Anthocyanins identified in the pods from 15 okra cultivars using UHPLC-Q-Orbitrap HRMS (Ultra-High Performance Liquid Chromatography coupled with quadrupole Orbitrap high-resolution mass spectrometry). (A) Okra pods display multifarious colors and shapes in various cultivars. (B) UHPLC profiles of the anthocyanins extracted from the tender pods of the 15 okra cultivars. Major cleavage sites of delphinidin 3-O-sambubioside and cyanidin 3-O-sambubioside conformed by mass spectrometry were indicated by dashed arrow.
