Determination of phytochemicals of Turkish fig genetic resources

The rise of consumer interest in functional food make it necessary to determine the total phenolic (TP) and antioxidant activity (AOA) of the fig accessions in Türkiye. In this study, 236 fig accessions were analayzed for various metabolites such as phenolic compounds, total phenols (TP), total anthocyanins (TA), total flavonoids (TF), and total antioxidant capacity (TAC). The results showed that routine (44.34 ±8.78 mg kg–1 FW) was dominant phenolic compound in the fruits of ‘Bursa Siyahı’ variety, followed by epicatechin (27.76 ±1.12 mg kg–1 FW), syringic acid (4.57 ±2.20 mg kg–1 FW) and chlorogenic acid (4.39 ±0.20 mg kg–1 FW). Among the samples analysed, it was determined that the accession with the highest TPC (189.0 mg GAE 100 g–1 FW) and AOA (688.6 µmol troloks 100 g–1 FW) was ‘Kepek’ (TR 532). Also, it was determined that the accession with the highest anthocyanin content (512.3 mg cyn-3-glu kg–1 FW) was ‘Siyah’ (TR 230). ‘Kepek’ (TR532), ‘Siyah’ (TR 230), ‘Divrekkara’ (TR1101) and ‘Siyah Kış’ (TR1088) are generally not very cultivated accessions. These accessions have an important potential due to the continuous rise of interest in food with high AOA all around the world.
