dc.description.abstractPortuguese monofloral honeys from carob tree, chestnut, bell heather, eucalyptus, incense, orange, and strawberry tree, were evaluated in vitro for antimicrobial, antioxidant, wound healing, and cell viability effect, compared to manuka honey 850+. Antimicrobial activity was determined against Gram+-and Gram- bacteria and yeast. Antioxidants, wound healing, and cell viability effects were studied in the Human Keratinocyte (HaCaT) cell line. Chestnut, bell heather, eucalyptus, manuka and strawberry tree honeys were most effective against S. aureus with a minimum inhibitory concentration (MIC) of 12.5%-25.0% (w/v), and greater ability to decrease reactive oxygen species (ROS) production (> 75%), than manuka honey (68%). Incense and orange honeys exhibited high wound healing rates, 89% and 86%, respectively, higher than manuka honey, 53%. Honeys showed cell viability > 76%. Bell heather and strawberry tree honeys exhibited the highest total phenolic content, 38 and 137 mg/100 g honey respectively, being more effective against the microorganisms tested and showing greater antioxidant activity. Opposite, incense, and orange honeys with lower phenolic amounts, 11 and 15 mg/100g honey, respectively, achieved higher wound healing ability. Flavonoid aglycones were the most abundant flavonoids in all honeys. This knowledge can be further explored in formulations that take the best out of each honey type composition and biological activity capacity.pt_PT
