1. A method of removing pesticides from extracts of Ginkgo biloba, which comprises subjecting the extract obtained by conventional methods to the following steps: a) liquid-liquid extraction to obtain a medium polarity fraction containing ginkgo terpenes and pesticides not removed by hexane and a high polarity fraction containing ginkgo flavone glycosides； b) crystallization from the middle polarity fraction obtained in stage a), with the formation of an intermediate product with a ginkgolide content of at least 50%； c) crystallization from the residual solution ora obtained in stage b), with the formation of an intermediate product with a bilobalide content of at least 50%； d) mixing the high polarity fraction obtained in stage a) with the intermediate product of ginkgo terpenes and the intermediate product of bilobalide obtained in stages b) and c ) .2. The method according to claim 1, wherein the extraction of stage a) is carried out with a water-immiscible solvent selected from esters, chlorinated hydrocarbons, mixtures of hydrocarbons and alcohols, ketones and mixtures of ketones and alcohols. The method according to claim 2, wherein the solvent is an ester having from 2 to 8 carbon atoms. The method according to any one of claims 1 to 3, in which the crystallization of ginkgo terpenes is carried out in mixtures of water and C-Alcohols. The method according to any one of claims 1 to 3, wherein the crystallization from the terpene-enriched fraction of step c) is carried out in water or in a mixture of water and C-Alcohols. The extract obtained by the method according to any one of claims 1 to 5, having a given ratio of ginkgo terpenes.1.
