An LC-DAD Fingerprinting Method for Alkaloids, Flavonoids and Styrylpyrones from Cryptocarya mandioccana

Abstract

An LC-DAD method has been developed in order to evaluate qualitatively and quantitatively quaternary aporphine alkaloids, flavonoid glycosides and styrylpyrones, which are the main secondary metabolites of leaves from C. mandioccana. The chromatographic method was validated considering both internal and external standard quantification methods and showed good performances in terms of selectivity, linearity, precision (repeatability and intermediate precision), limit of detection, limit of quantification, accuracy and stability.
