Introduction: Natural honey has been valued in traditional medicine having demonstrated many antioxidant properties. The aim of this study was to compare the antioxidant activities of 12 types of honey from Thailand and manuka honey from New Zealand. Methods: Antioxidant contents of phenolic content ferric reducing antioxidant power (FRAP) ascorbic acid content 2 2-diphenyl-1- picrylhydrazyl (DPPH) and Trolox Equivalent Antioxidant Capacity (TEAC) were determined in Thai and manuka honey samples. Results: All of the 12 types of Thai (n54) and manuka (n3) honey varied in range for phenolic content (210-1 519 563-785 mg GAE/kg) FRAP value (600-9 183 3 866-4 933 M Fe(II)/ kg) ascorbic acid content (103-386 913-1 212 mg/kg) DPPH radical scavenging activity (25-528 259-310 mg Trolox/kg) and TEAC content (96-636 328-421 mg Trolox/kg). Mangosteen honey had the highest content of phenolics (1 49520 mg GAE/kg) FRAP value (9 083100 M Fe(II)/kg) DPPH radical scavenging activity (5226 mg Trolox/kg) and TEAC content (6323 mgTrolox/kg). Conclusion: Antioxidant activities in mangosteen and rambutan honey presented significantly higher values than manuka honey in terms of phenolic content DPPH and TEAC. Manuka honey contained the highest vitamin C content (1 19418 mg/ kg). However the values for antioxidant properties were dependent on source of honey. Some honeys from Thailand were found to be a better source of antioxidant properties compared to manuka honey.

Abstract

Introduction: Natural honey has been valued in traditional medicine having demonstrated many antioxidant properties. The aim of this study was to compare the antioxidant activities of 12 types of honey from Thailand and manuka honey from New Zealand. Methods: Antioxidant contents of phenolic content ferric reducing antioxidant power (FRAP) ascorbic acid content 2 2-diphenyl-1- picrylhydrazyl (DPPH) and Trolox Equivalent Antioxidant Capacity (TEAC) were determined in Thai and manuka honey samples. Results: All of the 12 types of Thai (n54) and manuka (n3) honey varied in range for phenolic content (210-1 519 563-785 mg GAE/kg) FRAP value (600-9 183 3 866-4 933 M Fe(II)/ kg) ascorbic acid content (103-386 913-1 212 mg/kg) DPPH radical scavenging activity (25-528 259-310 mg Trolox/kg) and TEAC content (96-636 328-421 mg Trolox/kg).

Manuka honey contained the highest vitamin C content (1 19418 mg/ kg). However the values for antioxidant properties were dependent on source of honey. Some honeys from Thailand were found to be a better source of antioxidant properties compared to manuka honey.
