Differential accumulation of pelargonidin glycosides in petals at three different developmental stages of the orange-flowered gentian (Gentiana lutea L. var. aurantiaca).

ABSTRACT: Corolla color in Gentiana lutea L. exhibits a yellow/orange variation. We previously demonstrated that the orange petal color of G. lutea L. var. aurantiaca is predominantly caused by newly synthesized pelargonidin glycosides that confer a reddish hue to the yellow background color, derived from the carotenoids. However, the anthocyanin molecules of these pelargonidin glycosides are not yet fully identified and characterized. Here, we investigated the regulation, content and type of anthocyanins determining the petal coloration of the orange-flowered G. lutea L. var. aurantiaca. Anthocyanins from the petals of G. lutea L. var. aurantiaca were characterized and quantified by HPLC-ESI-MS/MS (High-performance liquid chromatography-electrospray ionization-tandem mass spectrometry) coupled with
