Sequential Distribution Analysis of Metabolites in Blue Morning Glory (Ipomoea indica) Petals by Matrix Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry

Hideyuki Kajiwara and Akemi Shimizu

Blue morning glory (Ipomoea indica) has a color gradient on its petals that change during flowering. Although anthocyanins were thought to be responsible for the color variations among varieties, their distribution and metabolite changes in petals that might be affected by anthocyanins color during flowering were not clear. The petals were analyzed by matrix assisted laser desorption/ionization time-of-flight mass spectrometry. Metabolites extracted from sequential disc cut samples from petal tissue showed that the metabolites, including anthocyanins, were not uniformly distributed in petals and their distribution changed during flowering
