Effect of conditions of solid-liquid extraction on the extractability of phenolic compounds from lyophilized fig fruits (Ficus carica L.)
In this work the influence of ethanol/water solvent (50-80%, v/v) and the temperature of extraction (25 80 °C) on the extractability of total phenols, total flavonoids and total proanthocyanidins from different fig fruits was investigated. The best extraction conditions (80%, v/v ethanol/water, 80 °C) obtained in the experiments with lyophilized Ficus carica L. cv. Šaraguja were used while performing the extraction of phenolic compounds from other fig varieties (Bružetka bijela, Crnica, Bjelica and Termenjača). The antioxidant activity was measured in all fig fruit extracts as well. It has been shown that two examined process parameters (ethanol/water solvent and the temperature) have statistically significant influence on the extraction of phenolic compounds. The highest extraction yield of phenolic compounds was found in fig variety Crnica while the lowest one was found in fig variety Bjelica. According to the results obtained in this study, fig fruit extracts can be considered as a natural source of phenolic compounds with good antioxidant activity.
