梅花花色色素种类和含量的初步研究

特征颜色反应和紫外 可见光谱表明 :梅花花色色素属于黄酮类化合物 ,不含查尔酮、噢、儿茶素、二氢黄酮、二氢黄酮醇等 ,而可能含黄酮、花色苷及其花色素等 ;红、白梅花的花色色素均含相同的非红色的黄酮类化合物 ;梅花的红色花色是源于花色素或 和其苷 ,且红的程度与其花色苷含量成正相关 ;梅花花色差异与总黄酮含量间似乎无明显规律性 .该文可为梅花花色的机理探索及其色素的分子结构鉴定提供参考

Preliminary study on the categories and contents of the flower color pigments of Prunus mume Sieb.Et Zucc

Specific color reactions and UV visible spectra indicate that the flower color pigments of Prunus mume Sieb. et Zucc. are flavonoids, excluding chalcones, aurones, catechins, flavanones, flavanonols and so on and probably including flavones, anthocyanin and its anthocyanidin and so on. The pigments of red and white flower colors contain the same non red flavonoids. The red flower color derives from anthocyanidins and/or their anthocyanins, and a positive relationship exists between the red flower color and the content of anthocyanins. It seems that there is no obvious law between the difference of flower colors and the content of total flavonoids. This paper provides a reference for the exploration on the mechanism of the flower colors and the identification of the molecular structures of the flower color pigments of Prunus mume Sieb. et Zucc.
