[Abstract]  Carotenoids are ubiquitous pigments that play key roles in photosynthesis and also accumulate to high levels in fruit and flowers. Specific carotenoids play essential roles in human health as these compounds are precursors for Vitamin A; other specific carotenoids are important sources of macular pigments and all carotenoids are important anti-oxidants. Accurate determination of the composition and concentration of this complex set of natural products is therefore important in many different scientific areas. One of the richest sources of these compounds is the fruit of Capsicum; these red, yellow and orange fruit accumulate multiple carotenes and xanthophylls. This report describes the detailed method for the extraction and quantification of specific carotenes and xanthophylls. [摘要]  类胡萝卜素是在光合作用中起关键作用的普遍存在的颜料,并且在果实和花中积累到高水平。 特定类胡萝卜素在人类健康中起着重要作用,因为这些化合物是维生素A的前体; 其他特定类胡萝卜素是黄斑色素的重要来源,并且所有类胡萝卜素是重要的抗氧化剂。 因此,在许多不同的科学领域中,精确测定天然产物的复杂集合的组成和浓度是重要的。 这些化合物最丰富的来源之一是辣椒的果实。 这些红色,黄色和橙色果实积累多个胡萝卜素和叶黄素。 本报告描述了特定胡萝卜素和叶黄素的提取和定量的详细方法。
