Composition and content of anthocyanins and flavonoids in purple-red,pink,and white petals of Bauhinia variegata L.
The composition,content,and structure of anthocyanins and flavonoids in purple-red,pink,and white petals of Bauhinia variegata L.were studied to lay a foundation for further investigations of the floral pig-ment mechanisms and molecular breeding of this species.The anthocyanins and flavonoids were analyzed using liquid chromatography-mass spectrometry(LC-MS/MS).In total,53 anthocyanins and 340 flavonoids were detected.However,the anthocyanins were markedly different among the different colored petals.Mal-vidin-3-O-galactoside,malvidin-3-O-glucoside,delphinidin-3-O-galactoside were higher in the purple-red petals than in the white and pink petals.Delphinidin-3-O-(coumaryl)-glucoside,malvidin-3-O-sophoroside,petunidin-3-O-(coumaryl)-glucoside were higher in the pink petals than in the purple-red and white petals.Pelargonidin-3-O-(coumaryl)-glucoside was higher in the white petals than in the purple-red and pink petals.The flavonoids also differed significantly among the different petals.Pelargonidin-3-O-sambubioside-5-O-glu-coside,pelargonidin-3-O-sophoroside,and delphinidin-3-O-sambubioside were almost not detected in the white petals and delphinidin-3-O-sophoroside was almost not detected in the purple-red petals,while peonidin-3-O-glucoside,peonidin-3,5-O-diglucoside,chrysoeriol-7-O-rutinoside-5-O-glucoside,and isovitexin-7-O-(6''-sinapoyl)glucoside were higher in the pink than in the white and purple-red petals.
