physiological function | salicylic acid carboxyl methyltransferase activity from Camellia sinensis provides the aroma compound methyl salicylate (MeSA) during the withering process of white tea. During the withering process for white tea producing, MeSA is generated by salicylic acid carboxyl methyltransferase (SAMT) with salicylic acid (SA), and the specific floral scent is formed | Camellia sinensis |
