以云南野生黄牡丹为材料,通过特征显色反应、紫外—可见光谱扫描及高效液相色谱—质谱技术(HPLC-MS)对其花瓣中的色素成分进行了初步分析和鉴定.结果表明,黄牡丹花色素的组成包括类黄酮和叶绿素两大类,其中类黄酮类色素主要为查耳酮和黄酮、黄酮醇的混合物,包括2’,4’,6’,4-四羟基查耳酮(2’,4’,6’,4-tetrapydroxychalcone,THC)的2’-葡萄糖苷即异杞柳苷(isosalipurposide,ISP)及山奈酚、槲皮素、异鼠李素、金圣草黄素、芹菜素葡糖苷等.同时,基于花色素的组成信息,探讨了牡丹黄色花育种的策略,为黄牡丹花色素成分的进一步分离和鉴定奠定了基础,并为牡丹黄色花形成机理及黄色花育种的研究提供了理论参考.
