The aim of the study was to evaluate the antioxidant efficacy of extracts obtained from six Pinus species (P. pinea, P. brutia, P. radiata, P. halepensis, P. attenuata, P. nigra) growing in natural forests in Southern Greece. Specimens of fresh, dry needles and pine bark were extracted and fractionated with a variety of organic solvents and the efficient concentration and their radical scavenging activity was evaluated by the Co(II)/EDTA induced luminol plateau chemiluminescence assay.
