Identification, antioxidant and cytotoxic potentials of casticin in <I>Vitex agnus-castus</I> fruit from different geographical regions of Turkey
Abstract
Purpose: To evaluate the antioxidant and cytotoxic effects, and casticin contents of Vitex agnus-castus (VAC) fruit extract from five geographical regions of Turkey.
Methods: Casticin determination in VAC fruit extracts was performed using HPLC-DAD method. The method was validated for linearity, sensitivity, selectivity, accuracy and precision. The methanol extracts of the VAC fruits were analyzed for antioxidant effects using 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging capacity, metal-chelation capacity assay, radical cation scavenging capacity (ABTS•+), and total phenolic content. The cytotoxic potential of the extracts against NRK-52E and HeLa cells were determined using MTT and LDH assays.
Results: The casticin content of the extracts ranged from 0.048 and 0.152 %. Total phenol content was in the range of 36.67 ± 0.7 to 74.20 ± 1.02 mg gallic acid equivalent (GAE)/100 mg of extracts. High-tomoderate antioxidant properties were observed in the extracts. Cytotoxicity data demonstrated that all extracts showed high cytotoxic effects on HeLa cell line when compared to the NRK-52E cell line (p < 0.05).
Conclusion: These results suggest that VAC fruits (Monk’s pepper fruits) from Aegean sea coasts have a potential for use in the preparation of phytopharmaceutical products.
