Comparative Analysis of Polyphenolic and Flavonoid Content, Antimicrobial and Antioxidant Activities of Moringa Olifeira Varieties from Mali and Algeria

Abstract

This study presents a thorough examination of the nutritional, medicinal, and industrial benefits of Moringa oleifera, specifically focusing on the total phenolic content (TPC) and total flavonoid content (TFC) in diverse extracts from leaves collected in Mali and Algeria. Utilizing ethanol extraction (EE-MO), the TPC and TFC were analyzed by UV spectroscopy, revealing a TPC range of 1 to 2.35 mg/g, with the highest value observed in leaves from Algeria (LA-MO). Total flavonoids varied from 0.72 to 1.9 mg/g, and Mali's powder and leaves (PM-MO and LM-MO) exhibited significantly higher TF results. The study establishes a linear relationship between TPC, TFC, and antioxidant activity, demonstrating the impact of agroclimatic conditions. Ethanol extracts from Moringa oleifera exhibited potent antibacterial activity, with Mali's leaves (LM-MO) demonstrating superior inhibition against specific bacteria. This research highlights geographical variations in Moringa oleifera properties and underscores its potential as a source of natural antioxidants for diverse industries, providing valuable insights for nutrition, medicine, and antimicrobial applications.
