Determination of ginsenoside Rf and Rg2 from Panax ginseng using enzyme immunoassay.
Chem. Pharm. Bull. 46(7) , 1144-7, (1998) We have developed an enzyme immunoassay (EIA) to quantify trace amounts of ginsenoside Rf (Rf), one of the glycosides of protopanaxatriol from Panax ginseng. A carrier protein of bovine serum albumin (BSA) was coupled to the carbohydrate component of Rf using... |

Microbial conversion of rare ginsenoside Rf to 20(S)-protopanaxatriol by Aspergillus niger.
Biosci. Biotechnol. Biochem. 74(1) , 96-100, (2010) In this study, rare ginsenoside Rf was transformed into 20(S)-protopanaxatriol (PPT(S)) by glycosidase from Aspergillus niger. By investing the reaction conditions, the optimal conditions were obtained, as follows: pH 5.0, temperature 55 degrees C, and substr... |

Biotransformation of ginsenoside Rf to Rh1 by recombinant beta-glucosidase.
Molecules 14(6) , 2043-8, (2009) An Aspergillus niger strain was isolated from the soil around ginseng fruit. In vitro enzyme assays showed that this strain had the ability to transform total ginsenosides (TGS) into several new products. In a further biochemical study, a beta-glucosidase gen... |

Modulating effect of ginseng saponins on heterologously expressed HERG currents in Xenopus oocytes.
Acta Pharmacol. Sin. 26(5) , 551-8, (2005) To examine the effects of ginseng saponins on the heterologously expressed human ether-a-go-go related gene (HERG) that encodes the rapid component of the delayed rectifier K+ channel.A two-electrode voltage clamp technique was used. HERG currents were record... |

Ginsenoside Rf, a component of ginseng, regulates lipoprotein metabolism through peroxisome proliferator-activated receptor alpha.
Biochem. Biophys. Res. Commun. 339(1) , 196-203, (2006) We investigated whether ginseng regulates lipoprotein metabolism by altering peroxisome proliferator-activated receptor alpha (PPARalpha)-mediated pathways, using a PPARalpha-null mouse model. Administration of ginseng extract, ginsenosides, and ginsenoside R... |
