Resumo: | The fruit of Myrciaria dubia is rich in bioactives, these have a high content of ascorbic acid and phenolic compounds, for this reason, the fruit has been gaining prominence for its antioxidant capacity. The aim of this study was to evaluate whether different extracts obtained from M. dubia fruit peels influence the antioxidant activity. 70% hydroalcoholic (EHA) and 10 and 20% glycolic extracts (EG10 and EG20) were obtained from bark from a moderately coarse powder with loss on desiccation of 13.53%, total ash of 1.95%, ash insoluble in acids of 0.057%, pH 2.53±0.05 and swelling index of 1.1ml. The extracts were characterized as to the content of ascorbic acid and total polyphenols and the antioxidant activity determined by DPPH and ABTS+. The EHA showed 7011±39 mg/100ml of ascorbic acid and 7.75% of total polyphenols, while in the EG10 and EG20 the ascorbic acid content was 3034±0 and 6137±0 mg/100mL and total polyphenols of 2 .65 and 3.55% respectively. The extracts showed DPPH antioxidant capacity with IC50 of 11.80, 48.95 and 25.26 µg/mL and ABTS+ of 92.91±0.205, 74.59±0.259 and 77.21±1.34% in the EHA extracts, EG10 and EG20, respectively. The extracts have important contents of bioactive compounds, however, the solvent influenced the content and biological activity, with EHA having the highest content of bioactives, which also reflected in its greater antioxidant capacity. |

El objetivo de este estudio fue evaluar si diferentes extractos obtenidos de la cáscara del fruto de M. dubia influyen en la actividad antioxidante. Se obtuvieron extractos hidroalcohólicos al 70% (EHA) y glicólicos al 10 y 20% (EG10 y EG20) de la corteza a partir de un polvo moderadamente grueso con pérdida por desecación del 13,53%, cenizas totales del 1,95%, cenizas insolubles en ácidos del 0,057%, pH 2,53±0,05 e índice de hinchamiento de 1,1 ml. Los extractos se caracterizaron en cuanto al contenido de ácido ascórbico y polifenoles totales y la actividad antioxidante determinada por DPPH y ABTS+. El EHA mostró 7011±39 mg/100ml de ácido ascórbico y 7,75% de polifenoles totales, mientras que en el EG10 y EG20 el contenido de ácido ascórbico fue de 3034±0 y 6137±0 mg/100mL y polifenoles totales de 2,65 y 3,55%. respectivamente. Los extractos mostraron capacidad antioxidante DPPH con IC50 de 11.80, 48.95 y 25.26 µg/mL y ABTS+ de 92.91±0.205, 74.59±0.259 y 77.21±1.34% en los extractos EHA, EG10 y EG20, respectivamente. Los extractos tienen contenidos importantes de compuestos bioactivos, sin embargo, el solvente influyó en el contenido y la actividad biológica, siendo el EHA el de mayor contenido de bioactivos, lo que también se reflejó en su mayor capacidad antioxidante.O fruto de Myrciaria dubia é rico em bioativos, este apresenta alto teor de ácido ascórbico e compostos fenólicos, por este motivo, o fruto vem ganhando destaque pela sua capacidade antioxidante. O objetivo deste estudo foi avaliar se diferentes extratos obtidos de cascas do fruto de M. dubia influencia na atividade antioxidante. Extratos hidroalcoólico 70% (EHA) e glicólicos 10 e 20% (EG10 e EG20) foram obtidos de cascas a partir de um pó moderadamente grosso com perda por dessecação de 13,53%, cinzas totais de 1,95%, cinzas insolúveis em ácidos de 0,057%, pH 2,53±0,05 e índice de intumescência de 1,1ml. Os extratos foram caracterizados quanto ao teor de ácido ascórbico e polifenóis totais e a atividade antioxidante determinada por DPPH e ABTS+. O EHA apresentou 7011±39 mg/100ml de ácido ascórbico e 7,75% de polifenóis totais, enquanto que, nos EG10 e EG20 o teor de ácido ascórbico foi 3034±0 e 6137±0 mg/100mL e de polifenóis totais de 2,65 e 3,55% respectivamente.
