摘要：

The phenolic acid and flavonoid contents of Malaysian Tualang, Gelam, and Borneo tropical honeys were compared to those of Manuka honey. Ferric reducing/antioxidant power assay (FRAP) and the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activities were also quantified. All honey extracts exhibited high phenolic contents (15.21 +/- 0.51- 42.23 +/- 0.64 mg/kg), flavonoid contents (11.52 +/- 0.27- 25.31 +/- 0.37 mg/kg), FRAP values (892.15 +/- 4.97- 363.38 +/- 10.57 mu M Fe[II]/kg), and high IC50 of DPPH radical-scavenging activities (5.24 +/- 0.40- 17.51 +/- 0.51 mg/mL). Total of 6 phenolic acids (gallic, syringic, benzoic, trans-cinnamic, p-coumaric, and caffeic acids) and 5 flavonoids (catechin, kaempferol, naringenin, luteolin, and apigenin) were identified. Among the Malaysian honey samples, Tualang honey had the highest contents of phenolics, and flavonoids, and DPPH radical-scavenging activities. We conclude that among Malaysian honey samples, Tualang honey is the richest in phenolic acids, and flavonoid compounds, which have strong free radical-scavenging activities.
