Title (EN) EXTRACTIVE ANALYTICAL METHOD FOR TANNINS DETERMINATION ON RAW MATERIALS AND PLANT PRODUCTS
(FR) PROCÉDÉ EXTRACTIF/ANALYTIQUE POUR LA DÉTERMINATION DE TANINS DANS DES MATIÈRES BRUTES ET DES PRODUITS VÉGÉTAUX
(PT) MÉTODO EXTRATIVO-ANALÍTICO PARA DETERMINAÇÃO DE TANINOS EM INSUMOS E PRODUTOS VEGETAIS
Abstract: front page image
(EN)The present invention relates to an extractive-analytical method for determining tannins in raw materials and/or plant based products. In its broadest sense, it refers to the analytical determination of tannins starting with a pre-purifying stage intended to analyze monomers, independent of the total amount of phenols. The invention improves upon the chromatographic profile, making possible the separation and the quantification of tannins in raw materials and plant based products for analytical and preparative assessment. The method can be used for quality control in the food, pharmaceutical, and phytotherapy industries that contain plant based species rich in phenols.
(FR)La présente invention concerne un procédé extractif/analytique pour la détermination de tanins dans des matières brutes et/ou des produits végétaux. Plus généralement, elle concerne la détermination analytique de tanins à partir d'une étape de pré-purification dirigée pour l'analyse de monomères, indépendante de la quantité de phénols totaux. L'invention permet d'améliorer le profil chromatographique, rendant possible la séparation et la quantification de tanins dans des matières brutes et des produits végétaux à l'échelle analytique et préparative. Le procédé peut être utilisé pour contrôler la qualité, dans les industries alimentaire et pharmaceutique, de produits phytothérapeutiques contenant des espèces végétales riches en agents phénoliques.
(PT)A presente invenção diz respeito a um método extrativo-analítico para determinação de taninos em insumos e/ou produtos vegetais. Em seu aspecto mais geral, se refere a determinação analítica de taninos a partir de uma etapa de pré-purificação direcionada para a análise de monõmeros, independente da quantidade de fenóis totais. A invenção proporciona melhoramento do perfil cromatográfico, possibilitando a separação e a quantificação de taninos em insumos e produtos vegetais em escala analítica e preparativa. O método pode ser utilizado no controle de qualidade em indústrias de alimentos indústrias farmacêuticas de fitoterápicos que contenham espécies vegetais ricas em fenólicos.
