摘　　要：花色作为观赏植物的主要性状之一,既是衡量观赏价值的重要指标,也是区别植物种类的重要依据（张超等,2012）。研究表明：影响花色的色素主要有叶绿素（chlororphyll）、类胡萝卜素（carotenoids）、类黄酮（flavonoids）与生物碱（alkaloid）（赵昶灵等,2003;Tanaka et al.,1998）。金银花（Lonicera japonica）为忍冬科（Caprifoliaceae）Flower pigments of Lonicera japonica at different flowering stages were qualitatively and quantitatively analyzed using thin layer chromatography,UV photo-spectrometer and high performance liquid chromatography. The result showed that the changing trends of chlorophyll,chlorogenic acid and flavonoids content in L. japonica flowers were：primary bud green bud primary white white bud white flower yellow flower. The changing trends of luteoloside content were： green bud primary bud primary white white bud white flower yellow flower. The cartenoids content at the initial stages was： primary bud green bud primary white white bud white flower,but their content increased sharply in the yellow flower,and was ten times higher as white flower. The color change of L. japonica flowers from green to white was due to the decrease of chlorophyll,cartenoids and luteoloside. The flower color change from white to yellow was caused by the increasing of cartenoids.
