Certain potato cultivars are capable of producing anthocyanin pigments in the potato skin and flesh and those pigments have been shown, together with other phytochemicals, to promote good health. Six common anthocyanidins (cyanidin, delphinidin, petunidin, pelargonidin, malvidin and peonidin) were analyzed weekly for 15weeks in red- and purple-fleshed potato cultivars (Red Emma, Königspurpur, Valfi and Blaue de la Mancha) grown in field conditions using a validated LC-(+ESI)MS/MS method. Pelargonidin was the major type detected in red-fleshed cultivars whereas petunidin was the major type detected in the purple ones. Neither cyanidin nor delphinidin were found in any of the cultivars. The anthocyanidin levels observed were as high as 78mg/100g FW during tuber growth; however, fully matured tubers contained only 10-39mg anthocyanidins/100gFW. Anthocyanidin levels were moderately correlated with global solar irradiation (r<0.6252) but not with rainfall or daily temperature.
某些土豆品种的土豆皮和果肉能够产生花青素色素,这些色素与其他植物化学物质一起被证明有助于促进健康。在田间条件下种植的红色和紫色果肉土豆品种(RedEmma、Königspurpur、Valfi 和 Blaue de la Mancha)中,使用经过验证的 LC-(+ESI)MS/MS 方法,每周分析 15 周的 6 种常见的花青素(矢车菊素、飞燕草素、锦葵色素、天竺葵色素、锦葵色素和芍药色素)。在红色果肉品种中,天竺葵色素是主要类型,而在紫色果肉品种中,锦葵色素是主要类型。在任何品种中都没有发现矢车菊素或飞燕草素。在块茎生长过程中,观察到的花青素含量高达 78mg/100g FW;然而,完全成熟的块茎仅含有 10-39mg/100gFW 的花青素。花青素含量与太阳总辐射(r<0.6252)中度相关,但与降雨量或日温度无关。
