Chemical composition and antimicrobial activity of Sidr honey

ABSTRACT

A comparison between two methods of extraction of Sidr honey was performed to elucidate the difference in chemical composition and antimicrobial activity. The results of the GC/MS studies of the n-hexane extracts by methods A [extraction without dilution] and B [extraction after dilution with water] for Sidr honey showed that method A contains all terpenoids and method B contains higher significant concentration of fatty acids. Some compounds were identified for the first time in Sidr honey. Piperitone, calamanene -1S-trans, 4-methoxy -butanoic acid, 2- pentanol -5- methoxy-2- methyl, Pyrido [3,2-d] pyrimidine - 4-ol, 2- ethyl- 5- tridecylpyrrolidine, quinoline -, 5,6,7,8-tetrahydro - 3-methyl and quinoline - 4,8-dimethyl. The antimicrobial activity varied according to the type of pathogen. However the method A showed the highest antibacterial activity, the method B had the highest antifungal activity
