Yu M, Gouvinhas I, Chen J, Zhu Y, Deng J, Xiang Z, Oliveira P, Xia C, Barros A. Unlocking the therapeutic treasure of pomegranate leaf: A comprehensive review on phytochemical compounds, health benefits, and future prospects. Food Chem X 2024; 23:101587. [PMID: 39036478 PMCID: PMC11260341 DOI: 10.1016/j.fochx.2024.101587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 06/20/2024] [Accepted: 06/21/2024] [Indexed: 07/23/2024] Open
Abstract
The exploration of sustainable and valuable by-products from industrial and agricultural processes is increasingly recognized for its economic, environmental and health advantages. This review examines the phytochemical constituents, biological properties, current applications and future directions of pomegranate (Punica granatum L.) leaf (PGL). PGL exhibits broad biological activities, aiding in managing health conditions like chronic diseases, cancer, diabetes, obesity, and neurological disorders. Anti-cancer and anti-diabetic effects are demonstrated in vitro and in vivo using animal models. Anti-inflammatory and neuroprotective properties are also observed in cell cultures and animal studies. Its anti-microbial properties show efficacy against pathogens. However, variability in phytochemical composition due to different extraction methods and environmental conditions poses challenges for standardization. The review underscores the urgent need for comprehensive human clinical trials to confirm PGL's therapeutic benefits and safety, calling for future research to fully harness PGL's potential as a sustainable and bioactive compound in various industrial applications.

Punicalagin Content and Antifungal Activity of Different Pomegranate (Punica ganatum L.) Genotypes. HORTICULTURAE 2019.

Abstract
This study investigated the antifungal activity of a number of pomegranate genotypes. Since the main compound of pomegranate extract is punicalagin, an important substance involved in antifungal and antimicrobial activity, we analyzed the contents of punicalagin (α and β) in 21 different pomegranate genotypes. Ellagic acid content, total phenolic content, acidity and pH were also determined. This work allowed us to determine which genotypes of pomegranate can be used to obtain extracts with the highest content of punicalagin, with the goal of developing a green alternative to synthetic pesticides. To improve the extraction system from pomegranate peel fruits, several different solvents were tested. All the pomegranate genotypes tested showed antifungal activity; some genotypes were able to almost completely inhibit the fungus, while others had very low inhibitory activity. Research results also showed that the use of water as a solvent for extraction is very effective, especially when it is combined with ethanol. This is very important for the practical use of the extracts since water is economical and environmentally friendly. The research showed that among the genotypes there is also great variability regarding the chemical parameters. Genotypes with a high phenolic and punicalagin content were significantly correlated with antifungal activity. All the other chemical parameters (pH, titratable acidity and ellagic acid content) were not correlated with antifungal activity. The results obtained indicate that the fruits of some pomegranate genotypes could be used to obtain extracts very rich in punicalagins and that these substances could be used as an alternative to synthetic products to control plant disease and improve the quality of the plant products, avoiding the impact of synthetic chemicals on the environment.

Abstract
The objective of the present study was to identify the metabolome pattern and study the biological efficacy of Almond (Terminalia catappa L.) peels. In the present study, metabolite profiling was carried out using GC-QTOF-MS and LC-QTOF-MS techniques, from the potent extract showed highest antioxidant efficacy. Antioxidant efficacy of the various extracts derived by six different extraction methods was assessed by different assays viz. 2,2-diphenyl-1-picrylhydrazyl, superoxide, 2,2'-Azino-bis-(3-ethyl)benzothiazoline)-6-sulfonic acid diammonium salt radical cation inhibition assays and ferric reducing antioxidant power. The methanolic maceration extract showed significant antioxidant activity in all assays and richest source of flavonoid content. The results showed that the extraction method significantly altered the antioxidant activity. The correlation between the antioxidant activities and total flavonoid content were ranging between 0.939 to 0.628. Methanolic maceration extraction method proved to be the best extraction method for the extraction of antioxidant. During the metabolite profiling employed by GC-QTOF-MS and LC-QTOF-MS and total 24 and 53 compounds belongs to different groups were detected and identified, will help to uncover the relation with potent antioxidant activity.
