title: Tissue distribution of anthocyanins in rats fed a blackberry anthocyanin-enriched diet.
abstract: Anthocyanins are natural dietary pigments that could be involved in various health effects. The aim of this study was to investigate the distribution of anthocyanins to various organs (bladder, prostate, testes, heart and adipose tissue) in rats fed with a blackberry anthocyanin-enriched diet for 12 days. Identification and quantification of anthocyanins were carried out by HPLC-DAD. The urinary excretion of total anthocyanins (native anthocyanins and their metabolites) was low (0.20 +/- 0.03%, n = 8). Proportions of anthocyanin derivatives (methylated anthocyanins and glucurono-conjugated derivatives) differed according to the organ considered. The bladder contained the highest levels of anthocyanins followed by the prostate. Prostate, testes and heart contained native cyanidin 3-glucoside and a small proportion of cyanidin monoglucuronide. Cyanidin 3-glucoside and methylated derivatives were present in adipose tissue. Thus, anthocyanin feeding in rats resulted in a wide distribution of anthocyanin derivatives to several organs. Identification of target tissues of anthocyanins may then help to understand the mechanisms of action of anthocyanins in vivo.
