Disease relevance of Harpagophytum

 

High impact information on Harpagophytum

  • PURPOSE: Harpagophytum extract and its marker substance harpagoside were shown to exert anti- inflammatory effects by interacting with the eicosanoid biosynthesis [2].
  • Furthermore, in 3 independent studies with different numbers of human male volunteers, a Harpagophytum extract was administered orally and tested in whole blood samples for Cys-LT and thromboxane B2 (TXB2) biosynthesis and for the determination of pharmacokinetic parameters of harpagoside [2].
  • In addition, pharmacokinetic parameters of Harpagophytum extracts were investigated in vivo.Methods And Subjects: Different fractions of Harpagophytum extracts were tested in vitro in human whole blood samples for effects on basal and ionophore A23187-stimulated cysteinyl-leukotriene (Cys-LT) and thromboxane synthesis [2].
  • LC-DAD-MS/SPE-NMR hyphenation. A tool for the analysis of pharmaceutically used plant extracts: identification of isobaric iridoid glycoside regioisomers from Harpagophytum procumbens [3].
  • In this presentation, an existing method for the determination of the iridoid glycoside harpagoside in Harpagophytum procumbens (Devil's Claw) was successfully transferred from a conventional particle-based C18 silica column to a monolithic silica column [4].
