49 different non-volatile compounds were determined in Spanish Arctostaphylos uva-ursi leaves using UPLC-ESI-Q-TOF with MS technology. Both positive and negative electrospray ionization were applied. MarkerLynx was proposed as a powerful tool to distinguish samples from eight wild populations of Spain by determining their non-volatile markers. Development of HRMS methods let to analysis of metabolites in plants. Antioxidant and antimicrobial capacities of different extracts were evaluated. Plant extract with the strongest antioxidant and simultaneous good antimicrobial capacity (Lierta) was chosen and incorporated in a multilayer packaging. Then, antioxidant capacity of the new packaging was evaluated and the efficient free radical scavenging properties were demonstrated.
采用 UPLC-ESI-Q-TOF-MS 联用技术，对西班牙越桔叶中的 49 种非挥发性化合物进行了测定。同时采用正、负离子电喷雾电离。提出了 MarkerLynx 作为一种强大的工具，通过确定其非挥发性标志物来区分来自西班牙 8 个野生种群的样品。高分辨质谱方法的发展使得对植物代谢物的分析成为可能。评估了不同提取物的抗氧化和抗菌能力。选择了抗氧化和同时具有良好抗菌能力的植物提取物（Lierta），并将其纳入多层包装中。然后，评估了新包装的抗氧化能力，并证明了其有效的自由基清除特性。
