The prevalence of patients infected with Methicillin resistant Staphylococcus aureus present different problems of nosocomial infections diseases in addition to multidrug resistance. This work aim to evaluate the antibacterial effect of four polyphenolic extracts from honey against Methicillin resistant Staphylococcus aureus. An extraction of polyphenol was carried out from different honey samples collected from different regions of the Algerian territory. First, the physicochemical, microbiological quality and pollen analysis was studied. Then, the evaluation of the antibacterial effect was performed by the determination of inhibition diameter and the minimal inhibitory concentration. The results clearly show the sensitivity of Methicillin Resistant Staphylococcus aureus against the polyphenolic extracts. The four samples presented an inhibitory effect and the polyphenolic extract of Jijel has the highest inhibitory effect among all extracts. This activity depend not only with the ...

We obtained honey from the blooming flowers of tea plants (Camellia sinensis L.) pollinated by honeybees (Apis mellifera L.). Functional amino acids, theanine, which is a unique ingredient to tea, was determined using reversed-phase chromatography. We also determined the main ingredients: caffeine and catechins. The obtained honey contained theanine, which shows that it was derived from tea flowers. The theanine concentration of the nectar of the tea flowers exceeded that of the honey. Caffeine was detected (but no catechins) in both the honey and the nectar of the tea flowers. Our results refute the previously held view that tea nectar is toxic to honeybees. Our new finding reveals that it is possible to obtain honey from the nectar of tea flowers. The obtained honey and the nectar of tea flowers contained a very rare amino acid, theanine, indicating that the honey was derived from tea flowers. Furthermore, the nectar of tea flower contained the best caffeine concentration that act...
