ABSTRACT:
The present invention relates to a process for extracting constituents from organic material, comprising the step of extracting with a monophasic mixture of 50% by volume to 90% by volume of methanol and 50 to 10% by volume of water and optionally 0% by volume to 40% by volume of a further solvent or solvent mixture.
