We evaluated the antioxidant, antibacterial, and
anti-inflammatory activities of honey made from different floral sources,
including the medicinal herb Bidens pilosa, fruit trees, Dimocarpus longan,
Litchi chinensis, and Citrus maxima, the Taiwanese endemic plant Aglaia
formosana, and a multifloral forest.
The total phenolic and flavonoid contents of the honey made
from B. pilosa were significantly higher than those of the other honeys. The
honey from B. pilosa also had significantly greater scavenging activities for
1,1-diphenyl-2-picrylhydrazyl (DPPH·) and hydroxyl radical, and substantially
more reducing power. In addition, the honey from B. pilosa showed greater
antibacterial activity against Gram-positive and Gram-negative bacteria.
However, B. pilosa honey showed little inhibitory activity against IL-8
secretion, whereas the other honeys did.
These findings suggest that the levels of antioxidant and
antibacterial activities are attributable to the total phenolic and flavonoid
contents of honeys, while the IL-8 inhibition is attributable to components
other than phenols.
