dc.description.abstractNumerous plants have been used all over the world and in addition to the food properties, their consumption seems to be associated with different beneficial properties for consumers’ health. In this way, several scientific studies have been carried out with the objective of confirming these properties besides the assessment of their nutritional quality1. Hibiscus sabdariffa L., is an annual or perennial plant with red stems and calyces, belonging to the Malvaceae family. It is cultivated mainly in the tropical and subtropical areas of both hemispheres2. The present study aimed to perform a targeted metabolites’ analysis (free sugars, organic acids, tocopherols and fatty acids) of H. sabdariffa dried calyces (Guinea-Bissauan origin), as well as the individual phenolic composition of its infusion and hydroethanolic extracts. Free sugars were identified through an HPLC-RI system, the organic acids by UFLC-PDA, tocopherols by HPLC-fluorescence, fatty acids by GC-FID and the individual phenolic compounds were analysed through HPLC-DAD-ESI/MS. Glucose and quinic acid showed the major concentration for sugars and organic acids, respectively. Palmitic acid and α-tocopherol were the most abundant lipophilic compounds. In the individual phenolic profile, thirteen compounds were identified, five phenolic acids and flavonols, and three anthocyanins. The hydromethanolic extract presented all the identified compounds, while the infusion revealed the presence of twelve molecules, with the absence of caffeic acid. In general, the hydroethanolic extraction seems to have favoured the extraction of non-anthocyanin phenolic compounds, while the infusion was the ideal methodology for the anthocyanins’ extraction. Nevertheless, 3-O-caffeoylquinic acid was the major non-anthocyanin compound, while, delphinidin-3-O-sambubioside was the most abundant anthocyanin, in both extracts. This study demonstrates the high potential of this species highlighting its usage as a functional food or beverage, and as a source of a possible nutraceuticals and natural pigments, giving an added value for future applications in several industrial sectors.pt_PT
