在山东地区抽取10个养蜂场， 按照采蜜期3天、5天、8天、15天4个时间点进行样品采集，共收集洋槐蜂蜜样品120个，并对其中的18种酚类物质含量进行了测定。根据测定结果，18种酚类物质中有5种未检出，其余13种的含量变化在蜂蜜成熟过程中呈现3种不同的趋势。应用秩和分析对成熟/未成熟蜜组间酚类物质含量的差异进行了研究，发现了9种酚类物质成分呈显著差异，可作为区分成熟蜜与未成熟蜜的参考指标。

120 acacia honey samples were collected from 10 apiaries in Shandong area at 4 different time points in the 3rd, 5th, 8th, and 15th day, respectively.A total of 18 phenolic components were tested.According to the results, five phenolic components were undetectable.The remaining 13 phenolic components showed 3 different trends in honey maturation process.In accordance with the result of K-W test, 9 phenolic components were determined to be significantly different between the mature and immature honey groups, which provided useful references for determination of mature and immature honey.
