Identificação de antocianidinas em acerolas do Banco Ativo de Germoplasma da Universidade Federal Rural de Pernambuco

Abstract: RESUMOAs antocianinas, pigmentos responsáveis pela cor vermelha da acerola madura, foram extraídas e purificadas de 12 genótipos cultivados no Banco Ativo de Germoplasma da Universidade Federal Rural de Pernambuco, com o objetivo de determinar a sua composição. As antocianinas e suas respectivas agliconas, obtidas pela hidrólise ácida, foram separadas por cromatografia líquida de alta eficiência (CLAE) usando uma coluna de fase reversa (C 18 ). A identificação foi realizada pela ordem de eluição e pelos tempos… Show more

“…Due to the need for identifying promising genetic material, the Federal Rural University of Pernambuco -UFRPE established, in June 1998, an acerola Active Germoplasm Bank (AGB). The red color of this ripe fruit is due the anthocyanins content and Lima et al (2006) reported the presence of two aglycons which were identified as cyanidin and pelargonidin. The total anthocyanin content from these genotypes varied from 64.6 to 6.4 mg.100 g -1 of ripe fruits pulp (LIMA; MELO;GUERRA, 2007).…”

“…Anthocyanin is in the form of glycoside while anthocyanidin is known as the aglycone [ 4 ]. The anthocyanins are conjugated anthocyanidins and six of them (i.e., pelargonidin, cyanidin, delfinidin, petunidin, peonidin, and malvidin) are commonly found in berries [ 5 ], which differ in number of hydroxyls and the degree of methoxyls [ 6 ]. Glycoside formation and the greater presence of methoxyl groups generally give a more reddish color and greater stability to oxidation and heat than increased hydroxylations, which in turn provide a predominance of pink and blue [ 7 ].…”

“…As antocianinas encontradas em alimentos são derivadas das agliconas pertencentes aos seguintes pigmentos básicos: malvidina, delfinidina, petunidina, peonidina, cianidina e pelargonidina, as quais diferem entre si quanto ao número de hidroxilas e ao grau de metoxilas presentes no anel B (LIMA et al, 2006). São oxidadas na presença de radicais livres, gerando um radical menos reativo e mais estável, estabilizando as espécies reativas de oxigênio por meio de sua reação com o componente reativo do radical; esse fato acontece devido ao alto poder de reação do grupo hidroxila das antocianinas com o radical torna-o inativo (NIJVELDT et al, 2001).…”
