Definitions

  • the present invention relates to a composition based on eremophilanolides and their use, in particular for the production of a dietary supplement or dietetic foodstuff and a pharmaceutically active composition for the treatment of disease states.
  • Petasites hybridus or the common butterbur is a medicinal plant known since ancient times. Depending on the type of ingredients, a distinction is made according to recent studies, two chemotypes, namely the petasin type and the furanopetasin type.
  • the furanopetasin type also called furanopetasin variety, contains so-called furanoeremophilans, which are not found in the petasin-type plant.
  • Petasitic extract and nutritional supplements are, in particular, viscous extracts of the petasin type which have an unpleasant, bitter taste.
  • the furanopetasin type has hitherto not been used for dietary supplements or pharmaceutical preparations as an essential ingredient, since it has hitherto been assumed that only the petasin-type petasins have a pharmacologically active action.
  • the furanopetasin type in contrast to the petasin type (Petasin chemovariancy), the furanopetasin type (Furano chemovariancyte) has cytotoxic properties.
  • Branching of the alkyl side chain with at least one of the nucleic acids is branching of the alkyl side chain with at least one of the nucleic acids.
  • the highest toxicity and carcinogenicity are probably due to the cyclic diesters.
  • the Pyrrolizidinalkaloide are rapidly absorbed after peroral absorption, their N-oxides only after reduction by the intestinal flora.
  • the pyrrolizidine alkaloids are converted by mixed-function oxidases into very toxic pyrrole derivatives. These are highly reactive and alkylate under physiological conditions nucleophilic groups of the DNA, such as amino, thiol and hydroxy groups.
  • petasin-type petasites have been shown to have cytotoxic and hepatotoxic potential despite complete removal of pyrrolizide maltoids.
  • the object of the present invention was to provide a composition, the composition comprising a plant extract, obtainable from plant parts of the butterbur, which is free of pyrrolizide maltoids and has no cytotoxic and hepatotoxic potential.
