Resumo

The grumixama (Eugenia brasiliensis Lam.), also known as Brazilian cherry, is a fruit native to Brazil. This study identified the flavonoids in the flesh and seeds and ellagitannin in the flesh of purple and yellow varieties. The physicochemical characteristics and antioxidant capacity of these fruits were also evaluated. Anthocyanins and flavonols were found in high levels in the flesh of purple (32-180 mg 100 g(-1) FW) and yellow grumixama (13-41 mg 100 g(-1) FW), respectively. The major flavonoids identified were cyanidin 3-glucoside and quercetin aglycone. Furthermore, ellagitannins were found in high levels in the flesh of purple (82-243 mg ellagic acid equiv 100 g(-1) FW) and yellow grumixama (92 mg ellagic acid equiv 100 g(-1) FW) and seeds (2220-2905 mg ellagic acid equiv 100 g(-1) FW). The ellagitannin profiles of both varieties were first characterized in which pedunculagin isomers, strictinin isomers, and ellagic acid galloyl hexoside were the major ellagitannins identified. In summary, both varieties of the grumixama fruit as well as the seeds could be good sources of bioactive compounds, mainly ellagitannins. (AU)
