Avaliação das variáveis analíticas do método de Folin-Ciocalteu para determinação do teor de taninos totais utilizando como modelo o extrato aquoso de folhas de psidium guajava L. Evaluation of analytical variables of the Folin-Ciocalteu method for the quantitation of the total tannins content using a Psidium guajava L. leaves aqueous extract as a model

<abstract language="eng">The main analytical variables of a modified Folin-Ciocalteu method were studied by UV-Vis and gradient HPLC-PDA methods, using purified (PC) and technical grade (TGC) casein. Rutin and an aqueous extract of Psidium guajava L. leaves were used as models. The b...
