Analysis of organic acids in strawberry-tree (Arbutus unedo) honey showed the presence of an unknown acid as the main constituent. This compound was isolated and identified as homogentisic acid (2, 5-dihydroxyphenylacetic acid) by MS and NMR techniques. Its average content in honey was 378 +/- 92 mg/kg. Analysis of nectar confirmed the floral origin of the compound found in honey. Since this acid was not detected in any of the different monofloral honeys, it could be used as a marker of strawberry-tree (A. unedo) honey.
对草莓树（Arbutus unedo）蜂蜜中的有机酸进行分析，结果显示存在一种未知酸作为主要成分。通过质谱和核磁共振技术分离并鉴定出该化合物为尿黑酸（2,5 - 二羟基苯乙酸）。其在蜂蜜中的平均含量为378 +/- 92毫克/千克。对花蜜的分析证实了蜂蜜中发现的该化合物的花源。由于在任何不同的单花蜂蜜中均未检测到这种酸，因此它可作为草莓树（A. unedo）蜂蜜的标志物。
