High-performance liquid chromatography was used to determine carotenoids (beta-carotene, lutein, neoxanthin, and violaxanthin) and tocopherols of leaves, buds, and flowers of Tunisian Capparis spinosa. This plant shows strong resistance to hard environmental conditions, and it is one of the most commonly found aromatics in the Mediterranean kitchen. In this study, the means of the total carotenoids were 3452.5 +/- 1639.4, 1002 +/- 518.5, and 342.7 +/- 187.9 microg/g fresh weight (FW) in leaves, buds, and flowers, respectively. Lutein accounts for the high content. Violaxanthin provided the lowest portion of the total carotenoids. The principal form of tocopherol detected in leaves was alpha-tocopherol (20.19 +/- 10 mg/100 g FW). In buds and flowers, there were both alpha- (49.12 +/- 17.48 and 28.68 +/- 9.13 mg/100 g FW, respectively) and gamma-tocopherol (48.13 +/- 15.08 and 27.8 +/- 16.01 mg/100 g FW, respectively). The combined content of pro-vitamin A and vitamin E in capers encourages researchers to more explore and find developments for this plant.
采用高效液相色谱法测定突尼斯刺山柑叶片、芽和花中的类胡萝卜素(β-胡萝卜素、叶黄素、新黄质和紫黄质)以及生育酚。这种植物对恶劣环境条件具有很强的抗性,是地中海厨房中最常见的香料之一。在本研究中,叶片、芽和花中总类胡萝卜素的含量分别为3452.5±1639.4、1002±518.5和342.7±187.9微克/克鲜重(FW)。叶黄素含量较高。紫黄质在总类胡萝卜素中所占比例最低。在叶片中检测到的主要生育酚形式是α-生育酚(20.19±10毫克/100克FW)。在芽和花中,既有α-生育酚(分别为49.12±17.48和28.68±9.13毫克/100克FW),也有γ-生育酚(分别为48.13±15.08和27.8±16.01毫克/100克FW)。刺山柑中维生素A原和维生素E的综合含量促使研究人员对这种植物进行更多的探索和开发。
