于紫色花和白粉色花鹿角杜鹃开花过程中全绿期、露红期、初花期、盛开期，采用超高效液相色谱–串联质谱技术，测定鹿角杜鹃花瓣代谢物的含量；通过正交偏最小二乘判别法（OPLS–DA）分析筛选出差异代谢物，利用KEGG数据库对差异代谢物进行富集分析，进一步筛选与花色相关的关键代谢物，通过相关性分析验证关键代谢物与鹿角杜鹃花色的相关性。结果表明：在鹿角杜鹃的花瓣中共检测到1057种代谢物，其中差异代谢物243种，差异代谢物在类黄酮和花青素代谢通路中显著富集；紫色花鹿角杜鹃花瓣中锦葵色素–3–O–葡萄糖苷的含量远高于白粉色花鹿角杜鹃的。推测锦葵色素–3–O–葡萄糖苷是鹿角杜鹃花瓣...

The purple flowers and white pink flowers of Rhododendron latoucheae were selected during the flowering process including all-green stage,showing red stage,early flowering stage and full blooming stage.Determination of metabolites of Rhododendron latoucheae petals was conducted based on ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).The differential metabolites were screened by orthogonal partial least squares discriminant analysis(OPLS-DA),and the key differential metabolites associated with flower color were screened by enrichment analysis using the KEGG databas...
