Experiments were carried out to examine the rusty tolerance in 61 inbred lines of ginseng cultivated in field, and chemical components were analyzed to clarify the difference between healthy and rusty ginseng roots. Among them, 10 lines showed rusty tolerance (RT) while 10 lines showed rusty sensitivity (RS). The content of phenolic compound in RT was lower than that in RS in cortex, epidermis and branch & fine roots, but it was not difference between RT and RS in stele. The contents of K, Ca, Na in RT were lower than RS in cortex, and the content of Mg, Fe, Na, Mn, AI, Si in RT were lower than RS in epidermis, and the content of Fe in RT were lower than RS in branch & fine roots, but mineral contents were not difference between RT and RS in stele. The content of phenolic compound in healthy cortex was lower than that in rusty cortex in same 6-year roots, but the mineral contents were not difference between healthy and rusty cortex in same 6-year roots. In root of seedlings, the contents of phenolic compound, K and Na in RT were lower than RS. It was suggested that the contents of phenolic compound, K and Na might be marker to select rusty tolerance ginseng lines.

This study carried out to scanning and select the antimicrobial pharmaceuticals which were suppress the rottening of fresh ginseng. We are isolated 20 kinds of microorganisms from rotten ginseng. In these of the microorganisms, five bacteria, fresh ginseng root-rottening, are identified to Pseudomonas putida, Pseudomonas putida biotype A, Bacillus spp, Enterobacter cloacae, and Klebsiella pneumoniae. Particularly. Bacillus spp was rapidly rotted the ginseng root, compared with the others. The antimicrobial activity were tested with 19 kinds of water extracts, and 34 kinds of essential oils. The water extract of Terminaliae Fructus, and Schiandra chinensis are strongly inhibited the growth of bacteria causing the ginseng root-rottening. And 5 kind of essential oils are inhibited bacteria. It was regarded that the water extract of Terminaliae Fructus has weekly water insoluble and polar antimicrobial components.

Excised cotyledon segments of ginseng zygotic embryos cultured on MS basal medium without growth regulators produced somatic embryos near the basal excised portion at a high frequency. The frequency of somatic embryo formation on the segments declined along with advancing zygotic embryo maturity. In immature cotyledons, all the cells of the epidermis and subepidermis were smaller and more densely cytoplasmic than those in mature cotyledons, and from which multiple cells participated in embryogenic division to form somatic embryos with multiple cotyledons and fasciated radicles (poly-embryos). But in germinating cotyledons, only the epidermal cells were densely cytoplasmic and singularly competent to develop into somatic embryos resulting in single-embryos with closed radicles. This result means that the origin and development of somatic embryos is determined according to whether the cells participating in embryonic division are in a single state or a massive state relative to cotyledon maturity.

The effect of saponin and non-saponin of Panax Red Ginseng on the blood pressure and nitric oxide production were investigated in the conscious free moving one-kidney, one-clip Goldbaltt hypertensive (lK, 1C-GBH) rats. Mean blood pressure in the control and lK, 1C-GBH rats was decreased by the administration of ginseng saponin (100 mg/kg, i.v.). The hypotensive effect induced by ginseng saponin was reached maximum at 2-4 minutes and was slowly recovered to the initial level of blood pressure. Also ginseng saponin induced reflex tachycardia in the conscious both rats. Contrast to the response induced by ginseng saponin, hypotensive effect induced by non-saponin of panax ginseng is minimal. Plasma nitric oxide concentration was increased by the treatment of ginseng saponin (100 mg/kg, i.p for 5 days) in both rats. It has been shown by western blotting that the expression level of the protein for endothelial nitric oxide synthase (eNOS) in the aorta of rats was not increased by the treatment of ginseng saponin (100 mg/kg, i.p). However, eNOS activity in aortic homogenates of both rats were increased by the treatment of ginseng saponins. From the above results, the hypotensive effect of saponin was greater than that of non-saponin of Panax Red Ginseng. The lowering effect of blood pressure by ginseng saponin may be due to the increase of plasma nitric oxide concentration via the increase of endothelial nitric oxide synthase activity in the renovascular hypertensive and control rats.

Journal of Ginseng Research, volume 23, issue 2, 1999, Pages 88~92
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
compared with multi-stage extraction method (about
Also the yield of the extract increased about
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.

In order to evalulate the qualities of red ginseng extract and decrease precipitate fonnation in ginseng drink, red ginseng extract was hydrolized with
isomaltose was produced as isomaltooligosaccharides and glucose content was increased in the enzyme treated ginseng extract. Contents of ginsenoside
were decreased, whereas ginsenoside-Rd was increased by the enzyme treatments. The growth of 3 strains of bifidus spp. and 4 strains of lactobacillus spp., beneficial intestinal bacteria, were enhanced by adding of the enzymatically hydrolized ginseng extract. Sweetness and sourness were increased, however, bitterness and astringency were decreased in the hydrolized ginseng extract. The fonnation of precipitates in hydrolized red ginseng extract of
were significantly decreased in the storage condition of
for 1 month compared to that of control.

The effects of ginseng and cinnamon extract alone or mixture on the various cancer cell lines in vitro have been examined. Human colon cancer cell line (HT-29), human rectal cancer cell line (HRT-18) and human hepatoma cell line (HepG2) were used for the experiment. When given separately, the proliferation of all cancer cell lines was inhibited in proportion to the concentration of ginseng or cinnamon extract, respectively. Based on the cytotoxic activity, mixture of ginseng and cinnamon extract demonstrated a synergistic inhibition of cancer cell growth. The progression of cell cycle from G1 to S phase was significantly inhibited by ginseng and cinnamon mixture in the HT-29 and HRT-18 cell lines.

To investigate the effects of korean ginseng on the expression of transferrin receptor (TfR) in the liver cell membrane, we had carried out the experiments of
binding, and TfR mRNA expression in the liver after partial hepatectomy of normal and 3'-methyl-4-dimethylaminoa-zobenzene (3'-Me-DAB) treated rat with or without treatment of korean gingseng.
uptake was not changed in the liver of 3'-Me-DAB or ginseng treated rat compared to that of control rat, but increased in that of partial hepatectomy of normal or 3'-Me-DAB treated rat. And this increased
uptake was lowered slightly by the treatment of ginseng. Transferrin binding sites in the liver plasma membrane of ginseng treated rat with or without partial hepatectomy were similar, but increased in that of 3'-Me-DAB treated rat with or without partial hepatectomy compared to those of each control rat and these increased binding sites were reduced by ginseng treatment. Transferrin binding affinity (l/kd) was not changed by ginseng treatment, but tended to decrease in the liver of 3'-Me-DAB treated rat or in those after partial hepatectomy of all groups and reverse by ginseng treatment in 3'-Me-DAB treated rat. The expression of TfR mRNA was increased in the liver of 3'-Me-DAB treated rat with partial hepatectomy (peak at 24 hours), but lowered by ginseng treatment in this rat. From these results, it is suggested that korean ginseng has no effect on the increased expression of TfR with decreased affinity in the cell membrane of regenerated liver after partial hepatectomy of rat, but could inhibt that of 3'-Me-DAB treated rat through the regulation of DNA synthesis or TfR mRNA in partial.

Effects of single and repeated administration of various nootropic candidates were examined on impaired acquisition by single oral administration of 3 g/kg ethanol (EtOH) in step through test. The inhibitory effect of EtOH on acquisition was significantly reduced by single picrotoxin, but not affected by diazepam, acetyl-L-carnitine and apomorphine. Single or repeated red ginseng total saponin and deprenyl, single piracetam, repeated N-methyl-D-glucamine, but not single or repeated protopanaxadiol, protopanaxatriol and centrophenoxine significantly ameliorated the impairment of acquisition by EtOH. On the other hand, the inhibitory effect of repeated red ginseng total saponin but not that of repeated N-methyl-D-Glucamine, was significantly blocked by pretreatment of
-tyrosine, a inhibitor of catecholamine synthesis. Whereas, the inhibitory effect of repeated deprenyl on EtOH amnesia was exaggerated by
-tyrosine. These results suggest that the amelioration processes of drugs on ethanol amnesia involve complex mechanism between the central GABAergic and dopaminergic neuronal activity in memory and learning, although the effects of repeated drugs administration are not yet clear.
