The first flavonoid isolated from Bromelia laciniosa (Bromeliaceae)

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) experime… Show more

“…Both species have medicinal applications and pharmacological activities (PFIRTER et al, 1973;ALBUQUERQUE et al, 2007;AGRA et al, 2007;CARVALHO et al, 2010;OLIVEIRA-JÚNIOR et al, 2014) with the presence of flavonoids, tannins, saponins, steroids, and triterpenoids (RIBEIRO et al, 2006). Also ther is a study that demonstrates the existence of chemical compounds that have anticancer activities (LEWIS;HANSON, 1991).…”

“…Bromelia laciniosa and E. spectabile have different potential uses, ranging from use as ornamental plants to cultivated as a stock fence (BESSA, 1982;LIMA, 1996;ANGELIM et al, 2007), animal feed (BESSA, 1982;LIMA, 1996;NUNES et al, 2015;, human consumption (NASCIMENTO et al, 2012;JUVIK et al, 2017), medicinal properties, and pharmacological activities (PFIRTER et al, 1973;ALBUQUERQUE et al, 2007;AGRA et al, 2007;CARVALHO et al, 2010;OLIVEIRA-JÚNIOR et al, 2014), raw material for the manufacture of handicrafts and utensils, in addition to presenting an ecological relationship with vertebrates and invertebrates. The importance of these two species for the Brazilian Northeast population, macambira is reported in literary works, lyrics, visual arts, family surnames, people's nicknames, municipality name, villages, waterfalls, and this scientific journal.…”

“…Both are xerophilous and have morphological and physiological structures adapted to the semi-arid climate. Both species have several potentialities of use, ranging from ecological importance to use as ornamental plants, live fences, animal and human food, medicinal properties and pharmacological activities, raw material for the manufacture of handicrafts and utensils (NUNES et al, 2016;ALBUQUERQUE et al, 2007;ANGELIM et al, 2007;CARVALHO et al, 2010;NASCIMENTO et al, 2012;OLIVEIRA-JÚNIOR et al, 2014;JUVIK et al, 2017), among others.…”
