摘　　要：为建立一种快速测定万寿菊(Tagetes erecta)花瓣叶黄素含量的方法,利用色差仪测得万寿菊花瓣的亮度值L*、红绿值a*、黄蓝值b*,并计算a*/b*、(a*/b*)2、色度值、色调值和色光值等颜色系数,同时采用紫外-可见分光光度法结合HPLC法测定花瓣叶黄素含量,分析叶黄素含量与这些颜色系数的相关性,建立回归方程并进行验证。结果显示,万寿菊花瓣叶黄素含量与a*、a*/b*、(a*/b*)2、色调值和色光值极显著相关;用三次函数模型构建的万寿菊叶黄素含量与a*值之间的回归方程拟合程度最高,且叶黄素含量的预测值与实测值之间差异不显著。结果表明,基于a*值构建的三次函数模型可以快速、无损预测万寿菊花瓣叶黄素含量。The colorimeter was used to measure the values of L*(brightness),a*(redness-greenness)and b*(yellowness-blueness)in petals of marigold(Tagetes erecta)to establish a rapid method for determining the lutein content in petals of marigold.The color coefficients including a*/b*,(a*/b*)2,chroma value,hue value and shade value were calculated.UV-spectrophotometry combined with HPLC method was used to determine the lutein content in petals.The correlation between the lutein content and the color coefficients was analyzed.The regression equation was established and confirmed.The results showed that the lutein content in petals of marigold was significantly correlated with a*、a*/b*、(a*/b*)2,hue value and shade value.The regression equation between the lutein content and a*value constructed by cubic function model had the highest degree of fitness,and there was no significant difference between the predicted value and the measured value of the lutein content.It is indicated that the cubic function model based on a*value can quickly and non-destructively predict the content of lutein petals of marigold.
