characterization of a potential nutraceutical ingredient pomegranate Punica Granatum l seed oil unsaponifiable fraction
Plant Foods for Human Nutrition, 2010Co-Authors: Augusta Caligiani, Francesca Bonzanini, Gerardo Palla, Martina Cirlini, Renato BruniAbstract:The chemical fingerprinting of the unsaponifiable fraction of different Punica Granatum seed oils was performed in order to evaluate their potential as a functional food ingredient. Qualitative and quantitative determinations of tocopherol, aliphatic alcohol (including policosanol), squalene, phytosterols and triterpene contents were performed by GC-MS. A high yield (3.1–4.2%) of unsaponifiable matter was obtained and consistent levels of squalene (up to 800 mg/kg) and policosanol (118–185 mg/kg) were noticed. β-sitosterol (up to 8069 mg/kg) and cycloartenol (5916–7766 mg/kg) were predominant in phytosterol and triterpene fractions, while β- and δ-tocopherol were the most abundant vitamin E forms. Some minor variations were noticed between samples. From the results obtained, it can be suggested that the seed oil of P. Granatum can be considered an interesting alimentary source of substances of nutraceutical value involved in the modulation of cholesterol metabolism.

antioxidant activity of vitis vinifera Punica Granatum citrus aurantium and opuntia ficus indica fruits cultivated in algeria
Heliyon, 2019Co-Authors: Nadia Zeghad, Abdelmalik Belkhiri, Ejaz Ahmed, Yvan Vander Heyden, Kristiaan DemeyerAbstract:Four edible fruits from Vitis vinifera, Punica Granatum, Citrus aurantium and Opuntia ficus indica from Algeria were analyzed in order to determine the total polyphenol, total flavonoid and flavonol contents using classical spectrophotometric methods. The antioxidant activity was established by three different single-electron-transfer-based assays (ABTS radical cation, FRAP, and DPPH assays) and one hydrogen-atom-transfer based assay (ORAC). Among the four fruits tested, the Vitis vinifera hydroalcoholic extract showed the highest antioxidant capacity with all methods. The results indicated that the antioxidant activity and the total phenolic content of the selected plants are significantly different (p < 0.001).
