Abstract

In this study, the chemical composition, physico-chemical properties and antioxidant activities of leatherwood honey from different locations with different climate across Tasmania were compared. Concentrations of 14 volatiles in the GC-MS profiles, 9 volatiles in the GC-FID profiles and 29 phenolic compounds in the HPLC-DAD/MS profiles along with pH, electrical conductivity, colour, hydrogen peroxide accumulation and antioxidant activity differed significantly between South and North samples. Correlations were found between beehive elevation and four unknown compounds U226 (R = 0.64), U169 (R = 0.68), U28 (R = 0.91) and U170 (R = 0.57). Annual rainfall was correlated with an unknown compound with a mass to charge ratio of m/z 181 (R = 0.40) and annual solar exposure was correlated with methyl syringate (R = 0.42), ellagic acid (R = 0.44) and two unknown compounds with mass to charge ratios of m/z 315 (R = 0.53) and m/z 181 (R = 0.67).

摘要

在本研究中，对塔斯马尼亚不同气候条件下不同地点的瑞香蜂蜜的化学成分、理化性质及抗氧化活性进行了比较。气相色谱 - 质谱（GC - MS）图谱中的14种挥发性成分、气相色谱 - 氢火焰离子化检测器（GC - FID）图谱中的9种挥发性成分以及高效液相色谱 - 二极管阵列检测器/质谱（HPLC - DAD/MS）图谱中的29种酚类化合物，连同pH值、电导率、颜色、过氧化氢积累量及抗氧化活性在南北样本间存在显著差异。发现蜂巢海拔与四种未知化合物U226（R = 0.64）、U169（R = 0.68）、U28（R = 0.91）和U170（R = 0.57）之间存在相关性。年降雨量与质荷比为m/z 181的一种未知化合物相关（R = 0.40），年日照量与丁香酸甲酯（R = 0.42）、鞣花酸（R = 0.44）以及质荷比为m/z 315（R = 0.53）和m/z 181（R = 0.67）的两种未知化合物相关。
