Pomegranate fruit represents a rich source of bioactive components. These phytochemicals accumulate in different parts of the fruits, such as the exocarp, mesocarp, seeds and arils. Wild type species have been suggested to contain high amounts of potential bioactive compounds. Therefore a field campaign in eight different areas of Azerbaijan has been performed to collect pomegranate samples. In this work, the physical properties and the antioxidant capacities of peels, juice, flowers and leaves of the each different pomegranate accessions of eight wild pomegranate accessions grown under different conditions in different regions of Azerbaijan are reported, together with the identification and quantification of the phenolic compounds and the anthocyanin composition present in different parts of one pomegranate accessions. The study of bioactive components in P.g.1 showed that cyanidin-3,5-diglucoside (34.65%) was the predominant anthocyanin pigment of juice and -epicatechin was the most abundant polyphenol (67.23 mg/kg) in pomegranate exocarp. The results of this study will contribute to the assessment of wild pomegranate biodiversity and allow to detect samples with high quality characteristics of fruits for potential commercial production of medicinal and cosmetic products, food additives from this plant.
