Tryptophan,an essential amino acid and precursor to neurotransmitters like melatonin and serotonin, regulates moodand circadian rhythms. However, its quantification in mushrooms is scarce studied. An eco-friendly ultrasoundassisted extraction (UAE) method has been optimized to quantify tryptophan using ultra high-performance liquid chromatography with a diode array and fluorescence detector (UHPLC-DAD-Fl). Tryptophan levels were determined in 26 wild mushroom samples of the genus Lactarius and Boletus. The concentrations ranged from 0.042 mg/g to 0.742 mg/g. The extracts’ health benefits were assessed for antioxidant capacity using DPPH (17.7 % -71.6 %) and ABTS (7.2 % - 24.9 %) methods, while acetylcholinesterase (AChE) inhibitory activity ranged from13.1 % to 49.8 %. Promising results were obtained. Hierarchical cluster analysis demonstrated a correlationbetween tryptophan concentration, mushroom species, location, and extract properties, highlighting tryptophan’scrucial role in these mushrooms’ health benefits.
