GREEN SYNTHESIS, ANTIMICROBIAL AND ANTICANCER ACTIVITIES OF AgNPs PREPARED FROM THE LEAF EXTRACT OF Eucalyptus camaldulensis

“…However, in comparison with our study, MIC values were lower; MIC=between 0.8 and 1 g mL -1 [41]. In another study, MICs of nanoparticles of Eucalyptus globulus leaf extract were 0.078 mg µL -1 for B. cereus and S. aureus, however it was 0.19 µg µl -1 and 0.39 µg µl -1 for P. aeruginosa and E. coli, respectively [42]. In summarized, the antimicrobial activity of silver nanoparticles incorporated with E. camaldulensis increased against all microbes used.…”

In-vitro anticancer activity against Caco-2 cell line of colloidal nano silver synthesized using aqueous extract of Eucalyptus Camaldulensis leaves

“…Nevertheless, Eucalyptus camaldulensis leaves contain a wide range of bioactive compounds including saponins, tannins, flavonoids, carbohydrate and proteins [ 28 ], which play important roles as reducing and capping agent during the formation of nanoparticles [ 29 , 30 ]. There are many articles published on the synthesis of AgNPs using different species of Eucalyptus such as Eucalyptus corymbia [ 31 ], Eucalyptus globules [ 32 ], Eucalyptus critriodora [ 33 ], and Eucalyptus tereticornis [ 34 ] etc… But, few studies have been reported in the using of aqueous extract of Eucalyptus camaldulensis leaves for synthesis silver nanoparticles [ 30 ].…”

In Vitro Evaluation of Antimicrobial and Antioxidant Activity of Carica Papaya L. Seeds Grown in the Republic of Yemen

“…Our results reinforce the ones previously reported by [30], which revealed a higher FRAP value in the pulp of sea buckthorn (Hippophae rhamnoides L.) than in seed. By contrast, papaya seed extracts were found to be a more potent source of antioxidants by ABTS method than tamarind (8.32 µmol TE/g), pineapple (3.78 µmol TE/g), murici (Byrsonima crassifolia) (15.73 µmol TE/g) and mangaba (10.84 µmol TE/g) as reported by [31,32,33].…”
