Abstract Wild halophytes are traditionally consumed in Tunisia as gourmet vegetables due to their salty taste and organoleptic proprieties. However, their nutritional composition is not deeply studied. The aim of this study was to characterize three Tunisian wild halophytic species (Arthrocnemum indicum (Willd.) Moq, Halocnemum strobilaceum (Pall.) M. Bieb., and Suaeda fruticosa Forssk) at two different phenotypic stages according to the seasonal variation. Amaranthaceae, is one of the well spread halophytes family shrubs in the world, mainly in Mediterranean countries. The studied wild halophytes are an interesting source of nutrients and could be considered as healthy foods with high levels of dietary fibers (7.63–10.14 g/100 g fw), protein (2.45–4.14 g/100 g fw), n-3 polyunsaturated fatty acids in green phenotypic stage (29.87 %–40.5 %) and n-6 polyunsaturated fatty acids in red-violet phenotypic stage (25.4 %–75.26 %), with particular relevance to linolenic acid content (20.7 %–75.22 %). These halophytes are also a good source of minerals, particularly sodium, calcium, potassium and magnesium, as well as vitamins C and E, with a major abundance of α-tocopherol.

突尼斯野生苋科盐生植物的再评价：两个不同表型阶段的营养成分变化

摘要 野生盐生植物因其咸味和感官特性而在突尼斯传统上作为美味蔬菜食用。然而，它们的营养成分并未深入研究。本研究的目的是根据季节变化在两个不同的表型阶段表征三种突尼斯野生盐生植物物种（Arthocnemum indicum (Willd.) Moq、Halocnemum strobilaceum (Pall.) M. Bieb. 和 Suaeda fruticosa Forssk）。苋科，是世界上广泛分布的盐生植物科灌木之一，主要分布在地中海国家。研究的野生盐生植物是一种有趣的营养来源，可被视为具有高水平膳食纤维（7.63–10.14 g/100 g fw）、蛋白质（2.45–4.14 g/100 g fw）、n-3 多不饱和脂肪酸的健康食品绿色表型阶段的脂肪酸 (29.87 %–40. 5 %) 和处于红紫色表型阶段的 n-6 多不饱和脂肪酸 (25.4 %–75.26 %)，尤其与亚麻酸含量 (20.7 %–75.22 %) 相关。这些盐生植物也是矿物质的良好来源，尤其是钠、钙、钾和镁，以及维生素 C 和 E，以及大量的 α-生育酚。
