| ABSTRACT The properties of oil-resin of copaiba, Copaifera multijuga are commonly mentioned in the literature, but there are few studies on extracts from its stem bark. We evaluated the antioxidant effects of ethanolic (EE) and ethyl acetate (EA) crude stem bark extracts from copaiba and compared them to rutin in a paracetamol (PCM)-induced oxidative stress model in mice. All test comparisons differed significantly. Hepatic catalase (CAT) and glutathione-S-transferase (GST) activity decreased in the PCM group, and there was an increase of protein carbonyls in the liver, kidney and brain. However, the protein carbonyls decreased in the liver for the PCM + EE group, in the kidneys for the PCM + EA and PCM + Rutin groups, and in the brain for all treatments.... |

| This study evaluated the morphological variation (total and commercial height, and diameter at 1.3 m above ground level - DBH) and environmental variables (slope, distance to water bodies, solar orientation, termites, tree damage and elevation) which influence production of oleoresin by Copaifera paupera (Herzog) Dwyer in southwestern Amazon. The present study was conducted at the experimental forest of Embrapa Acre, Rio Branco, Acre State, Brazil. Forty-seven trees with DBH ≥ 40 cm were mapped, of which 21.3% produced oleoresin immediately after being drilled and 53.2% produced oleoresin after 5 to 7 days, totaling 74.5% productive trees. The site slope was the only variable that significantly influenced oleoresin production; the greater the slope, the... |

| ABSTRACT Copaifera multijuga, commonly known as copaiba, is popularly used in the form of tea for various conditions due to the presence of antioxidant substances in its composition, which protect cells against damage caused by free radicals. Its oleoresin is also used as an anti-inflammatory and antitumoral agent. The present study investigated the antioxidant effect of the ethanolic extract of copaiba stem bark on Swiss mice inoculated with solid Ehrlich tumors. Mice were inoculated subcutaneously with 1x106 Ehrlich’s tumor cells and treated via gavage with ethanolic extract of copaiba for thirty days, with doses varying between 100 and 200 mg kg-1. Biochemical analyses of enzymatic antioxidants [superoxide dismutase (SOD), catalase (CAT),... |

| A copaíba, árvore muito importante na vida de ribeirinhos e de povos que vivem em áreas de floresta da região Norte, pode estar ameaçada por práticas que não são as mais adequadas para a retirada de seu óleo. Este produto é apreciado pelos benefícios que traz à saúde humana, além de ser muito valorizado na fabricação de medicamentos e de outros produtos. No entanto, algumas árvores de copaíba já deixaram de produzir óleo ou estão morrendo porque foram cortadas ou furadas de forma errada. Esta situação prejudica as pessoas que vivem da exploração desta espécie florestal, pois compromete a produção do óleo, acabando com as chances de se ter uma produção regular. A copaíba é uma das espécies florestais cujo uso sustentável permite geração de renda por meio da... |
