  • The present study was conducted to assess the effect of total saponins from Korean red ginseng on the biosynthesis of inositol phospholipids in vivo and also effects on the metabolic enzymes, such as phosphatidylinositol-specific phospholipase C(Pl-PLC) and PI-kinases. The administration of 0.1% saponin solution, 0.1 ml 3 times a day intraperitoneally to 5 mice for 30 days has increased a 23% of the body weight when it compared with a control group. The amounts of 32P-phoschorus radioactivity incorporated into the phosphoinositides from the liver and brain tissues have increased a 310% and 260%, respectively, in the saponin treated mice. The activities of PI-PLC from liver and brain were stimulated in the various amounts by the conditions treated with saponins. The PI-kinases from liver and brain were also activated by saponins, but its effect was lower than that of PI-PLC. From these results, it was confirmed that red ginseng saponins have affected positively not only on the biosynthesis of phosphoinositides but also on the PI-PLC and PI-kinases related to the cellular signal transduction.

  • To follow the metabolic fate of aglycone of ginseng saponins,in vitro and in vivo experiments were performed. Incubation of 20(S)-prtopanaxatriol (1) with rat liver S9 fraction afforded unique ocotillol derivatives, 20, 24-epoxysides (3 and 4). Also 20(S)-prtopanaxadiol (2) gave the corresponding epoxides (5). Healthy volunteers were taken with Sanchi Ginseng, which contains protopanaxatriol and protopanaxadiol saponins and no ocotillol saponins. From the alkaline hydrolysate of the urine samples of these volunteers,3 was detected as well as 1, and the ratio of 3/1 increased up to 2.0 at the maximum at 50 hrs. Biochemical significance of the ocotillol derivatives is discussed, since the main bioactive saponin in Panax vietnamensis is an ocotillol-type saponin, majonoside R2 (7).

  • Certain steroids and triterpenoids isolated from diverse plant families were known to posses anti-inflammatory activity. In the course of finding new anti-inflammatory natural products, some steroidal and triterpenoid saponins were isolated and evaluated for their anti-inflammatory activity using in vivo mouse ear edema test. At the oral dose of 100 mg/kg, several steroidal saponins and triterpenoid saponins such as hederagenin glycosides showed significant inhibition of ear edema (20∼37% inhibition), though less potent than indomethacin and hydrocortisone.

  • Saponins are known to be the major constituent of Panax ginseng. More than 30 kinds of ginseng saponins are reported so far. The major saponins in white ginseng (WG) or red ginseng (RG) are ginsenosides Rb1, Rb2, Rc, Rd, Rg1, and Re. HPLC method with ELSD or UV detection was used to analyze ginsenosides. Recently, a new processed ginseng with fortified activity, named as Sun Ginseng (SG), was reported. The major ginsenosides of SG are totally different from that of WG or RG, i.e., ginsenoside Rg3, Rk1, and Rg5 are the major constituents of SG. (omitted)

  • This study was performed to investigate the effects of ginseng saponins on the cerebral energy metabolite's contents influenced by carbon monoxide(CO) intoxication. Each experimental group was divided young ($5{\sim}8$ weeks) and aged ($43{\sim}52$ weeks) rats, and they were exposed at 5,000 ppm CO (72%HbCO) for 30 min. One of the other groups was pretreated with ginseng saponins for 5 days before CO intoxication. The contents of cerebral energy metabolites in cerebral cortex, stratum and hypothalamus were measured. In cerebral cortex of both young and aged rats, the levels of ATP and creatine phosphate were significantly decreased, while those of lactate were significantly increased. There was no difference between the levels of cerebral energy metabolites of young and aged rats. Pretreatment of ginseng saponins before CO intoxication lowered decrease of the levels of cerebral energy metabolites and ATP levels were significantly recovered. On the other hands, contents of lactate in stratum and hypothalamus of young rats were significantly increased and the levels of ATP and creatine phosphate in stratum and hypothalamus were completely recovered at 2 weeks after CO intoxication. The results suggest that ginseng saponins have an ameliorating action against disturbance of the cerebral energy metabolites by CO intoxication.

  • A determinatien of the saponins in ginseng tea and extract was carried out by using the quantitative TLC autodetector equipped with a hydrogen flame ionization detector. In order to apply to the Quality central of the ginseng tea and extract. the optimum condition and recovery percentage for the quantitative determination of saponins in these products duo studied. The results obtained were as follows: The method was adequate to estimate whether the ginseng extract used for the Products and She raw ginseng extract were the same quality or net. Most of the individual peak area was increased with the concentration of the total saponin. But some of the peak areas were net increased quantitatively in the ease of the sample containing high concentration ginseng extract. To deternine the saponins in ginseng tea correctly high volume low concentration was better than the low volume high concentration. Optimum concentration of ginseng extract in sample to determine the individual saponins was in the range of 0.5∼1.5g. The recovery percentage of the total saponin was 99.5% on the average.

  • The capability of the solvents for extracting the bioactive saponins from the roots of Platycodon grandiflorum (Campanulaceae) was investigated to obtain an ideal extract which contained bioactive saponins with high quality and high quantity. The content of eight representative saponins in extracts, such as deapioplatycoside E, platycoside E, platyconic acid A and platycodin D, platycodin $D_3$, platycodin $D_2$, polygalacin $D_2$, polygalacin D were analyzed simultaneousely by the modified HPLC analytical method. The validation test of the modified qualitative and quantitative analytical method employing the ELSD equipped HPLC for eight representative saponins in the roots extract of P. grandiflorum showed a good linearity, precision and accuracy. the correlation coefficient ($r^2$) values of the calbration curves for each saponins were observed to be over 0.9990. LOD and LOQ of each saponin was calculated as $0.10{\mu}g{\sim}0.40{\mu}g$ (LOD) and $0.40{\mu}g{\sim}0.80{\mu}g$ (LOQ), respectively. Recovery rates of each saponin were also calculated as over 98%, respectively. With exception of two saponins, platyconic acid A and platycodin D, The content of eight saponins in extracts was decreased proportionally to the increment of the water ratio of solvent for extraction. Consequently, as aquous alcohol was used as a solvent for extracting the saponin components from powdered roots of P. grandiflorum, the water content in the aquous alcohol was seemed to be a critical factor for extracting efficacy. The 60-80% ratio of alcohol in the aquous alcohol were deduced to be suitable and recommendable for the preparation of roots extract of P. grandiflorum which contained saponins with high quality and high quantity.

  • To develop Salicornia herbacea as a functional food material, crude polysaccharides and saponins were isolated from 80% ethanolic extracts of Salicornia herbacea using Diaion HP-20 column chromatography, and biological activities including anti-oxidation, anti-proliferation of cancer cells, and immune activities were investigated. The hydrogen-donating properties of crude polysaccharides and saponins were above 20% at $500{\mu}g/mL$ concentration. The reducing power of fractions increased in a dose-dependent manner. Crude polysaccharides and saponins at $500{\mu}g/mL$ inhibited more than 20% and 50% of proliferation by PC-3 and HT-29 human cancer cells, respectively. The anti-oxidative and anti-cancer properties of crude saponins were higher than those of crude polysaccharides. Also, proliferation in spleen cells and (nitric oxide) NO production in RAW264.7 macrophages treated with crude polysaccharides increased in a dose-dependent manner compared with the untreated control cells. However, crude saponins at concentration greater than $500{\mu}g/mL$ resulted in decreases in immune activities. Immune activities of crude polysaccharide were greater than those of crude saponins. These results indicate that Salicornia herbacea may be used as functional food materials.
