“…The oxidative damage to neurons is closely related to the pathogenesis of AD [ 24 ]. In this article, the anti-oxidative activity of compounds 1 – 20 was evaluated by DPPH assay with Vitamin C (Vc) as the positive control [ 25 ]. The free radical scavenging ability was evaluated based on the UV absorbance change of the solution measured at 517 nm using a microplate reader [ 26 ].…”

Gx-50 is a bioactive compound for the treatment of Alzheimer’s disease (AD) found in Sichuan pepper (Zanthoxylum bungeanum). In order to find a stronger anti-AD lead compound, 20 gx-50 (1–20) analogs have been designed and synthesized, and their molecular structures were determined based on nuclear magnetic resonance (NMR) and mass spectrometry (MS) analysis, as well as comparison with literature data. Compounds 1–20 were evaluated for their anti-AD potential by using DPPH radical scavenging assay for considering their anti-oxidant activity, thioflavin T (ThT) fluorescence assay for considering the inhibitory or disaggregate potency of Aβ, and transgenic Drosophila model assay for evaluating their rescue effect on memory loss. Finally, compound 13 was determined as a promising anti-AD candidate.

“…The antioxidant activity of extracted mango kernel butter was determined spectrophotometrically (Ruiz‐Ciau et al, 2017). A methanolic solution of oil 750 μl of a particular concentration (0.02 mg/ml) was placed inside test tubes and a methanolic solution of DPPH (1.5 ml, 20 ppm) was added to each tube.…”

Mango is an important tropical fruit with worldwide consumption and acceptance; however, the production of a large volume of waste in the form of mango seed kernels after the processing of mango has been a menace to food processing industries.Extraction of mango seed kernel butter from mango seed kernel can be an effective solution for the valorization of these by-products. Among all the green techniques tested in the present studies, ultrasound-assisted extraction gave the highest yield of mango seed kernel butter (11%) at 25 C, 1:20 solid-liquid ratio, 30% amplitude after a treatment time of 10 min. Physicochemical, structural, and thermal profiles of the extracted mango seed kernel butter revealed a comparatively superior quality of fat obtained using the ultrasonication technique as compared to the conventional method. Peroxide value, acid value, and antioxidant activity of mango seed kernel butter obtained using ultrasonication were found to be 2.8 meq/kg, 3.81 mg KOH/g, and 30.7%, respectively. Mango seed kernel butter, being a natural antioxidant, can serve as a promising substitute to edible oils and as a functional food ingredient in bakery and confectionery. Practical applicationsValorization of mango seed kernels for the extraction of mango seed kernel butter offers a sustainable and economical solution for the effective management of byproducts generated after mango processing. The application of ultrasonication can prove to be an effective green technique for the extraction of mango seed kernel butter with a higher yield obtained with lesser time and solvent consumption than conventional techniques. The ultrasonically extracted mango seed kernel butter exhibited better physicochemical and structural attributes than the conventional method without causing any negative impact on the nutritional profile of the obtained fat. The extracted mango seed kernel butter can be utilized as a functional food ingredient in applications of bakery and confectionary industries.

“…This test is based on the reduction in the purple DPPH radical using an oxidizing antioxidant. The scavenging effects of vitamin C and caffeic acid corresponded to the quenching intensity of 1.1-diphenyl-2-picrylhydrazyl (DPPH), as carried out by [31,34]. A wavelength of 520 nm was set to measure the reduction in the purple DPPH radical.…”

This study was conducted to assess the bioactive value of Tamarix gallica honey samples collected from three countries. In total, 150 Tamarix gallica honey samples from Saudi Arabia (50), Libya (50), and Egypt (50) were collected and compared, based on the results of the melissopalynological analysis, their physicochemical attributes, antioxidant and antimicrobial activities, and biochemical properties, together with their total phenolic and total flavonoid contents. Depending on the geographical origin, we observed different levels of growth suppression for six resistant bacterial strains. The pathogenic microorganisms tested in this study were Staphylococcus aureus, Streptococcus mutans, Klebsiella pneumoniae, Escherichia coli, Proteus vulgaris, and Pseudomonas aeruginosa. There was a strong correlation between the polyphenol and flavonoid contents, as well as significant (p < 0.05) radical scavenging activities. The melissopalynological analysis and physicochemical properties complied with the recommendation of the Gulf and Egyptian Technical Regulations on honey, as well as the Codex Alimentarius of the World Health Organization and the European Union Normative related to honey quality. It was concluded that Tamarix gallica honey from the three countries has the capacity to suppress pathogenic bacterial growth and has significant radical scavenging activities. Moreover, these findings suggest that Tamarix gallica honey may be considered as an interesting source of antimicrobial compounds and antioxidants for therapeutical and nutraceutical industries or for food manufacturers.
