Garcia-Jimenez, Pilar Rico, Milagros Del Rosario-Santana, Diana Arbona, Vicent Carrasco-Acosta, Marina Osca, David Antioxidants Alismatales Seeds Biomass Polyphenols Germination Phenols Chromatography, High Pressure Liquid Rhizome Plant Extracts Metabolomics Plant Leaves In this work, metabolite profiling of seeds and antioxidant analysis of fragments of two marine seagrasses, and were carried out to identify metabolite signature involved in seed viability and to evaluate the potential of fragments as a source of bioactive compounds. Using HILIC/QTOF-MS, UHPLC-MS and spectrophotometric analysis, seed metabolites and polyphenols and antioxidant activities, such as those of radical scavenging (RSA), reduction (FRAP, CUPRAC) and complexation (CCA), of rhizome fragments were evaluated. Metabolite comparison between seeds revealed differences across development stages (germinated and non-germinated) and seed types (dormant and non-dormant), providing insights into metabolic activity potentially associated with germination processes and seed viability. Furthermore, polyphenol analysis showed the highest content of caffeic acid in mature leaves (17.00 ± 0.02 μg g dw for and 98.00 ± 0.03 μg g dw for ). Total phenolic content was correlated with flavonoids and with reduction and complexation activities. The combination of radical scavenging activity and t was higher in than and also surpassed the commercial synthetic antioxidant BHA. We conclude and exhibit distinct seed metabolite profiles related to germination and type of seeds, and that fragments are rich in antioxidants, with potential as sustainable sources of bioactive compounds. |
