NMR Metabolome-Based Classification of Cymbopogon Species: a Prospect for Phyto-equivalency of its Different Accessions Using Chemometric Tools

Abstract Cymbopogon species are widely distributed worldwide and known for their high essential oil content with potential commercial medicinal benefits justifying inclusion in food cosmetics. Most received scant characterization regarding full complement of bioactive constituents necessary to explain activities. In this study, the metabolite profiles 5 species, C . citratus , flexuosus procerus martini nardus were characterized via NMR-based metabolomics. The results 13 shoot accessions revealed identification quantification 23 primary secondary metabolites belonging various compound classes. Multivariate analyses used classification, though found not successful discrimination based on geographical origin. Nevertheless, was particularly enriched neral, geranial, ( E )-aconitic acid, isoorientin, caffeic acid as major characterizing compared other while an unknown apigenin derivative appeared discriminate phenolic emphasizes its strong antioxidant activity, whereas accounts traditional use insecticide. This study affords first insight into compositional differences among species. Moreover, antimicrobial, insecticidal, antidiabetic, compounds identified that can be utilized biomarkers authentication.
