The roots and rhizomes of licorice plants (genus Glycyrrhiza L.) are commercially employed, after processing, in confectionery production or as sweetening and flavouring agents in the food, tobacco and beer industries. G. glabra, G. inflata and G. uralensis are the most significant licorice species, often indistinctly used for different productions. Licorice properties are directly related to its chemical composition, which determines the commercial values and the quality of the derived products. In order to better understand the characteristics and properties of each species, a chemical characterization of three species of licorice (G. glabra, G. inflata, G. uralensis) is proposed, through an untargeted metabolomic approach and using high-resolution mass spectrometry. The statistical analysis reveals new possible markers for the analyzed species, and provides a reliable identification of a high number of metabolites, contributing to the characterization of Glycyrrhiza metabolome.
甘草属植物的根和根茎经加工后，在糖果生产中商业应用，或在食品、烟草和啤酒行业中用作甜味剂和调味剂。光果甘草、胀果甘草和乌拉尔甘草是最重要的甘草品种，常用于不同生产中，常常未作区分。甘草的特性与其化学成分直接相关，化学成分决定了衍生产品的商业价值和质量。为了更好地了解每个品种的特征和特性，本文提出通过非靶向代谢组学方法并使用高分辨率质谱对三种甘草（光果甘草、胀果甘草、乌拉尔甘草）进行化学表征。统计分析揭示了所分析品种新的潜在标志物，并可靠鉴定了大量代谢物，有助于甘草代谢组的表征。
