Studies on the antioxidant properties of Tualang honey of Malaysia
Honey has been used since ancient times for its nutritional as well as curative properties. Tualang honey is collected from wild honey bees’ hives on Tualang trees found in the Malaysian rain forest. It has been used traditionally for the treatment of various diseases, where its therapeutic value has partly been related to its antioxidant properties. This study therefore assessed the colour intensity, total phenolic content, antioxidant activity and antiradical activity of gamma irradiated Tualang Honey. The colour intensity at ABS45O was 489.5 ± 1.7 mAU, total phenolic content was 251.7±7.9 mg gallic acid /Kg honey, total antioxidant activity by FRAP assay was 322.1±9.7 (μM Fe(II)) and the antiradical activity by DPPH assay was 41.30 ± 0.78 (% inhibition). The data confirms that the antioxidant properties of gamma irradiated Tualang honey are similar to other types of honeys reported in the literature.
