This study was conducted to investigate the effects of ginseng and Schizandra chinensis on the quality characteristics of kimchi stored for 40 days at $4^{\circ}C$ after kimchi was fermented for 1 day at $25^{\circ}C$. pH and reducing sugar of GS(Kimchi added with extract powder of fine ginseng root and Schizandra chinensis juice) were the highest in the early part of storage but pH and reducing sugar of G(Kimchi added with extract powder of fine ginseng root) were the highest from 11th storage day. Acidity and $CO_2$ content of GS were the highest during storage period. The $CO_2$ content of GS was the highest significantly and the $CO_2$ content of C(Control) was the lowest significantly. When the hardness was measured, G was the hardest and there were no significant difference between C and GS. Total cells and lactic acid bacteria were increased rapidly at initial fermentation and GS was the highest of 3 samples from 6th storage day. The result of sensory evaluation showed that G was lower in sourness and higher in hardness than C and GS. Ginseng flavor had no significant differences between G and GS. And G was higher than GS in bitter taste. Consumer Acceptance test showed that consumer prefered C and GS to G. Considering all results, it can be concluded that addition of Schizandra chinensis juice to kimchi decreases the bitter taste of ginseng and increasing consumer preference.

Extruded ginseng was manufactured using twin-screw extruder under 300 rpm screw speed, 21 kg/hr feed rate, $80-150^{\circ}C$ extrusion temperature, and by addition of water (12.1-30.6%). Extraction yield and contents of total carbohydrate and uronic acid in extruded ginseng at room temperature extraction (RT) increased with increasing extrusion temperature, whereas those of boiling temperature extracts (BT) were not affected by increasing extrusion temperature. Contents of nonstarch polysaccharide (NSP) in RT and BT extracts increased 340 and 142%, respectively, compared to that of raw ginseng. Main sugar compositions of NSP in RT and BT extracts were arabinose, galactose, and glucose. Extraction yields of total and crude saponins in extruded ginseng at optimize extrusion condition were higher than that of raw ginseng. In RT extracts, molecular weights of polysaccharides from raw were higher than that of extruded ginseng polymer, whereas in BT extracts molecular weights of polysaccharides from extruded ginseng were higher than those of raw ginseng polysaccharides.

The studies on the saponins of Korean ginseng, Panax ginseng C.A. Meyer, were performed according to the cultivating locations, sampling seasons, plant parts, and growing stages. The changes in saponin content in the course of manufacturing Red ginseng and Ginseng extract were observed. In this paper, a new method for the determination of the total and the individual saponin glucosides was proposed and applied to the samples under study. The method employing Digital Densitorol DMU-33C (Toyo electric Co., Japan) followed the separation of the saponins by means of a preparative thin layer chromatography. The saponin contents and their fractional distribution were summarized as follows: 1. The average concentrations(% plant dry weight) of semi-purified saponins in the roots of Korean ginseng planted in the various locations were 5.0%(Keumsan), 6.0% (Kimpo), and 5.4% (Pocheon), respectively. 2. There were 3.3% saponins in White ginseng(Rhizome) and 12.7% saponins in Ginseng tail (Fibrous root). 3. Regarding the year of growth, the contents of saponins were 90.3mg (2-year-old ginseng), 254.4mg (3-year-old ginseng), 404.2mg (4-year-old ginseng). 999.6mg (5-year-old ginseng), and 1377.1mg (6-year-old ginseng) respectively, and the saponin factions containing panaxatriol as an aglycone increased. 4. Thin layer chromatography revealed that Red ginseng yielded many saponins which Shibata et al. designated as $ginsenoside-Rb_1$ (22.1%), $-Rb_2(15.4%)$, -Rc(12.6%), -Re (15.7%), and $-Rg_1$, (9.3%). 5. 29.9% of crude saponins were isolated from ethanolic extract of Panax ginseng fibrous root and their extraction yield was 94.2% of fibrous root saponin.

The patterns of ginseng saponins in the commercial ginseng tea samples and each parts of ginseng plant were investigated by quantitative thin-layer chromatography. The quality of those sample teas were also evaluated. (1) White ginseng contained about $2.6{\sim}6.6$ times of Ra(o) than did other parts of ginseng. (2) Lateral roots, peelings and buds of ginseng were rich in $Rb_1$, $b_2$, c, which constituted about 50% of total saponin. (3) The ratio of Rb.c to Rg(f) in the leaves and stems of ginseng plant was 0.64 : 1. (White ginseng, 2 : 1 ; buds, 3 : 1 ; flower, 3.2 : 1 ; peelings, 5.8 : 1 ; lateral ginseng, 7 : 1) The relative content of Rg(f) in the white ginseng was about 3 times as much as the lateral ginseng. (4) The ratios of panaxadiol to panaxatriol in 13 kinds of commercial ginseng teas were in the range of $0.8{\sim}8\;:\;1$.

The purpose of this study was to explore the characteristics of and solution to thermogenic reactions to Korean ginseng through bibliographic research. A review of bibliography on the thermogenic reaction induced by ginseng indicated that people who lack fluids, have fever in lungs, a stuffy chest, coughing up sputum, a strong pulse, and constipation due to fever in the stomach may exhibit such a reaction. In the herbal medicine book of the Qing Dynasty, Bon-Cho-Jeong-Ui (本草正義) recorded that wild simulated ginseng is slightly cold and replenishes the body's liquid reserves. The book also describes the field cultivated ginseng is slightly warm and enhancing stamina. Bon-Kyung-Bong-Won (本經逢源), Bon-Cho-Pyon-Dok (本草便讀), and Bon-Cho-Jeong-Ui were published authors in the Qing Dynasty, and they explained that ginseng fine root is bitter, supplements bodily fluids, and can be easily ingested because it is cold. Wol-Ji-In-Sam-Jeon (月池人蔘傳) and Bon-Cho-Bi-Yo (本草備要) described fresh ginseng assweet, bitter, and slightly cold in the Ming and Qing Dynasties, respectively. On the basis of this bibliographic description, the thermogenic reaction induced by Korean ginseng can be overcome by using ginseng fine root, fresh ginseng, or wild simulated ginseng. These ginseng radices are slightly cool, replenish human bodily fluids, and show the physiological effects of easy ingestion properties.

In order to determine the stability of ginseng components in this salt concentration when used to ginseng as additive ingredient of sauces or seasonings, we study on the content and charactristic of ginsenosides and changes in pH and color, ginseng tail and ginseng extract were treated with various concentration of NaCl solution. In this experiment, extract of ginseng tail were increased in pH as NaCl concentration were increased, but ginseng extract have not changed evidently. The both solution were decreased in color as the salt concentration were increased. Yield of n-butanol extract was decreased in 5% NaCl concentration, while it was increased in the above concentration, and ginseng extract was changed higher than ginseng tail. Ginsenosides content were increased in 5% NaCl concentration, both $ginsenosied-Rb_1$, $-Rb_2$, -Rc, -Rd of diol line and ginsenoside-Re of triol line and increased in above NaCl concentration. Especially ginsenoside-Re showed to sensitive response to the changes of the salt concentration.
