An NMR-based approach for rapid differentiation of oak honeydew honey from all other honey types (floral and other honeydew honeys) was proposed. It is based on the identification of the signals of the protons and the carbon of the methylene group of quercitol in the (1)H and (13)C NMR spectra of honey. The presence of quercitol was supported by TOCSY spectroscopy. Quercitol is a deoxyinositol which is regarded as a good taxonomic marker for the genus Quercus. All samples of oak honeydew honey contained quercitol, while in floral honey samples and honeydew honeys from fir and spruce it was absent. In addition, the described approach is promising with respect to quercitol quantification in honey by qNMR.
提出了一种基于核磁共振（NMR）的方法，用于快速区分橡木蜜露蜂蜜与所有其他蜂蜜类型（花蜜蜂蜜和其他蜜露蜂蜜）。该方法基于在蜂蜜的（1）H和（13）C NMR光谱中鉴定槲皮醇亚甲基的质子和碳的信号。通过全相关谱（TOCSY）光谱证实了槲皮醇的存在。槲皮醇是一种脱氧肌醇，被认为是栎属的良好分类标记。所有橡木蜜露蜂蜜样品都含有槲皮醇，而花蜜蜂蜜样品以及来自冷杉和云杉的蜜露蜂蜜中则没有。此外，所描述的方法在通过定量核磁共振（qNMR）对蜂蜜中的槲皮醇进行定量方面很有前景。
