In this study, quality in terms of the surface color and constituents of white ginseng prepared with different peeling time by using barker were investigated. The color of the white ginseng become better according to the increasing of peeling time. The components, such as contents of crude fat, crude protein, fatty acids, amino acids were slightly increased by the peeling, but carbohydrate and sugars were decreased. The contents of crude saponin and ginsenosides were markedly influenced. Compared with intact ginseng roots, peeling of ginseng roots resulted in a substantial decrease (approximately 20-30%) in total ginsenoside contents. The results suggest that peeling for white ginseng preparation leads to improve the surfacecolor formation of roots, while lose the contents of ginsenosides as the major active ingredients of ginseng.

The extract of Platycodi radix has long been used as an anti-inflammatory traditional medicine in Korea for the treatment of bronchitis, asthma and acute respiratory disease. In this study, the anti-inflammatory actions of the methanol extract of Platycodi radix administered via oral administration were evaluated. The results revealed that the extracts exhibited potent anti-inflammatory action. Of the hexane, chloroform, ethyl acetate, butanol and water fractions, the butanol fraction had the most potent anti-inflammatory action. Additioinally the sapogenin obtained through acid hydrolysis of the butanol fraction did not show anti-inflammatory action. These findings confirm the value of Platycodi radix as a traditional Korean medicine.

The pharmacognostical and pharmacological studies of 'Manryong' were carried out, which has been widely used in Chun-Ra Province, Korea and the following results were obtained. 1) The original plant of the bulb MANRYONG is Erythronium japonicum DECNE. (Liliaceae). 2) The internal structure consists of mostly parenchyma containing numerous starch grains, vascular bundles and substituted fibers. 3) The external surface occurs as a yellowish white and slightly bented ovoidal shape. 4) 'Manryong; contains 11 kinds of free amino acids, such as asparagin, tryptophan, cystine, glutamic acid, threonine, glycine, leucine, proline, histidine, methionine, and alanine. 5) Hemolytic action of the crude saponin isolated from 'Manryong' is weaker than that of digitonin. 6) Effects of 'Manryong' extracts on ceruloplasmin were studied and an antidotal activity of the extracts was found in liver intoxicated with carbon tetrachloride.

In order to obtain the basic data for the preparation of yogurt containing ginseng component, the effect of ginseng component on cell growth of Lactobacillus casei YIT 9018 and on lactic acid production were investigated. Initial cell growth and acid production were markedly inhibited by the addition of ethanol extracts in the level of 8% into 15% skim milk. Crude saponin did not show any inhibitory effect on cell growth and acid production, but ether layer fraction showed inhibitory effect. It was thought to be more advantageous to add ginseng extracts after the fermentation of milk than before. The addition of ginseng extract at 8% level into liquid yogurt was most suitable in organoleptic test. Cell viability was not affected by the addition of ethanol extracts up to 8% level during storage of liquid yogurt.

Strong anti-inflammatory saponins Phytolacca americana (Phytolaccaceae) wereobtained from callus mass derived from the stems and also from that derived from the roots of cultivated Phytolacca americana (which were designated as PAS and PAR, respectively). The callus were grown on Linsmair and Skoog's agar medium supplemented with 1ppm OF 2, 4-dichlorophenoxyacetic acid. Phytol accoside B and D were obtained from PAS and phytolaccoside A and B from PAR. The thin layer chromatograms of the crude saponins from PAS and PAR were similar to those of original plants. PAS contained phytolaccoside B as a major component while phytolaccoside E was a major saponin in original plants.

Red ginseng tails were extracted with ethanol solutions over a range of concentrations and temperature conditions. Investigations were carried out to study the effects of treatments on yields, soluble solids, saponin and precipitate occured in red ginseng extract beverage during storage. It was found that: (1) Higher concentration of ethanol at low temperature resulted in less yield of crude extract (2) The amount of precipitate in the non-purified extract beverage were less with decrease in ethanol concentration used (3) The treatment for purification of extracts and storage of purified extract at 37$^{\circ}C$ for 6 months had no effect on HPLC chromatogram pattern of saponins (4) The amount of purified extract decreased by purification treatment and more decrease was found as the temperature and concentration of ethanol increased. For Preparation of red ginseng extract beverage, the treatment of extracts with ethanol at low temperature was found to be more effective to minimize precipitation in tile beverage.

The effect of puffing treatments on the sensory qualities improving of Ginseng Extract were investigated in the good products for rejecting soil flavor as Ginseng foreign bad taste, through chemical analysis and actual manufacturing practice, the following results were obtained. Puffing treated<15kg / ㎠psi> ginseng has produced a marked increase in soluble solid, crude saponin yield to the extent of 10% and without soil taste as compared with control Ginseng. Optimum Ginseng ethanol extraction condition were 90$\^{C}$ for 8 hours, which was cheap operating cost and color, apperance, total solid yield of Ginseng extracted products. For 70% ethanol extraction in temperature range of 60∼90$\^{C}$ for 8 hours, the higher temperature resulted higher yields in solids and Ginsenoside Especially, GinsenosideRgl as most effective physiological function component yield was increased in 18% by puffed Ginseng than control Cinseng products. The Hunter's color, L. a and b values of Ginseng extract were 31.09, 21.9 and 49.5 and increase brown and red color value and total Δ Evalue.

Hydrolysis properties of ginseng saponins in processing of extraction with vacuum impulse system extraction method were compared with multi-stage extraction methods. Crude saponin content of the extract produced by vacuum impulse system extraction method was $11.5\%,$ compared with multi-stage extraction method (about $8.13\%).$ Also the yield of the extract increased about $6.7\%.$ The flavor and aroma of ginseng extract with vacuum impulse system extraction method are stronger than multi-stage extraction methods and people have a tendency to like more. The color was similar to existing extraction items and the liquidity ratio was high. Vacuum impulse system extraction method could save human resources because of short extraction time and automatic operation of processing. With HPLC pattern, We could ascertain the truth that hydrolysis properties of ginseng saponin was restrained in the extraction processing, vacuum impulse system extraction method.

This study compared the contents of ginseng prosapogenin depending on the extracting conditions of Ginseng Radix palva(Panax ginseng) to provide basic information for developing Ginseng Radix palva-based functional foods. Our findings show that the content of crude saponin peaked at 18 hours of extraction and when extracted twice at $100^{\circ}C$ (GRP-18). However, the content of total saponin reached its height at 6 hours of extraction at $100^{\circ}C$ (GRP-6) and when extracted twice. On the other hand, the content of ginsenoside $Rg_3$, $Rg_5$ and $Rk_1$ from Red and Black ginseng reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction at $100^{\circ}C$. And at $100^{\circ}C$ the main prosapogenin of the content of Black ginseng ginsenoside $Rg_5$ and $Rk_1$ reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction.
