A Straightforward Procedure for the High-Yield Extraction of Tricin and Flavonoids from Ecuadorian <i>Huperzia brevifolia</i> (Lycopodiaceae).

ABSTRACT: Rich natural sources of the flavone tricin (5,7,4'-trihydroxy-3',5'-dimethoxyflavone; systematic IUPAC name: 5,7-dihydroxy-2-(4-hydroxy-3,5-dimethoxyphenyl)-4H-1-benzopyran-4-one) are actively sought since this compound is endowed with a broad spectrum of biological activities and its dietary supplementation has been considered as a colon cancer chemoprotectant and for the treatment of human intestinal polyps. This paper describes a straightforward procedure for the high-yield isolation of flavonoids and tricin from aerial parts of Huperzia brevifolia (Hook. & Grev.) Holub, which grows on the paramos of Southern Ecuador. Compared to existing procedures, this method requires limited organic solvent and no chromatographic separation. In brief, the selective separation of
