Abstract

Bromelia laciniosa is a native species of the Caatinga biome, popularly known as “macambira” and “macambira de porco”. This paper describes the isolation and structural characterization of the first chemical constituent isolated from the leaves of B. laciniosa, an unprecedented flavonoid in the Bromeliaceae family. The structure was established as 5,7-dihydroxy-3,3',4'-trimethoxyflavone (quercetin 3,3’,4’-trimethyl ether) on the basis of mass spectrometry and 1D and 2D nuclear magnetic resonance (NMR) experiments and further confirmed by comparison with available data in current literature.

 

Key words: Bromelia laciniosa, Bromeliaceae, flavonoid, medicinal plants, Caatinga.
