Abstract

MONTENEGRO, G; SALAS, F; PENA, RC  and  PIZARRO, R. Antibacterial and antifungic activity of the unifloral honeys of Quillaja saponaria, an endemic Chilean species. Phyton (B. Aires) [online]. 2009, vol.78, n.2, pp.141-146. ISSN 1851-5657.

The detection of phenolics, flavonoids and related compounds by HPLC in extracts of unifloral honey of Quillay (Quillaja saponaria) showed phenolic compounds such as caffeic, coumaric and salicylic acids, the flavanone naringenin and the flavonol kaempferol. These extracts showed antibacterial activity against Pseudomonas aureginosa, Escherichia coli, Staphylococcus typhi, S. aureus, Streptococcus pneumoniae type β, and Vibrio cholerae, and antifungal activity against Candida albicans. Additionally, some aroma and decomposition compounds were identified in the ethanol extract.

Keywords : Honey; MIC; Quillaja saponaria; Manuka; Flavonols; Flavanone; Phenolic compounds.
