Phytochemical contents and antioxidant activities of fern (Asplenium ceterach L.) distributed in different altitudes (22 stations) were compared and the relationships between altitude and plant chemical contents were studied. The highest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity was found in 22nd station (IC50 = 47.91 mu g/ml) and the highest total phenolic content was found in 9th station (110.62 mu gGAE/ml) whereas the maximum total flavonoid content was found in 20th station (232.67 mu gCE/ml). High performance liquid chromatography (HPLC) analysis indicates that the maximum pterosin b (0.235 mu g/ml), catechin (2.756 mu g/ml) and quercetin (0.207 mu g/ml) values were found in 21th station whereas the maximum chlorogenic acid (17.718 mu g/ml) was obtained in 9th and caffeic acid (6,598 mu g/ml) in 13th stations. It was observed that altitude is not potent alone, but it can be a factor in the occurrence of other ecological factors like soil properties, water, humidity, light and temperature.
