Abstract: front page image
(EN)The present invention relates to a novel method for quantifying procyanidin and flavan-3-ols contained in natural products, foods and drinks, pharmaceuticals and/or cosmetics. The present invention provides a method for quantifying procyanidin (a generic name for a mixture of catechin n-mer; n ≥ 1) contained in test samples such as natural products, foods and drinks, pharmaceuticals and/or cosmetics, which comprises a) pretreating a test sample using a column to remove contaminants which affect the analysis of procyanidin and flavan-3-ol; and b) effecting high performance liquid chromatography (HPLC) to separate and quantify procyanidin and flavan-3-ols in the solution treated to remove contaminants during the above pretreatment step a).
(FR)Un nouveau procédé de quantification de procyanidine et de flavane-3-ols contenus dans les produits, les aliments, les boissons, les médicaments et/ou les cosmétiques naturels. Ce procédé de quantification de la procyanidine, un nom générique pour un mélange de cathécine n-mère; n = 1) contenu dans des échantillons d'épreuve, notamment des produits, des aliments et des boissons, des médicaments et/ou des cosmétiques naturels consiste à a) prétraiter un échantillon au moyen d'une colonne afin d'en retirer les polluants affectant l'analyse de procyanidine et flavane-3-ol; et b) effectuer une chromatographie liquide haute performance (HPLC) afin de séparer et quantifier la procyanidine et les flavane-3-ols dans la solution traitée afin d'en supprimer les polluants pendant le pétraitement de l'étape a).
