Response surface methodology was used to predict the optimum conditions of explosive puffing process for ginseng. A central composite design was used to monitor the effect of moisture content and puffing pressure on dependent variables such as functional compounds (extract yield, crude saponin, acidic polysaccharide, and total phenolic content) and sensory properties. Correlation coefficients $(R^2)$ of models for crude saponin, acidic polysaccharide, and total phenolic content were 0.9176 (p<0.05), 0.9494 (p<0.05), and 0.9878 (p<0.001), respectively. Functional compounds increased with decreasing moisture content and increasing puffing pressure. Overall palatability was high at 15-20% moisture content and 98-294 kPa of puffing pressure. On the basis of superimposed contour maps for functional compounds and overall palatability of puffed ginseng, the optimum ranges of puffing conditions were 10-17% moisture content and 294-392 kPa puffing pressure.

This study was performed to measure the antioxidant effects of red ginseng extracts which antioxidation had been promoted through enzyme hydrolysis. In order to observe their tumor-suppressing effects, an anti-cancer medicine and Saponin-SOD, which was a highly antioxidant beverage made from red ginseng saponin adding SOD-like rice (with embryo buds) extracts, were administered to nude mice with large intestine cancer induced. There was a significant increase in the content of phenolic compounds as the enzyme was added. The red ginseng extracts showed a high electron-donating ability with the passage of time. The electron-donating ability was particularly high in the enzyme-treated red ginseng extract, and also observed as high in Saponin-SOD. The lipid-peroxide generation was inhibited depending on the concentration of Saponin-SOD added; the addition of 0.625% Saponin-SOD served to decrease the inhibition level up to 65% compared with the case of no addition (100%). As a result, it could be assumed that Saponin-SOD would strongly inhibit the oxidation of ghost membrane. After the cancer was induced in nude mice through the injection of SNUC-4 cell, there was a significant inhibition in the growth of tumors in nude mice into which Saponin-SOD were injected; the growth of tumors was gradually decreasing with the passage of time after the cancer induction. In particular, when Saponin-SOD was administered together with an anti-cancer medicine, the synergic effect was observed. In conclusion, Saponin-SOD, when used with an anti-cancer medicine, is expected to reduce the amount of free radical and lipid peroxide, which are known to cause harmful effects occurring from the internal application of medicine.

Korean ginseng has been thought and used the most very important medicinal herb among the oriental medicinal drugs for thounds of years Korean ginseng had many ingredients such as tripenoid saponins. Nitrogen compounds, polysaccharides, polyacetylenic compounds and lipid compounds. Korean ginseng has wide effects in the various systems of human such as nervous system. Vascular system. Digestive system. endocrine system, immune system. etc. Many researchess who were interested in the biological effects of Korean ginseng have concerned the tripenoid saponins among the components of ginseng and carried out to find the effects of ginseng using the various experimental system. From their results, it was unveiled many effects of Korean ginseng gractually in the experimental systems and shown that Korean ginseng has various effects in the biological system. But recent studies has been carried out to the difference ginseng components, besides ginseng saponin thought to have various effects in biological systems. Also the functional mechanism of ginseng in the biological system is limited but the basic research to elucidate the mysterious effects of ginseng has been preferred. In this review, we focus on biological effects of Korean ginseng. Especially physiological and biochemical aspects in biological systems.

Ginseng root explants and calli induced from selected cell lines were cultured on modified Murashige and Skoog's media supplemented with different concentrations of organic or inorganic compounds and plant growth requlators to clarify the effects of chemical composition and plant growth regulators in the medium on the growth of ginseng calli and the production of ginseng saponin. For optimum growth of calli, the concentrations of 2, 4-D and sucrose were the range of 1 to 3 mg/${\ell}$l and 1 to $3\%,$ respectively. And it was clarified that sucrose, nitrogen, phosphate, calcium, magmesian plant growth regulators and their concentrations influcenced the relative biosynthesis of saponin in tissue cultures of Panax ginseng. The patterns of ginsenosides, pharmacologically useful component, were different among the cell lines and contents of ginsenosides were much higher in selected cell lines than in original cell line.

The investigation of UV absorbing compounds in saponin fraction of Pnm.1. Kiairnk root was carried out by thin layer chromatography, semipreparative HVLC. l3C, 1H-NMR, mass spectrometry and chemical characteristics in searching plant for growth regulatony substances such as phenolic glycoside. Drying of fresh ginseng at 15 $^{\circ}C$ decreased not only number but also size of UV absorbing sports on TLC. One of the relatively large spots in fresh ginseng was isolated and identified as adenosine, which is subjected for growth stimulatory activity Detection of phenolic glycosides failed in dried root bolt was highly probable in fresh ginseng even with the insufficient amount of sample.

Free malonaldehyde was determined in nine kinds of ginseng polyacetylene-treated micro- some by HPLC analysis. Antioxidant activities of some phenolic compounds and ginseng saponin were also drtermined both by a new HVLC method and by THA method. A new HPLC system separaterl malonaldehyde at a retention time 5,6 min and showed a linear relationship between the peak are a and malonaldehyde concentration. Panaxnol showed the strongest activity among nine polyacetylenes and the addition of either chlorine or aletyl group reduced polyacetylene's own activity. Since C14-polyacetylenes such as panaxyne and panaxyne-epoxide had little or no antioxidant activities, S17-structure should be preserved to exert a radical-scvenging or trapping activity. The antioxidant activities of chlorogenic acid, ferulic acid and catechol were much weaker than those of C17-polyacetylenes. Ginseng saponin showed no antioxidant activity. Since TBA reactive substances and malonaldehyde contents were almost the same in peroxiedized microsome. TBA value seems a good indicator for lipid peroxidation in this particular Fe+3 ADP/NADPH system.

We have been isolating various physiologically active substances from non-saponin fraction of Korean Red Ginseng These are adenosine, gyro-glutamic acid, dencichine and acidic polysaccharide. Adenosine and gyro-glutamic acid are loom to inhibit epinephrine-induced lipolysis in fat cells and stimulate the insulin-mediated lipogenesis. In addition to these actions, adenosine was found to inhibit both norepinephrine- and histamine-induced aorta constriction, and pyre·glutamic acid inhibits angiotensin-converting enzyme. Dencichine stimulated histamine-induced aorta constriction. Finally, acidic polysaccharide was found to inhibit both lipolytic and anorexigenic actions of Toxohormone-L. Based on these experimental results, I presented a brief review on these compounds isolated from non- saponin fraction of Korea Red Ginseng. Keywords Panax ginseng, Korean red ginseng, adenosine, pyroglutamic acid, dencichine, acidic polysac- charide, lipolysis, lipogenesis, angiotensin-converting enzyme, toxohormone-L.

Background: Panax ginseng Meyer (Araliaceae) is a highly valued medicinal plant in Asian regions, especially in Korea, China, and Japan. Chemical and biological studies on P. ginseng have focused primarily on its roots, whereas the seeds remain poorly understood. This study explores the phytochemical and biological properties of compounds from P. ginseng seeds. Methods: P. ginseng seeds were extracted with methanol, and 16 compounds were isolated using various chromatographic methods. The chemical structures of the isolates were determined by spectroscopic data. Antiinflammatory activities were evaluated for triterpene and steroidal saponins using lipopolysaccharide-stimulated RAW264.7 macrophages and THP-1 monocyte leukemia cells. Results: Phytochemical investigation of P. ginseng seeds led to the isolation of a novel triterpene saponin, pseudoginsenoside RT₈, along with 15 known compounds. Pseudoginsenoside RT₈ exhibited more potent antiinflammatory activity than the other saponins, attenuating lipopolysaccharide-mediated induction of proinflammatory genes such as interleukin-1β, interleukin-6, inducible nitric oxide synthase, cyclooxygenase-2, and matrix metalloproteinase-9, and suppressed reactive oxygen species and nitric oxide generation in a dose-dependent manner. Conclusion: These findings indicate that pseudoginsenoside RT₈ has a pharmaceutical potential as an antiinflammatory agent and that P. ginseng seeds are a good natural source for discovering novel bioactive molecules.
