Abstract:
The present invention relates to an improved multi-step method for preparing an extract from ginkgo biloba having a reduced content of 4′-O-methyl pyridoxine and/or biflavones, wherein the depletion is carried out by filtration over an adsorber resin and/or an ion exchanger and the substances to be removed are retained on the resin. The invention further relates to an extract from ginkgo biloba having a reduced content of 4′-O-methyl pyridoxine and/or biflavones, which is obtainable by the method according to the present invention, as well as to its use.
