ABSTRACT: The physical
properties, total phenols, total flavonoid content and free radical scavenging
activities of honey samples from Malaysia were investigated. The physical
properties of Tualang, Gelam and Acacia
honey samples, in terms of pH, color, moisture, electrical conductivity
and total soluble solid were significantly
different (p = 0.000). Gelam
honey was reported to have the highest total phenols (606.17 mg GAE/kg honey)
and flavonoid content (183.43 mg RE/kg honey). Tualang honey was reported to
have the highest free radical scavenging activity with the IC50,
72.75 g/L compared to Gelam (77.41 g/L) and Acacia (90.83 g/L). There is no
significant difference has been revealed
among honey samples for radical scavenging activity (p = 0.827). Nevertheless, strong
correlation was obtained between pH, color, electrical conductivity and total
soluble solid with the scavenging activity of all honey samples with the
correlative coefficient, r = 0.979,
0.902, 0.917 and 0.957, respectively. The establishment of the statistical
correlation could be useful for honey related industry.
