For the purpose of utilizing the saponins of the ground part of Panax ginseng, the studies on saponins isolated from the leaves, stems, and flowers of ginseng were Performed. The results were summarized as follows: 1. The crude saponin contents of ginseng loaves, stems, and flowers 12.8%, 1.6% and 6.9% respectively. 2. Infra-red spectrum of ginseng leaf saponin was identical with that of ginseng root.

In order to shorten the extraction time of saponin in ginseng products, election with Extrelut column and phase-separation methods were compared. The results obtained are as follows. 1. Saponin of ginseng products was extracted completely within 3 hours by election method with Extrelut column, and the rate of removing glucose by the column was increased with increasing glucose content in ginseng products. 2. Stirring method was superior to refluxing method for removing sugars from ginseng products, and removing rate was deceased in the order of lactose, sucrose and glucose. 3. Extraction rate of ginsenoside from ginseng extracts by the elution method was nearly same as that of phase-separation method; however, the former was much higher than the latter in the case of ginseng teas. Therefore, the elution by Extrelut column is to be improper for extraction of saponin in ginseng tea which contains much sugar. It was necessary to remove lipophilic compounds for extraction of saponin from ginseng extracts by elution with Extrelut column.

The increased level of glucose, ketone bodies, non-esterified fatty acids and lactate in blood, decrease of glycogen content, phosphofructokinase activities and glucokinase activity and the increased level of glucose-6-phosphatase activity in the liver of streptozotocin injected rats were significantly moderated by ginseng saponin administration. It is not likely, however, that the hypoglycomic action of ginseng saponin might be due to their direct action on enzyme activities, since the saponin effect of servers enzymes in vitro was not enough to explain such an appreciable hypoglycemic activity of the saponin in streptozotocin induced diabetic rats, for which much work have to be done.

고양이 말초혈액 탐식세포(단핵구세포(MNC) 및 다형핵백혈구(PMNC))의 탐식능 에 있어서 인삼 saponin(ginseng total saponin(G75), ginseng PT saponin(GPT) 및 ginseng PD saponin(GPD))의 면역증강 효과를 flow cytometry를 이용하여 분석하였다. 인삼 ssponins을 직접 첨가하여 배양한 MNC 및 PMNC에서는 탐식중강 효과가 나타나지 않았다. 각각의 인삼 saponin을 첨가하여 배양한 PMNC 및 MNC 배양상충액의 존재하에 PMNC 및 MNC의 탐식능을 겅토한 결과, MNC의 탐식능은 Gff 첨가 PMNC 배양상충액과 GTS 및 GPT 첨가 MNC 배양상충액의 존재하에서 약간의 탐식증강 효과를 보였다. PMNC 탐식능의 경우에는 GPD 첨가 PMNC 배양상충액에서 미약한 탐식증강 효과가 나타났으나, 각각의 인 삼 saponin 첨가 MNC 배양상충액 존재하에서는 모두 현저한 탐식중강 효과를 나타내었다. 이상의 결과로부터 고양이 말초혈액 탐식세포의 탐식증강 효과는 인삼 saponin의 직접적인 작용보다는 인삼 saponin에 의해 활성화된 단핵구세포에서 분비되는 가용성물질에 의해 단 핵구세포보다는 다형핵백혈구에서 현저하게 탐식효과가 증강되는 것으로 판단되었다.

To study the effects of ginseng saponin components on the signal transduction in the ac tivation of murine macrophages, phagocytosis and Intracellular calcium concentration of peritoneal exuded mouse macrophages were examined. The phagocytosis was increased significantly after treatment with total saponin, diol-saponin, $Rg_1$ and $Rg_2$, but triol-saponin was unable to increase phagocytosis. The phagocytosis were increased when H7, a PKC inhibitor, was pretreated and increased significantly by saponin fractions except total saponin. Pertussis toxin, which inactivates G-protein, decreased the phagocytosis. But the phagocytosis was restored to the control level by saponin fractions and the phagocytosis was increased significantly by $Rg_2$ and $Rg_2$. The triol saponin increased phagocytosis approximately by 2-fold as compared with the TMB-8 treated group. Peritoneal exuded macrophages displayed a prominent rise in cytosolic calcium following treatment with triol-saponin, $Rg_1$, $Rg_2$ and $Rg_2$. Incubation of macrophages with PT resulted in an inhibition of cytosolic calcium mobilization, but increased cytosolic calcium mobilization with saponin fraction.

Effect of crude saponin and raw ginseng juice on root rot pathogens such as Fusarium solani and Erwinia carotovora for there growth or spore germination was investigated. Macroconidial germination of F. solani was decreased as the incrasee of the crude saponin concentration. especially, percentage of the germination was remarkably reduced when the concentration was more than 500ppm. The spore production of F. solani was also reduced as the increase of the crude saponin concentration and this phenomenon was particularly profound on a solid medium. Mycelial growth was decreased when the crude saponin was added, while the effect of the concentration was not apparently significant. The higher concentration of raw ginseng juice is, the more the growth of F. solani. Growth of E. carotovora was enhanced by crude ginseng saponin and raw ginseng juice. The crude ginseng saponin stimulated the growth of E. carotovora as the increase of the concentration, while more growth of the bacteria obtained at $1\%$ raw ginseng juice added.

A new quaternary ammonium compound, hydrolyzed ginseng-saponin quaternary (HGSQ), from Korean ginseng saponin and 2,3-epoxypropyltrimethylammonium chloride has been developed as a conditioning agent in cosmetics. This structure has a hydrophobic group from the aglycone of ginseng saponin which is biologically active and considered to be the most important component of the Korean ginseng. Its properties : surface tension, critical micelle concentration (CMC), eye irritation, sorption onto hair, force reduction(%) and moisture retention effect were studied. Its cationic character allows the molecule to be more substantive than ginseng saponin. HGSQ had good physical properties and was safe. enough as a cosmetic raw material. Also half-head tests of HGSQ-containing shampoo were carried out to compare the conditioning effects in shampoos. HGSQ was an excellent conditioning agent in shampoo..

The tumoricidal activity of marine macrophage against K562 tumor cells was studied in the presence of lipopolysaccharide(LPS) and ginseng saponin. 1 The tumoricidal activity was increased more by LPS treatment with ginseng saponin (44% in 24 hours) than by LPS only (22% in 24 hours). In the case of diol saponin, the tumoricidal activity was increased as much as 35% at concentrations of 10-3 to 1034%. Triol saponin increased the tumoricidal activity more than LPS only treatment at each concentration . 2. When total, dial and triol saponin were added to K.562 tumor cell in various concentration without macrophage, it was found that the ginseng saponin hall no tumoricidal effect. This result suggests that ginseng saponin increases the tumoricidal activity of K562 tumor celts through the tumoricidal activity of the macrophage.

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 $0.8{\sim}8\;:\;1$.

When ginseng saponin fractions were treated with secretion regulatory agents, it increased cAMP level at the case of thyrotropin (but the amounts were small). Total saponin increased cAMP level at DEcAMP and isoproterenol, and decreased the level at carbachol and propranolol, but at NaF it had little effect. When diol saponin or triol saponin were treated with secretion regulatory agents, biol saponin decreased cAMP level but triol saponin increased it except for isoproterenol. Also, in propra%olol, which inhibits the increase of CAMP level, diol and triol saponin showed crossing effect, too. From the above results, ginseng saponin fractions are believed that it has the, effects of promotion or inhibition on cAMP production in the thyroid , both diol saponin and triol saponin have crossing effect on thyroid hormone secretion regulatory agents. The normalizatin action of ginseng saponin fractions is notable at the case of NaF and carbachol.
