Abstract

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 andÂ the antioxidant capacities of peels, juice, flowers and leaves of the each different pomegranate accessions ofÂ 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.

Highlights

Worldwide, active work is underway to identify new sources of bio-antioxidants
The purposes of this study were: a) to study the physical properties of the eight wild pomegranate accessions collected in different regions of Azerbaijan; b) to identify and quantify the phenolic compounds and the anthocyanin composition present in different parts of one pomegranate accessions; c) to investigate the antioxidant capacities of different tissues of the eight pomegranate accessions
The average fruit weight of pomegranate accessions ranged from 37.33 g (P.g.4) to 99.33 g (P.g.8)
