Phenolic Compounds as Unambiguous Chemical Markers for the Identification of Keystone Plant Species in the Bale Mountains, Ethiopia.

Despite the fact that the vegetation pattern and history of the Bale Mountains in Ethiopia were reconstructed using pollen, little is known about the former extent of species. The main objective of the present study is to identify unambiguous chemical proxies from plant-derived phenolic compounds to characterize and other keystone species. Mild alkaline CuO oxidation has been used to extract sixteen phenolic compounds.
