Teores de fenóis totais e taninos nas cascas de angico-vermelho (Anadenanthera peregrina)

Abstract: RESUMOEste trabalho teve como objetivo quantificar fenóis totais e taninos nas cascas de angicovermelho (Anadenanthera peregrina) em diferentes classes de diâmetro, além de comparar duas metodologias de quantificação de fenóis. Foram coletadas cascas de 35 árvores, distribuídas em sete classes diamétricas. As cascas foram secas ao ar livre, trituradas e peneiradas, sendo utilizado o material retido na peneira de 60 mesh. Para a extração dos fenóis, utilizou-se metanol:água (50%). O doseamento de fenóis totais … Show more

“…The determinations of total organic carbon (TOC) and total nitrogen (TN) of the culture medium were performed in a total organic carbon analyzer (TOC-L Shimadzu) equipped with a total nitrogen measuring unit (TNM-L Shimadzu) and 8-port sampler (OCT-L Shimadzu). Total phenols were estimated as tannic acid equivalents, according to the Folin-Ciocalteau assay (Sartori et al, 2014). The physicochemical analyses of chemical oxygen demand (COD) and bio-chemical oxygen demand (BOD) were performed according to the procedure described by Eaton et al (2005).…”

“…Another species that stands out as a producer of tannins is Anadenanthera peregrina, popularly known as Curupay. The bark of this leguminous plant produces good yields of condensed tannins, a class of tannins widely found in nature and whose composition includes flavonoid units linked by carbon-carbon bonds that are difficult to break using hydrolyses, in addition to having a strong nucleophilic character (Pizzi, 1982;Sartori et al, 2014a). This is one of the reasons why the tannins of this species are suitable for use as raw material in the production of wood adhesives (Carneiro et al, 2009).…”

“…Anadenanthera peregrina is a leading species whose wood is very dense, hard, and of average texture (Lorenzi, 1998). The bark of the Curupay tree is one of the main non-wood industry products found in the Cerrado region, and its use for extraction of tannins is economically viable because they present various application, adding greater value to the bark, resulting in higher returns from this waste (Afonso, 2009;Sartori et al, 2014a).…”
