Exploration of antioxidant and antimicrobial potential of prunus dulcis and arachis hypogaea shells extracts
Summary
Researchers explored the antioxidant and antimicrobial properties of almond and peanut shell extracts, finding that these agricultural waste products contain bioactive compounds with potential antibacterial, antifungal, and anti-inflammatory activities.
Almond (Prunus dulcis) and Peanut (Arachis hypogaea) both are the edible dry fruits, belong to families "Rosaceae" and "Fabaceae" respectively. There are number of studies have reported the biological activities of fruit but a very little data is available on shells. Shells extracts possess antiviral, antibacterial, anti-inflammatory, antifungal, and anticancer activities due to the presence of bioactive compounds, such as alkaloids, flavonoids, and polyphenolic compound. In the present study, green extraction technique was performed. The green extraction technique has many benefits over traditional extraction technique such as use of alternative solvents, reduction of energy consumption and unit operation and by-products in it. Firstly, shells were collected and crushed then their extracts were prepared through green extraction technique. The shells extract of Almond and Peanut were screened to investigate antioxidant, and antimicrobial potential. Antimicrobial activity was measured through well diffusion method while DPPH scavenging assay was performed to determine antioxidant potential. In our study, the antimicrobial activity of Almond shells extract was maximum against Staphylococcus aureus with zone of inhibition 19mm ±0.20 and minimum against the Salmonella enterica with zone of inhibition 7mm ±0.85.
