| 摘 要： | 通过颜色反应和紫外-可见光谱初步研究了15种颜色表现有代表性的蜡梅中、内被片的色素组成,并将颜色反应结果进行数量转化,采用类平均的方法进行Q型聚类分析。结果表明:蜡梅花色色素主要属黄酮类化合物,包括橙酮、查耳酮、二氢黄酮、二氢黄酮醇等;乔种和红心类蜡梅的内被片还含有花色素及其苷类。15个样品按照内被片有紫纹(乔种)、满布紫纹(红心),中被片白黄色、金黄色及其它被聚成了5类,这与实际颜色的表现基本一致。

| Abstract: | 15 samples from the inner and medium tepals of Chimonanthus praecox were selected for their representative phenotype in color to study the flower pigments.With the analysis of several color reactions and UV-visible spectra(200~600 nm),results were as follows:the main flower color pigments are attributed to flavonoids,including aurones,chalcones,flavonols and flavanones.Furthermore,anthocyanins and their anthocyanidins were contained in the red inner tepals or the ones with red speckles.In addition,the Q clu... |
