Patent ID: 7981294

Claim:
A process for extracting one or more metabolites from an organic material, comprising (1) an extraction step, comprising (a) extracting an organic material with a first extraction and a second extraction, wherein (i) the first extraction comprises extracting with a monophasic mixture of 50% by volume to 90% by volume of methanol and 50% by volume to 10% by volume of water and, optionally, 0% by volume to 40% by volume of a further solvent or solvent mixture; and (ii) the second extraction comprises extracting with a monophasic unpolar solvent or solvent mixture, and (b) combining the extracts obtained from step (i) and step (ii) to form one phase; and (2) an analyzing step, in which one or more metabolites are determined; wherein in step (a), the first extraction and the second extraction are prepared in parallel or in succession.
