Chemical characterization and bioactive compounds of an unconventional vegetable - Erechtites valerianifolia (Wolf) DC.

Abstract Erechtites valerianifolia (Wolf) DC is an unconventional vegetable found in the Brazilian Atlantic Forest. Is consumed in high proportions by the population living in this biome. The objective of this study was to investigate the general chemical composition, occurrence and content of carotenoids, vitamins (C and E) and minerals in this vegetable. By the micro-Kjeldhal method it was determined proteins. It was determined total dietary fiber (TDF) by non-enzymatic gravimetric method. Carotenoids and vitamins were determined by high performance liquid chromatography (HPLC). In inductively coupled plasma-atomic emission spectrometry (ICP-AES) it was determined minerals. E. valerianifolia presented concentrations of TDF (3.7 g 100 g-1), ash (0.9 g 100-1), lipids (1.4 g 100-1), carbohydrates (2.9 g 100-1), proteins (1.3 g 100-1), caloric density (29.2 kcal 100-1), Vit. A (373.9 µg 100-1 RAE), K (561.2 mg 100-1), Ca (79.5 mg 100-1) and Fe (21.6 mg 100-1). It is considered that this vegetable is source of Ca, good source of fiber and K, and an excellent source of pro-vitamin A, Mn, Se, Fe, Mo and Cu, which may reduce food and nutritional insecurity in the population, mainly in the region where this species is found.
