The quality evaluation of herbal products remains a big challenge. Traceable markers are the core concept of the authentication of herbal products. However, the discovery of traceable markers is labor-intensive and time-consuming. The aim of this study is to develop a convenient approach to rapidly screen the traceable markers for herbal product authentication.
Commercial Jing Liqueur and its 22 species of herbal ingredients were analyzed using HPLC-QTOF-MS and GC-MS to characterize nonvolatile and volatile chemicals. The acquired data were imported into MZmine 2 software for mass detection, chromatogram building, deconvolution and alignment. The aligned data were exported into a csv file and then traceable markers were selected using the built-in filter function in Excel. Finally, the traceable markers were identified by searching against online databases or publications, some of which were confirmed by reference standards.
A total of 288 chemical features transferred from herbal materials to Jing Liqueur product were rapidly screened out. Among them, 52 markers detected by HPLC-QTOF-MS were annotated, while nine volatile markers detected by GC-MS were annotated. Moreover, 30 of these markers were confirmed by comparing with reference standards. A chemical fingerprint consisting of traceable markers was finally generated to ensure the authentication and quality consistency of Jing Liqueur.
A strategy for rapid discovery of traceable markers in herbal products using MZmine 2 software was developed.
草药产品的质量评估仍然是一项巨大挑战。可追溯标记是草药产品鉴定的核心概念。然而,可追溯标记的发现既耗费人力又耗时。本研究的目的是开发一种便捷方法,以快速筛选用于草药产品鉴定的可追溯标记。
使用高效液相色谱-四极杆飞行时间质谱(HPLC-QTOF-MS)和气相色谱-质谱联用仪(GC-MS)对市售劲酒及其22种草药成分进行分析,以表征非挥发性和挥发性化学成分。将采集的数据导入MZmine 2软件进行质量检测、色谱图构建、去卷积和校准。校准后的数据导出到csv文件中,然后使用Excel中的内置筛选功能选择可追溯标记。最后,通过在在线数据库或出版物中搜索来鉴定可追溯标记,其中一些通过对照品进行了确认。
共快速筛选出288个从草药原料转移到劲酒产品中的化学特征。其中,通过HPLC-QTOF-MS检测到的52个标记物得到了注释,而通过GC-MS检测到的9个挥发性标记物也得到了注释。此外,通过与对照品比较,确认了其中30个标记物。最终生成了由可追溯标记组成的化学指纹图谱,以确保劲酒的鉴定和质量一致性。
开发了一种使用MZmine 2软件快速发现草药产品中可追溯标记的策略。
