Metabolomic Analysis on Flavonoids in Bombax ceiba Petals with Different Colors
摘要
Abstract
In order to reveal metabolic mechanisms underlying flower color differences in Bombax ceiba and provide theoretical basis for development of new cultivars,B.ceiba petals with five different colors including dark red,red,orange red,orange yellow and yellow were used as experimental materials.Metabolomic analysis was performed on B.ceiba petals using high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)technology to analyze compositions and contents of flavonoids.Results showed that total of 137 flavonoids metabolites from six classes were identified,including flavones and flavonols(79),flavanones(19),anthocyanins(14),isoflavonoids(12),chalcones and dihydrochalcones(7)and flavonoids(6).Contents of flavo-noids and flavonols metabolites were the highest in all five petals,accounting for more than 65%,followed by flavanones and anthocyanins metabolites.Anthocyanin metabolie analysis revealed that cyanin chloride,keracy-anin chloride,idaein chloride and cyanidin 3-O-glucoside were the highest in dark red petals of B.ceiba.KEGG analysis indicated that differential metabolites in all five petals were significantly enriched in anthocyan-in synthesis pathway of anthocyanin.Primary metabolites responsible for red coloration of B.ceiba petals were anthocyanins,while yellow coloration might be associated with high levels of flavones and flavonols and low lev-els of anthocyanins.关键词
