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.
