On the need to improve the safety and quality control of extracts from the leaves of ginkgo biloba

Cover Page

Abstract


The issue of safety and quality examination of natural food additives and medicinal products is considered on the example of extracts from leaves of ginkgo biloba - nootropics, the most popular in the world both in terms of consumption and scientific interest. The requirements to the composition of preparations and methods of their control are characterized. A new original methodology for the determination of the content in commercial preparations of individual terpene lactones, flavonoglycosides of various groups and their aglycones by 1H NMR is proposed. A number of adulterated and/or lowquality preparations have been identified. The ways of expertise improving are proposed, including the definition of the minor components content.
