| Özet |
| Watermelon (Citrullus lanatus) flesh and seeds were dried and pulverized, and their extracts were diffused to sterilediscs for the evaluation of anti-microbial activity. The disc-diffusion technique was used to assess anti-bacterial activityagainst Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Pasteurella multocida, Yersinia enterocolitica, Serratiamarcescens, Klebsiella pneumoniae, Xanthomonas campestris, Staphylococcus aureus. Anti-fungal activity against the yeastsCandida albicans and Rhodotorula glutinis was also examined. Standard anti-biotics were also tested as controls.Watermelon flesh and seed extracts were found to be effective against gram-positive and gram-negative bacteria andyeasts. The extracts were also screened for anti-oxidant activity using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) freeradical-scavenging assay, total reducing ability using the Fe3+–Fe2+ transformation method and ferrous ion (Fe2+)-chelating activity. Butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), ethylenediaminetetraacetic acidand α-tocopherol were used as reference anti-oxidant radical scavenger compounds.The most potent anti-bacterial activity was demonstrated by watermelon–ethanol extract (inhibition zone 30 mm)against K. pneumoniae, and the most potent anti-fungal activity was demonstrated by watermelon–acetone extract(inhibition zone 26 mm) against R. glutinis. Watermelon–ethanol and watermelon seed–ethanol extracts both demonstratedmarked anti-oxidant activity.These results highlight that watermelon fruit and seed extracts have potential for the development of efficient, safeand cost-effective natural anti-oxidant compounds for application in the functional food industries. |
