Abstract
Phytohormones, Indole acetic acid, Salicylic acid and Gibberellic acid, either alone or in combination was applied on wheat sprouts to improve its nutritional status. The experiment included estimation of total phenolic, flavonoids, peroxidase activity and phenylalanine ammonium lyase activity. Antioxidant activity was determined by DPPH and FRAP assay. The results showed an increase in phenolic compounds, enzyme activity and antioxidant activity after treatment with the phytohormones. Phytohormone combinations were found to be more effective as compared to pure treatments. UHPLC-ESI-MS analysis was used to identify compounds in the control and treated samples. Phenolic acids, polyphenols, simple sugars, amino acids, dipeptides, lipids and fatty acids were detected. A multifold increase in the levels of phenolic compounds was observed in the phytohormone treated wheat sprouts.
