Abstract: A process for the preparation of an opuntia extract formulation, comprising the steps of: a) extracting plant parts selected from fruit, fruit parts, and mixtures thereof using an extractant containing water and from 0 to 70% by weight of alcohols; at least partially removing the extractant; b) extracting plant parts selected from cladodes, cladode parts and mixtures thereof using an extractant containing water and from 0 to 70% by weight of alcohols; at least partially removing the extractant; c) mixing together the extracts of step a) and b).

Abstract: Process for preparing a valerian extract formulation comprising the steps of: a) extracting radix valeriana officinalis with alcoholic-aqueous extractants to obtain a raw extract, said alcoholic-aqueous extractant containing from 10 to 50% by volume of alcohol; b) at least partially removing the alcoholic fraction from the raw extract to obtain a viscous extract; c) contacting the viscous extract with a hydrophobic adsorbing agent; d) separating the hydrophobic adsorbing agent to obtain a purified extract; e) converting the purified extract to a valerian extract formulation using pharmaceutically acceptable auxiliary agents.
