Abstract
The present study was conducted to compare the effect of photoperiod durations (16 h light: 8 h dark vs 22 h light: 2 h dark) on yield, antioxidant potential and secondary metabolites of wheatgrass from different wheat varieties. The increase in total chlorophyll, TPC, TFC, DPPH inhibition and FRAP values were observed for the wheatgrass grown under prolonged photoperiod. The average height of the wheatgrass was also increased under the prolonged photoperiod. The higher chlorophyll content was positively correlated with higher antioxidant potential. Comprehensive non-targeted metabolite analysis was also carried out by LC-MS to investigate the different classes of compounds in wheatgrass juice powder. The metabolomics revealed 516 features in positive mode, which includes organic acids, terpenoids, phenolic acids, flavonoids, alkaloids, vitamins, cyanogenic glycosides, nucleic acids, fatty acids, sugars, peptides and derivatives. The results showed that the wheatgrasses contain diverse compositional makeup and nutrient distributions. The volume of most of the metabolites increased under prolonged photoperiod. The study also provides the glimpse of metabolomics of wheatgrass which may be helpful in nutrition and health aspect
