Variation in Physical-Chemical Parameters and Phenolic Compounds in Fruits of Four Calafate Clones

Calafate (Berberis microphylla G. Forst) is an evergreen shrub with blue berries that grows naturally in Patagonia, South America. It has beneficial nutraceutical characteristics for human health. The objective of the research was to evaluate effect different harvest dates calafate clones south-central zone Chile on polyphenolic content, antioxidant capacity, quality parameters and fruit yield. To meet this objective, during three consecutive years, four wild located town San Ignacio, Chile, were selected. Where a period established from 110 140 days after full bloom (DAFBs), each harvests carried out used following measurements: determination anthocyanin concentration polyphenols, phenolic compounds, soluble solids, total titratable acidity, pH, yield quality. Among main results, it can be highlighted clone 2 one obtained highest 38.0 °Brix at DAFBs. Together, content polyphenols anthocyanins, 1121 g GAE kg−1 fw 714 cy-3-glu 100 g−1 fw, respectively.
