A Survey of the Antibacterial Activity of Some New Zealand Honeys

摘要: To assess the variation in antibacterial activity of honey a survey was carried out on 345 samples unpasteurized obtained from commercial apiarists throughout New Zealand. Most honeys were considered to be monofloral, 26 different floral sources. The tested against Staphylococcus aureus an agar well diffusion assay, with reference phenol as standard. Antibacterial found range equivalent less than 2% (w/v) 58% phenol, median 13.6 and standard deviation 12.5. Neither age nor whether they had been processed by apiarist associated lower activity. However, difference between sources very highly significant. Kanuka (Kunzea ericoides (A. Rich.) J. Thompson. Family: Myrtaceae), manuka (Leptospermum scoparium R. et G. Forst. ling heather (Calluna vulgaris (L.) Hull. Ericaceae) kamahi (Weinmannia racemosa Linn. f. Cunoniaceae) shown likely give high When assayed catalase added remove hydrogen peroxide, most showed no detectable Only vipers bugloss (Echium vulgare L. Boraginaceae) this type significant proportion samples. many cases due entirely non-peroxide component.
