摘　　要：利用切片观察法、显色法和比色法对佛焰苞中花色素的分布情况、组分及含量进行了初步分析。结果表明:红掌佛焰苞中主要含有类黄酮(包括花青素苷、黄酮和黄酮醇)、叶绿素和类胡萝卜素3类色素。大部分品种中类黄酮主要分布于上下表皮细胞中,‘萨维尔’等少数品种的栅栏组织中也有类黄酮分布;而叶绿素和类胡萝卜素则分布在栅栏组织中。各色系均含有类黄酮,红色系比其它色系含有更多的花青素苷,绿色系则含有叶绿素;参试品种中只有棕红色品种‘热带之夜’含有少量类胡萝卜素。花青素苷和叶绿素是佛焰苞显色的主要因素,总体上总花青素苷和叶绿素含量与颜色明度L*呈负相关,而与彩度C*呈正相关,即随着总花青素苷含量的增加,红色和粉红色佛焰苞的红色色调加强,叶绿素含量增加可使绿色和白色佛焰苞的绿色和黄色色调加强。The spathe color of 23 cultivars of Anthurium were divided into six groups： red, pink, green, white, yellow and mixed color group. The distribution of flower pigments in the Spathe tissue was observed and the flower pigments in Spathes were generally identified and quantified. The results indicated that flower pigments of Spathe mainly included flavonoids （including anthocyanins, flavones, and flavonols） ,chlorophyll, and carotenoids. The flavonoids of most cultivars mainly distributed in the both upper and lower epidermal cells,also in palisade tissue of some cultivars＇ Spathes such as ＇Xavia＇. The chlorophyll and carotenoids were found in the palisade tissues. All cultivars tested contained flavonoids. The red Spathes contained more anthocyanins than other cultivars, besides, the green Spathes contained chlorophyll. Only in Spathe of ＇Tropical Night ~, a little carotenoids were detected. The anthocyanins and chlorophyll were key factors for Spathe coloration. In general, total anthocyanins content （TAC） and chlorophyll content （TCh） showed negative correlation with color lightness （L^＊ ）, while the positive correlation with chroma （C^＊）. In red and pink spahes, the increase of TAC could enhance the red hue;while in green and white Spathes,the accumulation of chlorophyll might strengthen the green and yellow hue.
