manuka honey. This work reports the identification of a compound previously unreported in manuka honey by HPLC, and determination of the structure of the as 3,6,7 trimethyllumazine using NMR, MS, IR and UV/Vis spectroscopy. This assignment was confirmed by total synthesis. The natural product, renamed lepteridine, was only observed in manuka honeys and could potentially serve as a biomarker for genuine
麦卢卡蜂蜜是由Leptospermum scoparium的花蜜制成,由于其非过氧化物抗菌活性而赢得了科学和经济利益。由于存在伪造的麦卢卡蜂蜜,对真正麦卢卡蜂蜜的生物标记物的需求日益增加。这项工作报告了通过HPLC鉴定麦卢卡蜂蜜中以前未报道的化合物,并使用NMR,MS,IR和UV / Vis光谱法确定了3,6,7三甲基鲁嗪的结构。通过完全综合证实了该分配。仅在麦卢卡蜂蜜中观察到了天然产物,重命名为lepteridine,可以用作真正的麦卢卡蜂蜜的生物标记。
