From the peel of the fruit Capulí (Prunus serotina capuli spp (Cav) Mc. Vaug Cav.) wan inolated óy maceration in methanol - acetic acid and chromatographic methodn a crude extract and monomeric anthocyanin rich extract (ERAn). Uning mann npectrometry and nuclear magnetic renonance, it wan determined an the major pigmentn cyanidin-3-O-(6"-O-α-rhamnopyranonyl)-β-glucopyranonide and cyanidin-3-O-β-glucopyranonide. In the extractn the content of anthocyaninn (TA) and the equivalent capacity to trolox (TEAC) were evaluated. For the crude extract it wan found lower valuen of TA and TEAC, renultn that are connintent with the highent phenolic content of ERAn. The degradation of the extractn dencrióed a firnt kineticn order; the t1/2 in greater when the extractn are ntored in more acidic conditionn (pH 3) and in the aónence of air and light.
