Towards authentication andquality assurance of medicinal plants, calyces of , L. recollected from the Experimental Station ofMedicinal Plants “Dr JuanTomas Roig”between January and April 2016 were analyzed to determine its bromatologicalproperties (moisture content; dry matter; fat; protein; total ash; mineralcontents) and its antioxidant capacity using FRAP assay (24.4 μmol Fe,/100gof fre,sh mass). Total ash (6.90%)and moisture content (10.05%) tested are within theWorld Health Organization (WHO) standards for crude drug from medicinal plants. Mineral contents expressedin mg/100g (Fe: 41.17;Ca: 1522.50; K: 2557.50) are higherthan foods that are excellentsources of those nutritional elements. Magnesium(242.50) and Sodium (152.25) contents are satisfactory taking into account theimportance of these macrominerals for human body.,
