Comparative Analysis of Phenolic and Flavonoid Content in Mango Varieties: Evaluating Antioxidant and Antimicrobial Activity

This study reports the antioxidant and antimicrobial attributes of different solvent extracts derived from selected mango varieties. The crude concentrated extracts (CCEs) obtained from Sindhri and Langra exhibited yields ranging from 6.12-23.89 g/100g and 6.64-24.86 g/100g per dry matter, respectively. These CCEs of Sindhri and Langra revealed a significant amount of total phenolic content over the range of 14.43-44.20 GAE (mg/100g) and 14.99-47.57 GAE (mg/100g), respectively. Similarly, the total flavonoid content in CCEs of Sindhri and Langra ranged from 9.85-30.54 CE (mg/100g) and 10.38-36.98 CE (mg/100g), respectively. The recovered CCEs of mango exhibited notable DPPH radical scavenging capacity with IC₅₀ values ranging from 6.78-18.53 µg/mL for Sindhri and 6.11-16.72 µg/mL for Langra. These extracts also exhibited strong ability inhibitory effects (37% to 79%) on the peroxidation process in the linoleic system. Aqueous ethanol (80%) exhibited the highest antimicrobial activity against a variety of pathogenic microorganisms, including Bacillus pumilus, Escherichia coli, Fusarium oxyesporum and Aspergillus niger, while distilled water CCEs displayed the lowest potential. The number of phenolic components detected exceeds those previously reported through HPLC analysis. The findings of this study strongly support the potential utilization of aerial parts of mango as valuable sources of antioxidant and antimicrobial agents.
