Isolation of catechins from Cycas armstrongii Miq. of an Egyptian origin

Abstract

The phytochemical investigation of Cycas armstrongii Miq. leaves and twigs using different chromatographic techniques led to the isolation of three catechin monomers; catechin (1), epicatechin (2), and epigallocatechin-3-gallate (3), for the first time from this species. The chemotaxonomic significance of the isolated compounds is discussed in the rest of this article.
