Resumo: | The effects of the extraction system (50% methanol or 50% methanol pH 2.0), volume/material ratio, temperature, time and extractions with 70% acetone were evaluated in the total phenolic compounds (TPC) extraction and in antioxidant activities (AA) using FRAP and ABTS assays in guava fruit. The best yield was obtained when 0.5 g of guava were extracted first with 20 mL 50% methanol and then four times with 20 mL 70% acetone during 30 min at 50 °C. Among the different trials guava fruit exhibited high levels of AA as well as TPC. |
