Photoprotective activity of C. siliqua extracts. (A) Photoprotective activity of carob extracts on ultraviolet B (UVB)-irradiated normal human fibroblasts; the highest noncytotoxic concentration was tested (200 μg/mL, Table S1); DMSO-treated, irradiated, and nonirradiated cells served as negative controls; bars represent mean values ± SD (n ≥ 3); error bars correspond to statistical difference between irradiated control and irradiated samples; ** p < 0.01 (Student’s t-test); control values were set to 100%. (B) Carob extracts’ UV absorbance scans at 200 μg/mL in comparison to phosphate-buffered saline (PBS).
