Extraction method for determination of tannins in analytical inputs and / or plant products

摘要

Extraction method for determination of tannins in analytical inputs and / or plant products. The present invention relates to a method for the determination of tannin extraction analytical in inputs and / or plant products.In its most general, refers to the analytical determination of tannins from a stage of pre purification directed to the analysis of monomers, independent of the amount of total phenols. The invention provides improvement of chromatographic profile, enabling the separation and quantification of tannins in raw materials and plant products in analytical and preparative scale.
