A comparative UPLC-orbitrap-MS-based metabolite profiling of three Pelargonium species cultivated in Egypt. | LitMetric

AI Article Synopsis

  • Various Pelargonium species are primarily grown for essential oils in perfume and ornamental use, but their non-volatile compounds haven't been widely studied.
  • This research utilized Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS) to analyze and identify metabolites in three species: P. graveolens, P. denticulatum, and P. fragrans.
  • A total of 154 metabolites were identified, revealing important chemical compounds and highlighting the potential for these species in therapeutic uses and authenticity verification.

Article Abstract

Several Pelargonium species are cultivated mainly to produce essential oils used in perfume industry and for ornamental purposes. Although the chemical composition and biological activities of their essential oils were extensively investigated, there is limited information about the chemical composition of their non-volatile constituents. In this study, we report an Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS)-based metabolomics approach for the annotation and analysis of various metabolites in three species; P. graveolens, P. denticulatum, and P. fragrans utilizing The Global Natural Product Social Molecular Networking (GNPS) and multivariate data analyses for clustering of the metabolites. A total of 154 metabolites belonging to different classes were annotated. The three species are good sources of coumarins, benzoic acid derivatives, organic acids, fatty acids, and phospholipids. However, the highest level of flavonols (mono- and di-O-glycosides) and cinnamic acid derivatives was found in P. graveolens and P. denticulatum, whereas tannins and flavone C-glycosides were abundant in P. fragrans. The metabolic profiles clarified here provide comprehensive information on the non-volatile constituents of the three Pelargonium species and can be employed for their authentication and possible therapeutic applications.
