Anthocyanin pigments in the berries of baguaçu (Eugenia umbelliflora Berg), a tropical fruit fromBrazil, were extracted with 0.1% HCl in ethanol, and the crude anthocyanin extract was purified byAmberlite XAD-7 open-column chromatography. Six major anthocyanins were isolated by preparativeHPLC, and their chemical structures were identified by spectroscopic methods (TLC, UV-vis, MS,and 1H NMR). Delphinidin 3-O-
-glucopyranoside, cyanidin 3-O--glucopyranoside, petunidin 3-O--glucopyranoside, pelargonidin 3-O--glucopyranoside, peonidin 3-O--glucopyranoside, and malvidin3-O--glucopyranoside were identified. On the basis of chromatographic data the total anthocyanincontent was 342 mg/100 g of fresh baguaçu berries. Therefore, the concomitant presence of sixanthocyanins in a single plant species makes this product promising as a new pigment source.Keywords: Eugenia umbelliflora Berg; baguaçu; anthocyanins; natural colorants; 1H NMR
