Abstract
Antioxidant activities of honey and propolis
of stingless bee, Tetragonula iridipennis from Nagaland were
standardized. As honey components varies with climates and vegetations, samples
were collected twice in a year during winter and summer. Propolis was taken
from honey cells (cerumen) once in a year, as their hives were perennial
structure. Antioxidant activities were estimated in terms of total phenolic
contents, flavonoid contents, free radical (DPPH) scavenging activities and
ferric reducing antioxidant power (FRAP). Highest phenolic contents
(128.97±0.01mgGAE/Kg) were recorded in winter honey followed by summer honey
(117.32±0.03mgGAE/Kg). In contrast, flavonoid contents were found to be maximum
in propolis (75.83±0.002mgQE/Kg). DPPH radical scavenging activities were
measured in terms of IC50 values, where winter honey and propolis exhibited
significantly high antiradical activity when compared with standard ascorbic
acid. Highest FRAP values were recorded in winter honey, followed by propolis
and summer honey respectively. In fact, the results signified honey and
propolis of T. iridipennis as reliable sources of antioxidants with
adequate market potentialities.
