Prenylated Flavonoids of Genus Epimedium: Phytochemistry, Estimation and Synthesis

Abstract

AbstractPrenylated flavonoids are the chemotaxonomic markers of genus Epimedium. Icariin, epimedin A, B and C are the main bioactive principles found in Epimedium spp. The chemical and pharmacological studies of a good number of prenylated flavonoids isolated from Epimedium species are reported in literature but their biosynthetic pathways have been explored to a limited extent only and remained ambiguous for a long time. In this review, an in‐depth and extensive coverage of Epimedium prenylated flavonoids is reported from 2012 to 2022 using SciFinder database for literature retreival. The review covers occurrence, synthesis, biosynthesis and quantification of prenylated flavonoids of genus Epimedium.
