ROMEROA, Ruth S.; DOMINGUEZ, Gilberto  y  GUZMAN, Deysi R.. Quantification of polyphenols in leaves of cat's claw Uncaria Tomentosa (Willd. ex Schult) D.C. from three locations in Ucayali. Rev. Soc. Quím. Perú [online]. 2014, vol.80, n.3, pp.174-182. ISSN 1810-634X.

Cat's claw (Uncaria tomentosa Willd. ex D.C.), Rubiaceae family, is a vine which is used, traditional and commercially, the crust in several towns in the Peruvian Amazon and other parts of South America: because of their actions antiinflammatory, antimicrobial, immunostimulatory, antioxidant, etc. This study aimed to quantify total polyphenols present in the leaves of "cat's claw" Uncaria tomentosa from the same clone set in three locations from Ucayali. The botanical material was collected in November 2009, in Tres de Octubre, El Porvenir and Nuevo Ucayali, covering the districts of Padre Abad Province Irazola and Coronel Portillo, Ucayali department. With the leaf samples was extracted by percolation method using as solvent an alcohol solution in a 1:25 ratio and solvent leaves. The extracts obtained were subjected to qualitative tests (phytochemical), which were detected as metabolites: alkaloids, fatty compounds, flavonoids, sugars, condensed tannins and saponins, and allowed to determine the quantitative content of polyphenols in the extract and the percentage condensed tannins present in the samples.
