Identifying phenols in ornamental trees may provide sources of natural compounds that have applications in the agricultural and pharmaceutical industries. In this study, we profiled phenolic acids in the bark of Quercus sp. using HPLC-DAD. Q. robur showed high ellagic acid (in Q. robur). Q. macrocarpa had high caffeic acid. All species showed antibacterial and antifungal activities. P. aeruginosa was the most sensitive species for bark extracts. The antifungal activities were high against A. flavus. The study revealed new natural sources of phenolic acids that have antimicrobial activities with agricultural and pharmaceutical applications.
