Resumo: Due to its chemical complexity, there are several methodologies for vegetable tannins quantification. Thus, this work aims at quantifying both tannin and non-tannin substances present in the barks of Mimosa tenuiflora and Acacia mearnsii by two different methods. From bark particles of both species, analytical solutions were produced by using a steam-jacketed extractor. The solution was analyzed by Stiasny and hide-powder (no chromed) methods. For both species, tannin levels were superior when analyzed by hide-powder method, reaching 47.8% and 24.1% for A. mearnsii and M. tenuiflora, respectively. By Stiasny method, the tannins levels considered were 39.0% for A. mearnsii, and 15.5% for M. tenuiflora. Despite the best results presented by A. mearnsii, the bark of M. tenuiflora also showed great potential due to its considerable amount of tannin and the availability of the species at Caatinga biome.

Neste sentido, o presente estudo teve como objetivo quantificar as substâncias tânicas e não-tânicas presentes nas cascas de jurema-preta (Mimosa tenuiflora) e de acácia-negra (Acacia mearnsii) por dois métodos distintos. A partir das partículas de casca de ambas as espécies, foram geradas soluções analíticas utilizando um extrator do tipo camisa de vapor, sendo a solução analisada pelos métodos de Stiasny e do pó de pele (não cromado). Para ambas as espécies, os teores de tânicos foram superiores quando analisados pelo método de pó de pele, atingindo 47,8 e 24,1% para A. mearnsii e M. tenuiflora, respectivamente. Pelo método de Stiasny, o teor de taninos condensados foi de 39,0% para A. mearnsii e 15,5% para M. tenuiflora. Apesar dos melhores resultados obtidos para a A. mearnsii, a casca de M. tenuiflora também apresentou grande potencialidade em função da considerável quantidade de tânicos e da disponibilidade da espécie no bioma Caatinga.Embrapa Florestas2021-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/98610.4336/2016.pfb.36.85.986Pesquisa Florestal Brasileira; v. 36 n. 85 (2016): jan./mar.; 61-69Pesquisa Florestal Brasileira; Vol. 36 No. 85 (2016): jan./mar.; 61-691983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/986/472Copyright (c) 2016 Leandro Calegari, Pedro Jorge Goes Lopes, Elisabeth de Oliveira, Darci Alberto Gatto, Diego Martins Stangerlinhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCalegari, LeandroLopes, Pedro Jorge Goesde Oliveira, ElisabethGatto, Darci AlbertoStangerlin, Diego Martins2021-11-17T13:34:26Zoai:pfb.cnpf.embrapa.br/pfb:article/986Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2021-11-17T13:34:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
