The effect of solvent extraction on antioxidant properties of apricot fruit

Abstract

Two solvent extraction procedures were used to investigate the extraction efficiency in terms of total antioxidant capacity and\ud total phenols in apricot fruit. Samples were either sequentially extracted with aqueous ethanol (ethanol/water 80% v/v) and\ud tetrahydrofuran or directly extracted with tetrahydrofuran. Each extract was analyzed for total antioxidant capacity by the\ud Trolox Equivalent Antioxidant Capacity (TEAC) assay and total phenols by the Folin-Ciocalteu assay. The results showed\ud that using sequential solvent extraction, the majority (85%) of the total antioxidant capacity and total phenols was due to\ud hydrophilic compounds. In tetrahydrofuran direct extractions, the total antioxidant capacity and total phenols were higher than\ud values obtained with aqueous ethanol and the sum of results obtained from sequential extracts for either total antioxidant\ud capacity or total phenols was similar to the tetrahydrofuran-extract antioxidant values. A linear correlation between total\ud antioxidant capacity and total phenols was found and was independent of the solvent extraction method. In conclusion, the\ud choice of solvent is related to the antioxidant potential of fruit and depends on the food hydrophilic/lipophilic composition

Antioxidant activity, total phenolic content and flavonoid concentrations of different plant parts of Teucrium polium L. subsp. polium

“…linear correlation between the values of phenolic content and antioxidant activity [25]. The difference in morpho-anatomical structure and physiological activity of different plant parts contribute to varying phenolic content and antioxidative activity values.…”

Antioxidant Capacity and Phenolics Content of Apricot (Prunus armeniaca L.) Kernel as a Function of Genotype

“…The study by Scalzo et al [5] found no correlation between antioxidant capacity and phenolic content whereas the opposite was found by Drogoudi et al [12]. A strong [26], nectarines, peaches and plum was reported [29].…”

“…Higher ferric reducing antioxidant potential with acetone suggests that apricot kernel contains significantly higher lipophilic than hydrophilic antioxidants. Higher lipophilic antioxidants in kernel in contrast to apricot fruit [5,26] could be due to higher phenolic content in kernel oil. Similar results have been reported in embryo extracts of Melicoccus bijugatus Jacq.…”

A high correlation indicating for an evaluation of antioxidant activity and total phenolics content of various chilli varieties

“…Prior to the determination of the antioxidant activity and total phenolics content, the optimum conditions for extraction methods of the antioxidants are needed. Some typical solvents have been used for the extraction of antioxidants including methanol, ethanol, acetone, water, acetonitrile, tetrahydrofuran, hexane, ethyl acetate (Leccese et al 2011;Sang et al 2014;Nguyen et al 2015). A large number of extraction techniques for the antioxidants have also been developed for analysis of the antioxidants including ultrasound assisted extraction (UAE), microwave assisted extraction (MAE), supercritical fluid extraction (SFE), pressurized fluid extraction (PFE), accelerated solvent extraction (ASE) and enzyme assisted extraction (Chen et al 2015;Ranic et al 2014).…”
