“…Thus removing H2O2 is very important for the protection of living systems 28 . The present finding were also endorsed by earlier workers Lau et al, (2004) and David et al, (2007) who reported that the several species of Mimosa had significant antioxidant property 29,30 . Correspondingly, Genest et al, (2008) also demonstrated that the n-hexane, dichloromethane (DCM) and methanol (MeOH) extracts of Mimosa pudica and Mimosa rubicaulis, two Bangladeshi medicinal plants, were also had free radical scavenging activity 31 .…”

“…22,23 A literatura reporta atividade antioxidante ao extrato metanólico de Byrsonima gardneriana A. Juss; 16 no entanto, não há relatos sobre o teor de fenólicos totais e atividade antioxidante do extrato etanólico bruto e das fases desta espécie. 17 A referida espécie não apresenta estudos sobre seus constituintes químicos descritos na literatura, destacando-se a importância de um estudo fitoquímico criterioso da mesma. Neste artigo reportamos o isolamento e a caracterização estrutural de cinco triterpenos, 3-oxo-5-ene-glutinona (1), taraxerona (2), friedelina (3), lupeol (4) e β-amirina (5), um flavonoide, (+)-catequina (6).…”

“…7,[13][14][15][16] Os radicais livres, na forma de espécies reativas de oxigênio (EROs) e espécies reativas de nitrogênio (ERNs), são uma parte integrante da fisiologia normal. 17 No entanto, as EROs exercem um papel importante nos processos degenerativos ou patológicos em várias doenças humanas, como o envelhecimento, 18 câncer, doenças coronarianas, doença de Alzheimer, 19 desordens neurodegenerativas, aterosclerose e inflamação.20 Substâncias antioxidantes em sistemas biológicos têm múltiplas funções, que incluem proteção contra danos oxidativos e prevenção dos danos causados pelas EROs. 21 As plantas podem ser uma fonte de ampla variedade de moléculas sequestradoras de radicais livres, como compostos fenólicos (ex.…”

“…The inability of LNS to also increase step climbing behaviour was probably as a result of the doses used or may reflect anxiolytic action via a different mechanism compared to that of the benzodiazepines. The anxiolytic activity observed in this experiment could be linked to its reported antioxidant properties (Takeda et al, 1999;David et al, 2007) as oxidative stress has been implicated in anxiety (Bouayed et al, 2009). …”
