叶黄素和玉米黄质已被确定为类胡萝卜素，有助于预防常见的与年龄有关的眼病。因此，15马铃薯（Solanum tuberosum subsp.）tuberosum L.)育种系，栽培品种Atlantic，Spunta和Yukon Gold；和橙子果肉OR-4的类胡萝卜素谱进行了调查。从19个基因型中鉴定出紫黄质、新黄质、花青素、叶黄素、玉米黄质、β -隐黄质和β -胡萝卜素等7种类胡萝卜素。紫黄质和叶黄素是所有基因型中检测到的主要类胡萝卜素。新黄质和花青素分别占26%和63%的基因型。β -隐黄质、玉米黄质和β -胡萝卜素分别在5%、10%和16%的基因型中被发现。叶黄素在19.8 ~ 119.0马克杯之间变化。15个白肉或黄肉育种品系的鲜肉重量为100克（-1）。玉米黄质仅在1个品种中检测到低水平，在OR-4中检测到高水平。这三个品种都具有典型的黄肉土豆“Spunta”和“Yukon Gold”；而“大西洋”则有典型的白肉特征和少量的玉米黄质。本研究建立的类胡萝卜素基线数据为提高马铃薯叶黄素和玉米黄质的活性提供了信息。
Lutein and zeaxanthin are becoming established as carotenoids beneficial for protection against common age-associated eye diseases. Thus, 15 potato (Solanum tuberosum subsp. tuberosum L.) breeding lines, cultivars Atlantic,Spunta, and Yukon Gold; and orange flesh OR-4 were surveyed for carotenoid profiles. Seven carotenoids, including violaxanthin, neoaxanthin,antheraxanthin,lutein,zeaxanthin, beta-cryptoaxanthin,and beta-carotene, were identified in the 19 genotypes. Violaxanthin and lutein were the prominent carotenoids detected in all genotypes studied. Neoaxanthin and antheraxanthin were found in 26% and 63% of the genotypes, respectively. beta-Cryptoaxanthin, zeaxanthin, and beta-carotene were found in only 5%,10%, and 16 % of the genotypes, respectively. Lutein varied from 19.8 to 119.0 mug (.)100 g(-1) fresh weight across the 15 white- or yellow-flesh breeding lines. In contrast, zeaxanthin was detected at a low level in only one breeding line and at high level in OR-4. The three cultivars had profiles typical of yellow-flesh potatoes 'Spunta' and 'Yukon Gold'; while 'Atlantic' had a typical white-flesh profile and a trace of zeaxanthin. The carotenoid baseline data established in this study provide information for activities to enhance potato for lutein and zeaxanthin.
