hytochemicals properties and antimicrobial activities of Carica papaya andBalanites aegyptiaca’ seeds aqueous infusion and decoction extracts

Résumé

Carica papaya and Balanites aegyptiaca seeds extract have several uses, from food totraditional medicine. This study aims to determine their phytochemicals compound andappreciate their antimicrobial properties against clinical strains. Polyphenolic content wasdetermined with standard methods while DPPH radical scavenging activity is used toappreciate the antioxidant properties, using ascorbic acid as standard. Antimicrobial activitieswere performed according to the inhibition diameters, using agar diffusion method. Minimum inhibitoryconcentrations and Minimum fungicidal concentrations were established based on broth dilutionmethods. The extraction yield is ranged between 6.3 and 20.3%. The results shown polyphenoliccontent varying from 1256.13±21.09 to 2315.81±53.52 μg GAE/100 mL for Carica papaya andfrom 303.98±0.93 to 948.06±3.23 μg GAE/100 mL for Balanites aegyptiaca while theantioxidant activity is ranged between 31.76±2.35 and 58.47±4.24 μg AEAC/100 mL for Caricapapaya and from 29.80±0.32 to 78.44±2.81 μg AEAC/100 mL for Balanites aegyptiaca.Infusion’s extracts always have the highest values of polyphenols content and antioxidantactivity than decoction extracts, be it papaya or balanites seeds. Neitheir flavonoids contentnor antibacterial activity was found. The inhibition diameter varies from 14.5±0.5 to 40.5±0.5mm for papaya seeds extracts and from 16.5±0.5 to 21.0±0.5 mm for balanites seeds extractswithout a significative effect of mixture for both extracts. MICs vary from 11.71±0.1 to 75.0±0.0mg. mL-1 for Carica papaya seeds extracts with 11.72±0.2 to 37.30±0.2 mg. mL-1 and 18.74±0.1to 100±0.0 mg.mL-1 for Balanites aegyptiaca. Mixture extracts presented intermediaire values.Decoction extracts have lowest MICs values and infusion reveals itself to be the sweetableaqueous extraction techniques but the appropriate infusion time need to be highlight.
