EnglishThe high intensity ultrasound-assisted extraction (HIU) is one of the most simple, quick and efficient techniques for the extraction of phenolic and other antioxidant compounds from plants. This is the first application of HIU for the extraction of these compounds from goldenberry fruit. The HIU and conventional extraction techniques showed similar results regarding to phenolic compounds and antioxidant capacity. However, the time required for HIU extraction (5min) was 24 times lower than conventional extraction (120min). Phenolic compounds reported were chlorogenic acid, caffeic acid and rutin. In vitro cytotoxicity assays were used for evaluation of extracts and the results showed that in a wide range of concentration, the extract maintains cell viability, thus indicating the possibility to use it as food with safety.

Entretanto, o tempo necessario na HIU (5min) foi 24 vezes menor que na extracao convencional (120min). Os compostos fenolicos encontrados foram acido clorogenico, acido cafeico e rutina. Ensaios de citotoxicidade in vitro foram usados para avaliacao dos extratos e os resultados demonstraram que, em ampla faixa de concentracao, o extrato mantem a viabilidade celular, indicando assim possivel seguranca para utilizacao em alimentos.
