ANTIBACTERIAL POTENTIAL OF GREEN SILVER NANOPARTICLES SYNTHESIZED FROM LEAVES AND BARK EXTRACT OF SIMAROUBA GLAUCA

Abstract

Green synthesis of silver nanoparticles using the leaves and bark extract of Simarouba glauca DC is reported in the present investigation. Synthesized nanoparticles are characterized under UV-Vis spectrophotometer at the range 200-800 nm. The peak showed at 444 to 450 nm for leaves and 462 nm for the bark sample. FESEM studies revealed the nanoparticles synthesized from leaves and bark extract are spherical in shape and size ranging between 30-50 nm and 50-60 nm respectively. These silver nanoparticles showed inhibitory activity against micro-organisms such as Staphylococcus aureus and Pseudomonas aeruginosa, and exhibits antibacterial potential. Thus these silver nanoparticles might be used in the drug delivery system in pharma and agricultural industries.
