一般描述
紫黄质是一种从植物中获得的环氧化类胡萝卜素。它是一种橙色的天然叶黄素色素。
应用
紫黄质已被用作色素提取物的高压液相色谱（HPLC） 分析中的标准品/对照品，用于确认 Nt-AXT 植物视觉表型的高水平虾青素积累。
生化/生理作用
紫黄质是一种强抗氧化剂，也是岩藻黄质和β-大马酮等重要化合物的重要前体。它是叶黄素循环的非光化学荧光猝灭结构成分，可保护光合系统免受过量光照的影响。从空心菜中提取的紫黄质具有很强的2,2′-联氮双-3-乙基苯并噻唑啉-6-磺酸 （ABTS+）自由基清除作用，还可抑制脂质过氧化和红细胞溶血。因此，它有望用于各种医药和保健产品。
紫黄质是一种环氧胡萝卜素，是辣椒素的前体。它是参与绿色植物质体进化（氧进化）的三种叶黄素之一，并参与光诱导的相互转换，即紫黄质循环。9-顺式环氧类胡萝卜素（紫黄质）裂解为黄黄素是脱落酸生物合成的关键调控步骤。
