold growth was seen at week 5 and observed for 51.2% of the ginseng week 10. Amylase activity level was elevated at the early stage of storage and decreased to 5% of initial value at week 5. At week 5, the elevated amylase activity was inconcomitant with the appearance of the mold growth. Crude protein contents were increased and decreased, respectively 5 week post storage. No significant changes in crude fat, crude fiber, ash, total sugar, n-butanol extract and ginsenoside were observed. The content of water-extractable substance showed maximum at week 7 to 8. The value of pH was slightly elevated and reducing sugar was increased during the storage. Key words Ginseng storage, physicochemical properties, drying rate, shrinkage, amylase activity.

In this study, we isolated ginseng crude saponin (GCS) from Korean red ginseng (KRG) and determined the ginsenoside content in it to investigate the physiological and pathological effects of GCS on acute pulmonary inflammation induced by intratracheal instillation of cigarette smoke condensates (CSC) and lipopolysaccharide (LPS) solution in BALB/c mice. GCS was orally administered at doses of 10 mg/kg and 25 mg/kg for 3 weeks. The recovery rate of GCS from KRG was 6.5 % and total ginsenosides from GCS was 1.13 %, and the content of Rb1 was the highest among them. Total inflammatory cells in the lung homogenates and bronchoalveolar lavage fluid (BALF) increased following intratracheal administration of CSC and LPS. However, GCS administration impaired this increase. Furthermore, it inhibited the increase in leukocytes in the blood, considerably decreased neutrophils in BALF, and declined infiltration of inflammatory cells and deposition of collagen in the tracheal and alveolar tissue. In this study, GCS was found to have a protective effect against acute pulmonary inflammation and it may be beneficial in preventing various respiratory diseases.
