“…Some studies have reported a high correlation between the antioxidant activity of plant extracts with the content of phenolic compounds (Sun & Ho, 2005;Singh et al, 2007). In this study, the results showed a high degree of correlation (r 2 = 0.97) between total phenolic content and the AAI.…”

Recebido para publicação em 09/11/2011 Aceito para publicação em 04/06/2013 RESUMO: Foram avaliados os efeitos de métodos de extração e de solventes sobre o rendimento de extrato, conteúdo de fenólicos totais, atividade antioxidante, e composição dos compostos fenólicos de Xanthium strumarium L. A atividade antioxidante foi determinada pelo método do radical 2,2-difenil-1-picrilhidrazila (DPPH), e a composição dos compostos fenólicos foi determinada por cromatografia líquida de alta eficiência e por espectrometria de massas com ionização por electrospray. Todos os resultados foram afetados pelo método de extração e, principalmente pelo solvente utilizado, sendo que os melhores resultados foram obtidos com o solvente metanol. Os extratos metanólico e etanólico apresentaram forte ação antioxidante e os principais compostos fenólicos encontrados nos extratos foram os ácidos ferúlico e clorogênico. Palavras-chave:Xanthium strumarium, carrapicho, atividade antioxidante, compostos fenólicos, IAA ABSTRACT: Efeito de métodos de extração de compostos fenólicos de Xanthium strumarium L. e suas atividades antioxidantes. The effect of extraction methods and solvents on overall yield, total phenolic content, antioxidant activity, and the composition of the phenolic compounds in Xanthium strumarium extracts were studied. The antioxidant activity was determined by using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), and the composition of the phenolic compounds was determined by HPLC-DAD and LC/MS. All results were affected by the extraction method, especially by the solvent used, and the best results were obtained with the methanol extract. The methanolic and ethanolic extracts exhibited strong antioxidant activity, and the chlorogenic and ferulic acids were the most abundant phenolic compounds in the extracts.

“…The second which are reducing agents, have a lower redox potential than the drug or adjuvants which they are intended to protect and are therefore, more readily oxidized. The third are antioxidant synergist, which usually have little antioxidants effect themselves but probably enhance the action of true antioxidants by reacting with heavy ions, which catalyze oxidation [68]. The aqueous and acetone extract of S. hermonthica was further separated into aqueous and ethyl acetate fraction and assayed for their in vitro antioxidants properties using 2,2-diphenyl-1-picryl hydrazyl (DPPH).…”

In the present work methanolic and water extracts of 19 medicinal plants, commonly used in Sudanese folk medicines against gastrointestinal tract, infectious diseases were investigated for their antioxidant activity. Antioxidant assays were carried out by using different in vitro models such as DPPH (2, 2-diphenyl-1picrylhydrazyl) radical scavenging and Iron chelating activity. Methanolic and water extracts of Punica granatum showed the highest total antioxidant activity of 71±0.03 and 73±0.01 respectively. The antioxidant activities of water extracts were poor when compared to the methanol extract. The iron chelating power of methanol and aqueous extracts of Commiphora myrrha 58±0.01 and Azadirachta indica 57±0.20 respectively.
