Abstract:
Fruit peels contain many useful substances which can be used as antioxidant, antimicrobials, and antivirus, etc. In this work, Punica granatum peels were cleaned, extracted with water and freeze dried into powder. The crude extracts were characterized using FTIR. The spectra represented the peaks at 3,271 cm-1 (OH stretching), 1,610 cm-1 (N-C=O stretching of amine groups) and 1,375 cm-1 (C=O stretching of ketone or aldehyde) of polyphenol. Antibacterial activities of water crude extracts were also evaluated by agar diffusion method. It was found that Staphylococcus aureus ATCC 25923, Staphylococcus aureus (MRSA) DMST 20654, Staphylococcus epidermidis ATCC 12228 and Acinetobacter lwoffii ATCC 15309 were inhibited. Crude extracts from Punica granatum peels showed high efficiency to be used as natural antibacterial agent with low cost. For application, polyvinyl alcohol and chitosan solution (20:1 in volume) were mixed with crude extracts from Punica granatum peels and formed into nanofiber using electrospinning technique. SEM micrograph showed structure of nanofiber with some beads. Polyvinyl alcohol and chitosan naofiber trends to be a suitable matrix for releasing of Punica granatum peel extracts and applied as wound dressing.
