Title : Pomegranate peel (Punica granatum L.) phytochemistry, quantification, identification of phenolic compounds and antioxidant activity
Abstract:
Pomegranate (Punica granatum L.) a popular fruit known for its rich nutritional value and diverse bioactive compounds.Discarded as waste derived from the processing of Punica granatum L., peel potential as a rich source of bioactive compounds with diverse pharmacological effects. This study focused to valorize the pomegranate peels. The phytochemical composition of the methanolic extract of Punica granatum L. peel from three varieties of Algerian pomegranates. containing total polyphenols (Tp), total flavonoids (Tf), total tanins (Tt) as well as qualitative analyzes of phenolic compounds Individual high- performance liquid chromatography (Hplc) studies were evaluated. The results are expressed as mean ± Sd and showed a high content of total polyphenols and tannins for peel extracts. Total polyphenols, flavonoids, alkaloids, as well as anthocyanins were detected. Pomegranate extracts also showed significantly high phenolic (124.6 ± 0.409 to 757 ± 0.3472 mg Eag/g extract and to antioxidant capacities some differences existed between these cultivars (73,15 % to 92,27 %).The high antioxidant activities may be due to the high content of phenolics and flavonoids in pomegranate extracts. Six phenolic compounds identified in the cultivars analyzed were gallic acids, cathechin, quercein, berberine, resorcinol and rutin. Following all these properties of Algerian cultivars, studies can be further extended to possibly exploit them through their application in the preservation of food products as well as their use as food supplements and nutraceutic.
Keywords: Pomegranate Extract, phytochemicals, total phenolics, antioxidant activity, Hplc.
Audience Takeaway:
- The pomegranate is a fruit that is widely consumed in Mediterranean countries. Each year, several quantities of peels are released back into nature. Using the peels in herbal medicine or as a preservative, this will be very beneficial for the protection of health and the environment.
- The public through this study will know the beneficial effects of pomegranate peels, especially in terms of antioxidants.
- Yes, obviously, especially for pomegranate-producing countries.
- Yes, it will be hoped that this study will help provide new information and resolve the design problem.
