cultures fed with precursors, namely L-Phe, L-Tyr, and cucumber juice, at different concentrations show Phe an 1.5, 2.1, and 1.6fold increase in rosmarinic acid accumulation within 48-72 h, respectively. In this study, we focused on the function of individual precursor on key enzymes involved in RA biosynthesis. The phenylalanine ammonia lyase activity was significantly upregulated after Phe feeding, while tyrosine aminotransferase and hydroxyphenylpyruvate reductase activities are improved with Tyr treatment. Rosmarinic acid synthase activity is significantly enhanced by all three precursors, overview |
