摘　　要：蓝色瓜叶菊开花从初现蕾到花被片完全展开分为6个阶段,用高效液相色谱-光电二极管阵列检测技术(HPLC-PAD)和高效液相色谱-电喷雾离子化-质谱联用技术(HPLC-ESI-MS)分析不同开花阶段花瓣中花青苷组成及含量。结果表明:在瓜叶菊蓝色品种中含有3种以上的飞燕草苷;蓝色瓜叶菊总花青苷和主要的花青苷开花前4个阶段表现为线性上升,其后3个阶段表现为线性下降。通过分析,认为瓜叶菊花青苷积累与变化规律是植物提高传粉效率的一种适应机制,同时这种机制也符合多年生植物充分利用营养物质的原则。We analyzed the composition and amount of anthocyanins in blue flowers of Senecio cruentus at different stages of flower development.High performance liquid chromatography with a photodiode array detector（HPLC-PAD） and HPLC-electrospray ionization-mass spectrometry（HPLC-ESI-MS） methods were employed for qualitative and quantitative analyses of anthocyanins.The results show that there are more than three kinds of delphinidins in the blue flowers of S.cruentus.The amount of anthocyanins in blue flowers of S.cruentus quickly increased before the 4th flower stage.The amount of anthocyanin and flower stages were positively correlated,but a negative linear relationship was found after the 4th flower stage.The results indicate that the variation of anthocyanins in blue petals of S.cruentus is a mechanism adapted to pollination and complies with the rule of using nutrition in perennial herbage.
