“…Antibacterial activities of the honey samples with 100 % concentration against P. auregenosa and E.coli strains are presented in Figure 2 and 3. The inhibition zones of honey samples varied from (26-31) mm by P. auregenosa to (18)(19)(20)(21)(22)(23)(24) mm by E. coli. The growth inhibition profiles of natural honeys are presented in Figure 4 and 5.…”

“…Phenolic compounds originating from plant nectar have been proposed as important factors for the no peroxide antibacterial activity of honey [60]. Several antibacterial phenolic compounds have been identified in honeys [61][62][63]. Davidson et al [64] have shown that individual phenolic compounds have growth inhibition on a wide range of Grampositive and Gram-negative bacteria.…”

“…Honey has been shown to efficiently inhibit bacterial growth in vitro and in vivo [19]. The antimicrobial properties attributed to honey have been related to both the physical properties of osmosis and the antibacterial properties of hydrogen peroxide levels and the presence of some phytochemicals, mainly phenolic compounds including phenolic acids and flavonoids [20,21]. Numerous in vitro methods are used to evaluate the antioxidant potential of natural products [22][23][24][25] for honey antioxidant capacity determination, DPPH radical scavenging assay is a highly accepted method [26][27][28][29].…”

Six Algerian honeys from different floral origins, were examined for potential antibacterial and antiradical activity. The Folin-Ciocalteu assay was used to measure total phenol content (TPC) and the 2,2-diphenyl-picrylhydrazyl (DPPH) assay was used to determine the scavenging activity of the honey samples. An agar well diffusion assay and spectrophotometric method were used to assess antibacterial activity against two Gram negative strains (Escherichia coli ATCC25922 and Pseudomonas aeruginosa ATCC 50071).Total phenolic content varied from 63.93 to 95.36 mg/100 g honey as gallic acid equivalent. The DPPH radical scavenging assay was found for an average (30.14 % ± 9.28). The honey samples were found to inhibit all of the tested bacteria. Correlation existed between phenolic content and antiradical activity. Thus Algerian honeys, being a rich source of natural antioxidants, may be used in the prevention of various free radicals related diseases.

“…Importantly, it constitutes more than 70 % w/w of the phenolic fraction of manuka honey and can be regarded as a floral marker for this honey type (Weston et al, 2000). Earlier work on New Zealand manuka honey by Wilkins et al (1993a) showed this compound to be present in methylated exfracts but it was not clear if it was naturally present or the results of methylation of the corresponding syringic acid.…”

“…Further, methyl syringate (116) constitutes approximately 70 % w/w of the phenolic fraction of manuka honey, another Leptospermum honey and is reported as a floral marker for this honey type (Weston et al, 2000). Methyl syringate (116), methyl 4-hydroxybenzoate, methyl vanillate, /rain5-/>-methylcourmarate and /ra«.y-methyl ferulate were constituents of a range of European floral types of honey (Joerg and Sontag, 1993).…”

SummaryThe antibacterial activity of honey has been known since the 19th century. Recently, the potent activity of honey against antibiotic-resistant bacteria has further increased the interest for application of honey, but incomplete knowledge of the antibacterial activity is a major obstacle for clinical applicability. The high sugar concentration, hydrogen peroxide, and the low pH are well-known antibacterial factors in honey and more recently, methylglyoxal and the antimicrobial peptide bee defensin-1 were identified as important antibacterial compounds in honey. The antibacterial activity of honey is highly complex due to the involvement of multiple compounds and due to the large variation in the concentrations of these compounds among honeys. The current review will elaborate on the antibacterial compounds in honey. We discuss the activity of the individual compounds, their contribution to the complex antibacterial activity of honey, a novel approach to identify additional honey antibacterial compounds, and the implications of the novel developments for standardization of honey for medical applications.
