In Northeast part in Turkey, wild grown fruits are abundant and they are widely collected and consumed by rural peoples. In this study, the fruits of seven sea buckthorn genotypes from Northeast in Turkey were sampled and analyzed for their total phenolic content, vitamin C, total anthocyanins and antioxidant capacity. Total phenolic, vitamin C and total anthocyanin content varied from 213 to 262 mg GAE/100g FW; 28-85 mg/100 g and 3-21 mg/L among genotypes. Antioxidant capacity analyses (in DPPH and β-carotene method) showed that all samples had a high antioxidant (average 94.23% in β-Carotene and 31.23% in DPPH) capacity.
