Resumo: In this study, the main chemical components of Moquinia polymorpha (LESS.) DC. (candeia or cambará) wood were investigated. This wood is native in the Southern region of Minas Gerais - Brazil.  The chemical composition was:  47.5% of α-cellulose, 25.4% of A and B hemicelluloses, 24.0% of lignin, 73.2% of holocellulose, 3.82% of ethanol:cyclohexane  (1:1, v v-1) extractives, 3.21% of ethanol extractives and 4.04%  of hot water extractives.  The volatile composition was mainly: α-curcumene, α-dihydroturmerone, β-dihydroturmerone, cedranol, 1-cyclopentyl-3-[2,4-dimethylphenyl]propane. The total phenols analysis was carried out on methanol:water (MW) and acetone:water (AW) extracts. The last one presented better yield. The total phenols were determined by Folin-Ciocalteau and the modified Prussian blue assays.  Folin-Ciocalteau yielded 0.93 mg g-1 of wood for MW extract and 1.56 for AW extract; modified Prussian blue yielded 2.74 mg g-1 of wood for MW extract and 4.42 for AW extract. Proanthocyanidins were determined by n-buthanol-acid and vanillin assays. The n-buthanol acid yielded 0.012 mg g-1 of wood for MW extract and 0.017 for AW extract; vanillin: 0.29 mg g-1 of wood for MW extract and 0.58 for AW extract. 3-deoxy-proanthocyanidins were not detected.

DC., conhecida como candeia ou cambará, nativa da região Sul de Minas Gerais. A composição química dessa madeira foi: 47,5% de α-celulose, 25,4% de hemiceluloses A e B, 24,0% de lignina, 73,2% de holocelulose, 3,82% de extrativos em etanol:cicloexano (1:1, v v-1), 3,21% em etanol e 4,04% em água quente. Nos compostos voláteis identificados, destacaram-se: α-curcumeno, α-diidroturmerona, β-diidroturmerona, cedranol, 1-ciclopentil-3-[2,4-dimetil-fenil]propano. A análise dos fenóis totais foi conduzida com base nos extratos metanol-água (MA) e acetona-água (AA), em que esse último apresentou maior rendimento. O teor de fenóis totais foi determinado pelos métodos Folin-Ciocalteau e Azul da Prússia modificado. No método Folin-Ciocalteau, foram encontrados 0,93 mg g-1 de madeira para o extrato MA e 1,56 para o extrato AA e no método azul da Prússia modificado, foram determinados 2,74 mg g-1 de madeira para o extrato MA e 4,42 para o extrato AA. O teor de proantocianidinas foi determinado pelos métodos da vanilina e n-butanol:ácido. No método n-butanol:ácido, foram encontrados 0,012 mg g-1 de madeira para o extrato MA e 0,017 para o extrato AA e, no método da vanilina, foram determinados 0,29 mg g-1 de madeira para o extrato MA e 0,58 para o extrato AA.
