The genus Quercus with over 1,000 species, is extensively dispersed throughout the temperate woodlands of Northern Hemisphere and tropical climate zones. rich in phenolic acids, triterpenoids, plant-based polyphenolic compounds. It also has numerous biological effects, such as antibacterial, anti-inflammatory, liver-protective, gastroprotective, anticancer, antidiabetic, antioxidant activities. To investigate morphological phytochemical diversity Iranian oak (Quercus brantii Lindl.) populations from ten different geographic regions Iran were collected. Morphological, cytotoxic traits measured analyzed. Among traits, dry leaf weight (69.21%) had maximum coefficient variation. In addition, highest total phenol (100.17 mg GAE/g DW), flavonoid content (74.6 RE/g tannin (56.60 DW) found Sardasht population, minimum Piranshahr population. IC50 values ranged 5.52 to 18.65 µg/mL, lowest population most elevated Ilam Gallic acid, salicylic rutin, rosmarinic acid identified principal Cluster analysis based on data represented 3 main groups. Principal component revealed that first second components explained 38.52% 30.01% variance, respectively. Oak fruit extracts not at concentration 100 µM. Based results this study, best can be selected achieve yield, content, according needs pharmaceutical food industries.
