“…In addition, no significant variation was observed in lipids among all the tested samples. These findings are quite close to those described by [ 25 , 50 , 51 ] for Siwi, Ajwa, and Sukkari dates. The variances in the chemical composition of the investigated dates could be ascribed to differences in cultivar, soil fertility, growing environment, ripening stage, and harvest/postharvest practices.…”

“…The reducing sugars represented most of the sugars found in the studied date varieties, where the percentage of reducing sugars ranged between 71.5 ± 1.25 and 75.6 ± 1.05, and the Sukkari date recorded the highest percentage, while the lowest percentage was in the Ajwa variety. Our findings are similar to those described by Perveen and Bokahri [38] and greater than those indicated by Al-Tamim, Aldhafiri, and Siddeeg et al for the Sukkari date [25,50,51]. The results are also consistent with those reported by Selim et al [49] and higher than those reported by Ramadan et al for the Siwi date variety [48].…”

Date palm (Phoenix dactylifera L.) fruits contain high concentrations of phenolic compounds, particularly flavonoids and other micronutrients, which impact human health due to their potent antioxidant, anti-inflammatory, and anticancer characteristics. In the present study, the effect of ethyl acetate, hydroethanol, hydromethanol, and aqueous extract from three date palm varieties (i.e., Ajwa, Siwi, and Sukkari) on phytochemical profiles and antioxidant and anticancer activities was investigated. Fruit extracts were screened for their antioxidant activity using the DPPH· method. Phenolic constituents were quantified and identified using HPLC-DAD. Extracts (ethyl acetate, hydroethanol, and hydromethanol) were assessed for cytotoxicity on nine human cancer cell lines, i.e., MG-63, HCT116, MCF7, MDA-MB-231, HEPG2, HUH7, A549, H460, and HFB4, using the sulphorhodamine-B (SRB) assay. Results showed that the ethyl acetate extract of the Sukkari fruits has the greatest antioxidant potential with an IC50 value of 132.4 ± 0.3 μg·mL−1, while the aqueous extract of Ajwa date fruits exhibited the lowest antioxidant effect with an IC50 value of 867.1 ± 0.3 μg·mL−1. The extracts exhibited potent to moderate anticancer activities against the investigated cancer cell line in a source-dependent manner. Methanol extract of Siwi fruits exhibited the most potent anticancer activity (IC50 = 99 ± 1.6 µg·mL−1), followed by the same extract of Sukkari fruits with an IC50 value of 119 ± 3.5 µg·mL−1 against the cell line of human breast cancer (MDA-MB-231). Additionally, principal component analysis (PCA) was investigated to determine the relationship among the investigated traits and treatments. Our findings reveal that date palm fruit-derived extracts are excellent sources of biologically active constituents and substantiate their potential use in new anticancer strategies from natural resources.

The present study was conducted to evaluate the phytochemical profile of green grasses including barley and wheat. Green grasses were procured from Ayub Agricultural Research Institute, Faisalabad, Pakistan. All the phytochemical parameters were determined through standard methods with slight modifications. The explored parameters include proximate analysis, mineral profile, vitamin profile, and especially antioxidant profile (total phenolic contents (TPCs), free radical scavenging activity, flavonoids, and phenolic acids). The results portrayed that there was a significant difference between the proximate parameters, vitamin, and minerals profile of both barley and wheatgreen grasses. The antioxidant profileantioxidant activity (283.5%) and free radical scavenging activity (99.29%)of barley grass was much higher than wheatgrass. The TPCs (203.52 µmol of GAE/g) and flavonoids (161.12 μmol/L) were much higher in wheatgrass as compared to barley grass. Barley grass showed maximum contents of phenolic acids including benzoic acid (73.84 µg/g), caffeic acid (86.61 µg/g), gallic acid (6.33 µg/g), syringic acid (170.46 µg/g), p-hydroxybenzoic acid (42.52 µg/g), and Ferulic acid (1560.3 µg/g). Conclusively, barley grass showed higher antioxidant potential.

Antioxidant Content Determination in Ripe Date Fruits (Phoenix dactylifera L.): a Scoping Review

et al. 2021

View full text Add to dashboard Cite

Ripe date fruits are a rich source of antioxidants. The current scoping review was conducted to identify various characteristics of studies that were carried out to determine antioxidant content in ripe date fruits. The framework established by Arksey and O’Malley was adopted to conduct this scoping review. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) was used as a guide during the review process. Relevant studies published in March 2019 or any time before were retrieved from three databases. Study selection was performed based on specific inclusion criteria. The extracted data from selected studies were organized in a charting table, and then analyzed using descriptive statistics. A sum of thirty-one articles were selected and included in the present scoping review. Various characteristics of the selected studies, collected ripe date fruit samples, and extraction solvents, as well as information about determining antioxidant content and the used analytical methods, citation references for procedures, measurement units, and data presentation methods, have been identified and discussed carefully. High inconsistency and variability were observed among the selected studies. The research gaps and future recommendations to promote higher research design consistency and improve research quality in this area of research have been described.
