To develop a new functional food material, edible crude saponin was isolated from soybean cake using HP-20 resin and its anticancer effect and immune-activity were investigated. The saponin significantly inhibited the growth of cancer cells such as A549, MCF-7 and SW480 at a concentration of 1,000 $\mu$g/mL. Morphological changes was observed in the AS49 cells surface treated with the saponin of 1,000 $\mu$g/mL concentration. The proliferation of mouse spleen cells treated with saponin was increased in a dose-dependent manner compared with untreated control cells until the concentration of 1 $\mu$g/mL but decreased at higher concentrations than that. The NO production in marcrophage cell lines (RAW 264.7) treated with saponin was increased in a dosedependent manner compared with untreated control cells.

Using an ethopharmacological technique, we demonstrated that saponin fraction from red ginseng root possessed a potent psychotropic actions on either intermale or maternal aggression models. A series of experiments clearly indicated that one of psychoactive ingredient is ginsenoside Rbl. Although a drug-induced debilitation of motor performance remains a possible cause of the antiaggressive affect of the drug. ginsenoside Rbl did not alter the locomotor activity of the mice during agonistic confrontations. Thus. one can eliminate the possibility that the psychotropic effect of ginsenoside Rbl might be concealed by a drug-induced impairment of motor performance. More recently, we developed a nevi model for copulatory disorder and introduced into the behavioral analysis of drug action. Male mice which has been housed individually from weaning for 5 weeks failed to manifest copulatory behavior when they encountered with the sexually receptive females. Daily administration of crude ginseng saponin during isolation housing period prevented the development of copulatory disorder, whereas both ginsenoside Rbl and Rgl were ineffective. A further experiment may be needed to explore active ingredient of ginseng saponins.

This study was carried out to compare the root yields, root characters, saponin and ginsenosides contents of 6-year-old p. ginseng and p. quinquefolium. These two ginseng species showed difference in the diameter and ten비h of mainroot. The main root length or p. quinquefolium was shorter than that of p. ginseng, whereas Jakyung-jong and Hwangsook-jong of P. ginseng showed similar root length. Proximate composition were similar between the two species, however, crude fibercontent was significantly higher in main and lateral root of Jakyung-jong and Hwang sook-jong of P ginseng than P quinquefolium. In regard to mineral contents of root, P ginseng contained more Ca and Mn and less Fe and Al than P. quinquefolium. P. quinquefolium contained more of Rbl and Rd of protopanaxadiol saponin, and less or Re, $Rg_1$ and $Rg_2$ of protopanaxatriol saponin than P ginseng. However, no Rf was detected in the p. quinquefolium. Key words Panax ginseng, Panax quinquefolium, ginseng character, ginsenoside.

To find out the possible variation in chemical composition among ginseng products, the amount of saponin, extract and other basic components in different age and portion of ginseng roots(Panax ginseng Meyer) were investigated and compared with. (1) Great difference in the amount of ash, crude protein, fiber, fat, total sugar and reducing sugar was observed among different portion of the root comparing with those of different age of the root. That of ash, crude fiber, saponin and extract produced was higher in epidermis, fiber roots and subterranean stems, while that of crude protein, total sugar, panaxadiol/panaxatriol was higher in central portion and branch of the root. (2) The amount of extract produced was affected by the solvent used. Higher amount was obtained when water was employed. It was decreased as the increase of the concentration of alcohol solvent. Futhermore, the composition and physical properties were greatly varied by the concentration of alcohol solvent. (3) The amount of total-N, $P_2O_5,\;K_2O$, and ash was higher in two to three years old roots, while those of crude $SiO_2,\;CaO,$ crude fiber, and total sugar was higher in order roots. No difference was found in amount of MgO, Fe, Zn, and Na among age of the root.

The physicochemical properties of raw and black doraji were examined with the goal of increasing the utilization of doraji. Raw and Black doraji contained similar amounts of crude ash, crude fat, and crude protein, but raw doraji had higher level of fiber. Arginine was the major free amino acid in both types of doraji. Free sugar and organic acid contents of doraji increased after steaming heat treatment. Potassium was a prominent mineral in both raw and black doraji, constituting 85% of total minerals. Black doraji contained almost twice as much crude saponin as did raw doraji. Black doraji showed lower values of L (lightness), a (redness), and b (yellowness). The hardness and chewiness of raw doraji were higher than those of black doraji. Black dorai showed a higher amount and extraction rate of saponin, even though nutrient value of doraji slightly decreased after steaming heat treatment. Therefore, black doraji can be a valuable ingredient in functional foods.

Proximate analysis and antioxidant activity of cultivated wild Panax ginseng (CWPG) were investigated to provide fundamental information of CWPG with different ages and to increase its industrial application. Proximate analyses of CWPG with different ages were performed. Extraction of CWPG with different ages was carried out using heat-reflux extraction, and their extraction yield, crude saponin content, ginsenoside content, and antioxidant activity were analyzed. Moisture content decreased, but crude fat and crude protein were increased with aging. Extraction yield and crude saponin contents did not show a specific pattern while 5-year-old CWPG revealed the highest extraction yield and crude saponin content. All CWPGs showed typical ginsenoside profiles containing C-K and Rh2 ginsenosides, which are not found in ginseng. The 3-year-old CWPG showed the highest antioxidant activity including total phenolic content, total flavonoid content, and DPPH and ABTS radical scavenging activities. Moreover, 3-year-old CWPG also revealed the highest acidic polysaccharide content. Therefore, these results suggested that 3-year-old CWPG, which is the cheapest, can be used in industrial application due to its high antioxidant activity and acidic polysaccharide content with similar ginsenoside profile compared to 5- and 7-year-old CWPGs.

A series of experiments clearly indicated that one of psychoactive ingredient is ginsenoside Rbl. Although a drug-induced debilitation of motor performance remains a possible cause of the antiaggressive effect of the drug, ginsenoside Rb 1 did not alter the locomotor activity of the mice during agonistic confrontations. Thus, one can eliminate the possibility that the psychoactive effect of ginsenoside Rbl might be concealed by a drugindulced impairment of motor performance. More recently, we developed a new model for copulatory disorder and introduced into the behavioral analysis of drug action. Male mice which has been housed individually from weaning for 5 weeks failed to manifest copulatory behavior when they encountered with the sexually-receptive females. Daily administration of crude ginseng saponin during isolation housing period prevented the development of copulatory disorder, whereas both ginsenoside Rbl and Rgl were ineffective.

Polygalae Radix was used as diuretics, analgesics and expertorants in oriental medicine. The root of Polygala tenuifolia Willd. (Polygalaceae) is comprised saponin (Onjisaponin A,B,C,D,E,F and G) polygalitol, onsitin and sugars. The pharmacological action of crude Polygala-saponin (PS) obtained from the roots are studied. The following results were obtained; 1) The median lethal dose $(LD_{50})$ of PS in mice is presented 71.1mg/kg s.c. and 694. 5mg/kg p.o.. 2) PS demonstrated diuretic action of relatively long acting duration in mice. 3) The diuretic mechanism of PS was found due to inhibitory effect of renal tubular reabsorption of electrolytes and glomerular vascular dilatation. 4) The group, administered simultaneously PS and cefadroxil monobydrate was significantly increased with PS alone group on diuretic action. Synergistic effect cefadroxil monohydrate on the diuretic action of PS seems due to competitive inhibition of plasma protein binding with PS. 5) PS demonstrated analgesic action by the acetic acid stimulating method and Randall-Selitto test in mice. 6) PS presented antipyretic action against febrile treated with the typhoid vaccine. 7) PS was significantly prolonged against the hypnotic duration of pentobarbital in mice. 8) Onset time convulsion and death induced by picrotoxin and strychnine in mice were not delayed. According to the above results, the PS was identified as a pharmacological active component obtained from roots of Polygala tenuifolia Willd.

This study was carried out to establish the extraction method of red ginseng extract without saponin decomposition. Red ginseng was extracted with impulse vacuum system and multi-stage extraction method. Crude saponin content of red ginseng extract (RGE) from impulse vacuum system was 5.4-5.9%, while that of RGE from multi-stage extraction method was 8.2-8.3%. However, HPLC Patterns indicated that saponins of RGE from impulse vacuum system were hardly decomposed, while those of RGE from multi-stage extraction method were decomposed, especially in ginsenoside -Rgl and -Re saponin. Also, the yields of red ginseng by impulse vacuum system were 15 to 20 times higher than that of multi-stage extraction method.
