Abstract
Analyses are given of the nutritional composition of tender leaves of three species of Chenopodium (C. album L., C. murale L. and C. opulifolium Shraeder) from different locations of southeast Spain (Almería). The proximate composition, mineral elements (Na, K, Ca, Mg, P, Fe, Cu, Zn and Mn), fatty acids, vitamin C, carotenoids and oxalic acid contents were determined. Low proportions of available carbohydrates were found. Vitamin C contents were high, especially in C. album (155mg/100g). Carotenoids were found in high proportion (12.5mg/100g) in C. album. Mineral element contents were higher than in other green leafy vegetables. Fiber amounts were also remarkable (4–6g/100g). The ω3 series of essential fatty acids were major in the three species (C. album, 45.33%). Oxalic acid values and ratios oxalic acid/(Ca + Mg) were moderate, being higher in C. murale. We believe that these species of Chenopodium could be used for nutritious purposes, due to the amount and diversity of nutrients they contain.
