Metabolic pathway of phenylalanine, tyrosine and tryptophan biosynthesis. The metabolite in the dark green box represents the positively identified metabolite that matched to both mzCloud and ChemSpider compound databases, the orange box represents the putatively identified metabolite, the blue box represents the metabolite that relates to this pathway (not found in this study), and the box plots of identified metabolites are displayed beside the corresponding metabolites. TP, Triphala extracts group; C, control group.
