dc.description.abstractEdible flowers have been used in the human diet with secular records in Asia, ancient Greece and Rome, medieval France, England and the Middle East region [1). Due to consumer's interest in healthier living habits, edible flowers have performed an increasingly important function. These flowers are abundant natural sources of phytochemical compounds around the world with health benefits [2).The aim of this study was to determine the individual profile of soluble sugars and glycosylated flavonoids in petals and respective infusions of four edible flower species (Dahlia· mignon, Rose damascena 'Alexandria' and R. Gallica 'Francesa' grafted on R. canina, Calendula officina/is L. and Centaurea cyanus L). The soluble sugars were determined by high performance liquid chromatography coupled to a refractive index detector (HPLC-RI) and quantification was performed using the internal standard (melezitose) method. The phenolic profile analysis was performed by LC-DAD-ESI/MSn. Fructose, glucose and sucrose were found in the petals and in the infusions of the different species. Fructose was the main sugar present in three of the studied edible flowers, except for the Calendula officina/is L. where sucrose was the predominant sugar. Dahlia and rose petals (10.24 ± 0.62 and 10.75 ± 1.05 g/1 00 g dry weight), and their infusions (0.19 ± 0.02 and 0.19 ± 0.01 mg/100 mL respectively) presented higher values of total sugars, while the centaurea petals (1 .5 ± 0.1 g/1 00 g) and its infusion (0 .14 ± 0.01 mg/1 00 mL) presented lower values. The phenolic profile, of dahlia sample presented a total of 21 compounds, the main being naringenin-3-0-glucoside. The rose petals presented 12 flavonoids (kaempferol- and quercetin-3-0-glucosides as major compounds). Calendula presented a profile with 13 phenolic compounds (isorhamnetin-3-0-rutinoside as the most abundant molecule) and centaurea flowers presented 14 polyphenols (apigenin-0-glucuronide as the most abundant). These results confirm the potential of edible flowers as a source of bioactive compounds and their applicability, not only as ingredients in gourmet cooking but also as sources of bioactive phytochemicals with interest for the pharmaceutical and food industries.pt_PT
