The aim of this study was to investigate the secondary metabolites related to Pistacia atlantica Desf as well as their biological activities. Results show that using ethanol as a solvent exhibited the highest content of total phenolics and flavonoids (68.23 mg GAE g of DW and 44 mg RE g of DW), followed by aqueous one (20.07 mg GAE g of DW and 15 mg RE g of DW). Good correlation (Data not shown) was obtained between the DPPH radical-scavenging activities and total phenolics contents. Many similarities were observed between the results of the DPPH (IC = 32 and 200 μg mL) and ABTS (IC = 42 and 300 μg mL) assays. All tested extracts contained phenolic compounds exhibited an antimicrobial effect against Gram-positive and Gram-negative bacteria. Further, researches for identification and purification of phenolic compounds are required.

Background: A growing body of research is dedicated to developing new therapeutic agents for wound healing with fewer adverse effects. One of the proceedings being taken today in wound healing research is to identify promising biological materials that not only heal wounds but also vanish scarring. The effectiveness of nanofibers like polyvinyl alcohol (PVA), in improving wound healing can be related to their unique properties.

Article Synopsis
  • This study explored how Bene hull methanolic extract (BHME) can act as a natural antioxidant in reducing lipid oxidation in vegetable oils, comparing its effectiveness to synthetic antioxidants like BHT.
  • The research measured the antioxidant activity of BHME at different concentrations and storage times, using statistical tools like ANOVA and Support Vector Machine (SVM) models to analyze the results.
  • Findings showed BHME has significant antioxidant potential, especially in bulk oils, with effective comparisons to synthetic options, alluding to its promise for enhancing the shelf life of lipid-based food products.
