Differential accumulation of pelargonidin glycosides in petals at three different developmental stages of the orange-flowered gentian (Gentiana lutea L. var. aurantiaca)
Fig 2
ESI-MS/MS spectra of anthocyanins isolated from petals of Gentiana lutea L. var. aurantiaca.
The number from 1 to 11 corresponded with the anthocyanins characterized and listed in Table 1. The image in L corresponded to the basic structure of the anthocyanin molecule.
