The precious medicinal plant, Amomum tsao-ko Crevost et Lemarié, is the nectariferous plant from which the rare Amomum tsao-ko Crevost et Lemarié honey (ATH) is produced. Presently, chemical markers for authentication of this honey are not available due to the lack of data on its chemical composition. Here, we analyzed the volatile components and their odor activity values (OAVs), which revealed that the unique aroma was mildly flowery and fruity, accompanied by subtle sweet and fresh undertones. Since non-volatile chemicals are more reliable markers for routine authentication, we used a metabolomic approach combined with NMR-based identification to find and confirm a suitable compound to unambiguously distinguish ATH from other honeys. Isorhamnetin 3-O-neohesperidoside ranged from 3.62 to 9.38 mg/kg in ATH and was absent in the other tested honeys. In sum, the study uncovered unique chemical characteristics of ATH that will be helpful to control its quality.
珍贵药用植物草果，是稀有草果蜜（ATH）的蜜源植物。目前，由于缺乏其化学成分的数据，这种蜂蜜的化学标记物尚无法用于鉴别。在此，我们分析了挥发性成分及其气味活度值（OAV），结果表明，ATH 的独特香气具有温和的花香和果香，并带有微妙的甜香和清新的底色。由于非挥发性化学物质是常规鉴别更可靠的标记物，我们采用代谢组学方法结合基于 NMR 的鉴定，寻找并确认了一种合适的化合物，以明确区分 ATH 与其他蜂蜜。ATH 中异鼠李素 3-O-新橙皮糖苷的含量为 3.62 至 9.38 毫克/千克，而在其他测试的蜂蜜中则不存在。总之，该研究揭示了 ATH 的独特化学特征，这将有助于控制其质量。
