Abstract
Purpose
The purpose of this study is to analyze the flavonoid composition and organochlorine compounds (OCs) in honey samples from different floral sources on the Ryukyu Islands of Japan, and to determine their nutritional characteristics and the risk of intaking hazardous pollutants.
Design/methodology/approach
Honey samples were collected from various regions of the Ryukyu Islands. Thirty-one samples were analyzed for six flavonoid compounds by high-performance liquid chromatography, and OCs from 14 samples were analyzed by gas chromatography. The differences in flavonoid composition among the samples from different floral sources were determined.
Findings
Honey from Bidens pilosa L. var. radiata Sch. Bip. contained high concentrations of luteolin and apigenin. One sample with polychlorinated biphenyls and two with chlordane compounds were detected in one region; however, their concentrations were lower than those for food regulations.
Originality/value
Novel chemical characteristics in Ryukyu honey, including high amounts of luteolin and apigenin from B. pilosa, were discovered, whereas low OC contamination was observed.
目的分析日本琉球群岛不同花源蜂蜜中黄酮类化合物和有机氯化合物(OCs)的含量，确定其营养特性和摄入有害污染物的风险。设计/方法/方法从琉球群岛的不同地区收集蜂蜜样本。用高效液相色谱法分析了31个样品中的6种黄酮类化合物，用气相色谱法分析了14个样品中的OCs。测定了不同花源样品中黄酮类成分的差异。从Bidens pilosa L. var. radiata Sch. Bip中发现蜂蜜。含有高浓度木犀草素和芹菜素。在一个地区检测到一个含有多氯联苯的样品和两个含有氯丹化合物的样品;然而，它们的浓度低于食品法规的要求。在琉球蜂蜜中发现了新颖的化学特征，包括来自B. pilosa的大量木犀草素和芹菜素，而观察到低OC污染。
