Phytochemical evaluation of Pteridium aquilinum in masal elevation gradient of Gilan province.
Invasive species are globally endangered for ecosystems, and ecologists are increasingly concerned about them. Pteridium aquilinum is one of the most invasive species widely distributed in the world. This study investigated the phytochemical of Pteridium aquilinum species in different altitude gradients. So, random sampling was performed from vegetation and soil in three altitudes (0-700, 700-1400 and 1400-2100 meters) with three replications for both growth and reproduction stages. In the growth stage, the composition of Linalool was the highest value (1.09) in the altitude of 0-700 m. During the reproductive stage, Sabinene and -α Thujene had the highest values in the altitude of 0-700 m with 0.15 and 0.13%, respectively. The amount of oil in the growth stage is more than the reproductive stage, so it can be concluded that the growth stage will have a significant effect on the amount of oil compounds.
