Chromatogram of whole-grain wheat extract. A sample of the whole-grain wheat extract was run in negative ionization mode [(−)ESI]. Molecules were identified putatively: 1, C26H44O6, or C27H48O5, glycosylated sesquiterpene, and/or polyhydroxylated steroid; 2, C8H12O5, shikimic acid, or quinic acid derivative; 3, C39H66O9, glycosylated sesquiterpene, or a steroid; 4–6, C18H34O5, polyhydroxylated fatty acids; 7, C18H30O2, linolenic acid; 8, C16H30O2, hexadecenoic acid/palmitoleic acid; 9, C18H32O2, linoleic acid; 10, C16H32O2, palmitic acid; 11, C18H34O2, octadecenoic acid/oleic acid; 12, C18H36O2, stearic acid; 13, C20H38O2, eicosenoic acid; 14, C25H44O2, alkylresorcinol; 15, C27H48O2, alkylresorcinol; ESI, electrospray ionization.
