However, as a characteristic honey resource, the standard protocol used to identify the composition of <i>C. oleifera</i> honey has not been established yet. Previously, distinctive flavonoid has been shown as an effective marker to trace the botanical origin of honey. In this study, we examined the flavonoid types in <i>C. oleifera</i> honey and nine other monofloral honeys by using liquid chromatography tandem-mass spectrometry (LC-MS/MS) and compared the differences and identified eight distinct flavonoids in <i>C. oleifera</i> honey. Then, comparing the 8 flavonoids with the 14 flavonoids common to <i>C. oleifera</i> honey and nectar, two distinct flavonoids were identified in <i>C. oleifera</i> honey and nNutrientsKaempferitrin: A Flavonoid Marker to Distinguish <i>Camellia oleifera</i> Honey.PMC9867482CARS-44-KXJ1532172790Zheng YLi ZZhang YZeng ZShi WLiu BHuang QfalseKaempferitrin: A Flavonoid Marker to Distinguish <i>Camellia oleifera</i> Honey.<i>C. oleifera</i> is an economically important oilseed crop and medical plant.
