Bromatological Analysis and Antioxidant Capacity of &i&Hibiscus sabdariffa&/i& L. in Cuba

摘要

Towards authentication and quality assurance of medicinal plants, calyces of Hibiscus sabdariffa L. recollected from the Experimental Station of Medicinal Plants “Dr Juan Tomas Roig” between January and April 2016 were analyzed to determine its bromatological properties (moisture content; dry matter; fat; protein; total ash; mineral contents) and its antioxidant capacity using FRAP assay (24.4 μmol Fe 2) /100g of fre sh mass). Total ash (6.90%) and moisture content (10.05%) tested are within the World Health Organization (WHO) standards for crude drug from medicinal plants. Mineral contents expressed in mg/100g (Fe: 41.17; Ca: 1522.50; K: 2557.50) are higher than foods that are excellent sources of those nutritional elements. Magnesium (242.50) and Sodium (152.25) contents are satisfactory taking into account the importance of these macrominerals for human body.
