Abstract EN
The phenolic contents of 6 Libyan honey varieties of different floral sources were determined.
Honey samples included the 5 mono-floral honeys, Ziziphus louts, Citrus medica, Thymus capitatus, Amygdalus communis and Commiphor myrrha, while the multi-floral honey was Rabia (spring) honey.
The analysis of phenolic compounds was performed using High Pressure Liquid Chromatography.
Twenty three phenolic components in the different honeys were determined.
The highest number of phenolic components were found in the darker honeys, Thymus and Commiphor followed by Citrus, Rabia and Ziziphus, respectively.
The least number of phenolic components were detected in Amygdalus (only 4).
p- Hydroxybenzoic acid was found in all studied honey varieties, while rutin was not detected in any of honey samples analyzed.
Gallic acid and chrysin were found only in Thymus honey, Caffeic acid, salicylic acid and pinostrobin were only in Commiphor honey, while catechin, daidazein and pyro gallic were detected only in Citrus honey.
The phenolic contents can be used as a marker for the studied honey varieties.
The antimicrobial effect of on Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, Enterococcus faecalis, Pseudomonas aeuroginosa, Escherichia coli, Bacteriods spp., Sarcina spp.
and Candida albicans was studied.
All honey samples inhibited the growth of Escherichia coli with different degrees, where P<0.001.
Among all bacteria, Bacteroids spp.
and Klebsiella pneumoniae were the most resistant against most honey samples.
