Calogênese e teores de fenóis e tatinos totais em barbatimão [stryphnodendron adstringens (mart.) coville]

Abstract: RESUMOAtualmente, culturas de células ou de suspensões celulares têm sido frequentemente empregadas para produzir fitoterápicos com maiores concentrações de princípios ativos. O barbatimão é uma importante espécie medicinal do Cerrado, com taninos nas cascas do caule. Objetivando-se induzir calos em barbatimão e avaliar os teores de fenóis e taninos totais, explantes foliares foram inoculados em meio MS suplementado com 30 g L -1 sacarose e acrescidos de 2,4-D (0; 4,52; 9,05; 18,10 µM ) e BAP (0; 4,44; 8,88; … Show more

“…In this sense, the genus Stryphnodendron Mart. (“barbatimão”) is known for its numerous uses: the extracts from the stem bark are rich in tannins [ 9 ] and are used for curing various diseases, including leukorrhea, diarrhea, inflammatory processes, hemorrhages, hemorrhoids, conjunctivitis [ 10 ], malaria, fever, liver disorders, gonorrhea and urethritis [ 11 ], and wound healing [ 12 ]. The medicinal uses recognized for this genus are largely derived from biological activity studies, and not through ethnobotanical studies.…”

“…(Nery et al 2008) e Stryphnodendron adstringens (Mart.) Coville (Castro et al 2009), pois apresenta altos níveis de nitrogênio e potássio em concentrações superiores a dos outros meios utilizados neste trabalho, além de ser o único a possuir nitrogênio em forma de nitrato de amônio. Contudo, para muitas espécies lenhosas, o meio MS integral não se mostra satisfatório, com composições mais diluídas dos sais apresentando melhor desempenho (Grattapaglia & Machado 1998).…”
