Tonsillitis, antibiotic, killer effect, pomegranate peels.


The purpose of this study is to know the effect of alcohol extracts of pomegranate fruits on two types of bacteria causing tonsillitis (Staphylococcus aureus&Streptococcus pyogenes) and compare their effect with the effect of commercial antibiotics. The extracts were obtained using three types of organic solvents (chloroform, hexane and methanol). Four concentrations were tested of each extract (25% -50% -75% -100%). Staphylococcus aureus was shown to be resistant to six tested antibiotics, particularly methyciline, indicating that this isolate was MRSA. Streptococcus pyogenes were sensitive to all antibiotics used in this study. The results showed the inhibitory efficacy of the extracts. (Chloroform, methanol) has a high inhibitory effect against the tested bacteria, which outweighs the effect of antibiotics especially against MRSA, which the WHO recommends to find new antibiotics for these bacteria, while the results did not show any effect of the hexane extract on These bacteria. The study also included the detection of active groups found in pomegranate husks.
