Abstract

âº Dark treatment increased volatile phenylpropanoids/benzenoid (VPB) levels in tea leaves. âº The phosphate metabolites, shikimic, prephenic, and phenylpyruvic acids, deceased in dark treated leaves. âº Levels of amino acids including l-phenylalanine, a precursor of VPB, increased in dark treated leaves. âº Dark treated and untreated leaves differed in their volatile and non-volatile metabolite profiles.
