Plants of the genus Hypericum, family Hypericaceae, are traditional plant species for various peoples used in conventional medicine. The expansion of the scope of their use is related to their phytochemical profile, determining a large part of their biofunctional properties. The study aimed to determine the phytochemical composition of the species Hypericum heterophyllum Vent. from Turkey, with potential opportunities for its application. Essential oil (0.13%), proteins (9.44%), cellulose (16.69%), total phenolics (252.66 mg GAE/g), and total flavonoids (7.70 mg QE/g) were found in the flowers. Extracts with methanol were obtained, and different methods were used in order to determine their antioxidant activity. The main essential oil compounds (over 3%) were: δ-terpineol (19.53%), spatulenol (10.66%), heptanal, dimethyl acetal (6.60%), δ-cadinene (4.77%), germacrene D (4.35%), γ-muurolene (3.93%), viridiflorene (3.22%), and β-linalool (3.12%).
