The present study was undertaken to determine the inhibitory effects of orally administered ginseng saponins (GS), protopanaxadiol saponins (PD), protopanaxatriol saponins (PT) and ginseng ether fraction (GE) on the development of morphine induced tolerance and physical dependence in mice and also to determine the hepatic glutathione contents. GS, PD and PT inhibited significantly the development of morphine induced tolerance and physical dependence, but GE was effective only on the inhibition of the development of morphine induced physical dependence. GS, PD, PT and GE also inhibited the hepatic glutathione level decrease induced by morphine multiple injections.

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).

The patterns of saponins of lateral gingengs cultivated different areas and various ginseng products were investigated by quantitative thin-layer chromatography. In the case of ginseng cultivated in the Kum San and Gang Hwa area, some parts of the panaxatriol series of the saponins (peak 6 and 7.8.9) were higher in concentration than in ginseng grown in other areas while the other ingredients were almost the same. In the process of heat treatment the quantity of peak 2 was generally decreased. However, in the case of red and white ginseng, one part of the panaxatriol saponins, peak 6 was increased. This tendency was also found in honeyed ginseng and ginseng tea which were not exposed to sunlight, but the increase was much less. The change in the red and white ginseng which were exposed to sunlight was very substantial. Therefore we can assume that the increase of peak 6 comes about due to the combination of heat treatment and exposure to sunlight, especially due to exposure to sunlight.

Saponins in leaf and stem of Gynostemma pentaphyllum that was collected from Jeju Island were extracted by the method for ginseng saponin. Comparison by overlapping chromatogram(HPLC) of pentaphyllum on that of ginseng and cochromatogram and ginseng although ginsenoside Rg2, Rg1 and Rf might be in common with rare possibility. It seems to be little difference in the kind of saponin glycosides between leaf and stem of pentaphyllum. Saponin content in leaf of pentaphyllum was higher than in stem, and much higher than those in ginseng. The kind of saponin glycoside in pentaphyllum appeared to be less than 22 and greater than those in ginseng. There was almost no change in saponins of pentaphyllum in methanol for 3 years at room temperature.

The ginseng plant (Panax ginseng Meyer) has a large number of active ingredients including steroidal saponins with a dammarane skeleton as well as protopanaxadiol and protopanaxatriol, commonly known as ginsenosides, which have antioxidant, anticancer, antidiabetic, anti-adipocyte, and sexual enhancing effects. Though several discoveries have demonstrated that ginseng saponins (ginsenosides) as the most important therapeutic agent for the treatment of osteoporosis, yet the molecular mechanism of its active metabolites is unknown. In this review, we summarize the evidence supporting the therapeutic properties of ginsenosides both in vivo and in vitro, with an emphasis on the different molecular agents comprising receptor activator of nuclear factor kappa-B ligand, receptor activator of nuclear factor kappa-B, and matrix metallopeptidase-9, as well as the bone morphogenetic protein-2 and Smad signaling pathways.

A rapid separation of an edible panaxadiol (PD) and panaxatriol (PT) in ginseng saponins has been investigated by benzene ethylene resin adsorption method. Briefly, powdered red ginseng was extracted with water. The obtained ginseng extract were dissolved in suitable volume of distilled water, and adsorbed on the benzene ethylene resin with 200 folds water of the resin weight. Sugars and hydrophilic character compounds not absorbed were washed with water, and eliminated by 10-fold water of the resin weight. An edible panaxadiol and panaxatriol can be perfectly separated from ginseng saponins with the fractions below 40% aqueous ethanol and over 45% as an fluent.

The analgesic effect of morphine was antagonized and the development of tolerance was suppressed by the modification of the neurologic function in the animals treated with ginseng saponins The activation of the spinal descending inhibitory systems as well as the supraspinal structures by the administration of morphine was inhibited in the animals treated with ginseng saponine intracerebrally or intrathecally. The development of morphine tolerance and dependence, and the abrupt expression of naloxone inducted abstinence syndrom were also inhibited by ginsenoside Rb1, Rb2, Rg1 and Re. These results suggest that ginsenoside Rbl, Hbs, Rgl and Re are the bioactive components of panax ginseng on the inhibition of the development of morphine tolerance and dependence, and the inhibition of abrupt abstinence sindrome. In addition, further research on the minor components of Pnnnxkinsenl should be investigated. A single or daily treatment with ginseng saponins did not induce any appreciable changes in the brain in level of monoamines at the variolls time intervals and at the various day intervals, respectively. The inhibitory or facilitated effects of ginseng saponins on electrically evoked contractions in guinea pig ileum ($\mu$-receptor) and mouse vats deferens ($\delta$-receptor) were not mediated through opioid receptors. The antagonism of a $\chi$ receptor agonist, U-50, 488H was also not mediated through opioid receptors in the animals treated with ginseng saponins, but mediated through serotonergic mechanisms. Ginseng saponins inhibited morphine 6-dehydrogenase which catalyzed the production of morphinone from morphine, and increased hepatic glutathione contents for the detoxication of morphinone. This result suggests that the dual action of the above plays an important role in the inhibition of the development of morphine tolerance and dependence.

Background: Among the various ginseng strains, Shizhu ginseng is endemic to China, mainly distributed in Kuandian Manchu Autonomous County (Liaoning Province, China); however, not much is known about the compounds (especially saponins) in Shizhu ginseng. Methods: A rapid, sensitive, and reliable ultra-high performance liquid chromatography coupled with MS/MS (UHPLC-MS/MS) method was developed to separate and identify saponins in Shizhu ginseng. Results: The separation was carried out on a Waters ACQUITY UPLC BEH $C_{18}$ column ($100mm{\times}2.1mm$, $1.7{\mu}m$) with acetonitrile and 0.1% formic acid aqueous solution as the mobile phase under a gradient elution at $40^{\circ}C$. The detection was performed on a Micromass Quattro Micro API mass spectrometer equipped with electrospray ionization source in both positive and negative modes. Under the optimized conditions, a total of 31 saponins were identified or tentatively characterized by comparing retention time and MS data with related literatures and reference substances. Conclusion: The developed UHPLC-MS/MS method was suitable for identifying and characterizing the chemical constituents in Shizhu ginseng, which provided a helpful chemical basis for further research on Shizhu ginseng.

Red ginseng possibly has new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steamings and dryings process was used for the production of red ginseng from 6-year old ginseng roots. Saponin was extracted from each red ginseng produced at the 1st, 3rd, 5th, 7th, and 9th during the steaming and drying treatment, and we analyzed saponin content with TLC. Minor saponins, such as ginsenoside-Rg3, -Rh2, compound K, and F2, increased as the process time of steaming and drying, but major saponins (ginsenoside-Rb1, -Rb2, -Rc, -Rd, -Re, -Rf, -Rg1) were decreased. Major saponins were yet observed almost at the 1st process, then degraded as the increasing time of steaming and drying process. Especially, ginsenoside-Re and -Rg were observed as considerable amount after the 1st treatment, but there were no trace of them after the 9th treatment. Ginsenoside-Rg1, -Rb2, and -Rb1 were also reduced remarkedly by 96.6%, 96%, and 92.3%, respectively. Minor saponins were increased significantly, especially for ginsenoside-Rg3 and ginsenoside-F2. These results suggest that Kujeungkupo method is the very useful method for the production of minor ginsenoside-Rg3 and -Rh2.
