Individual phenolic acid contents from the extractions of the germinated spelt (Triticum spelta) seeds, as the extractable and bound phenolics from direct solid-phase extraction (SPE), and for the free, soluble conjugate and bound phenolics from the liquid-liquid extraction without (LLE) and with SPE (LLE + SPE) purification. Data are means ± SD. Different letters within the same phenolic acid as extractable and (free + soluble conjugate) or bound indicate significant differences (p < 0.05; Duncan’s multiple range tests).
