A. Pavlov et M. Ilieva, The influence of phenylalanine on accumulation of rosmarinic and caffeic acids by Lavandula vera MM cell culture, WORLD J MIC, 15(3), 1999, pp. 397-399
Lavandula vera MM cell suspension culture was grown in Linsmayer-Skoog medi
um with different concentrations of phenylalanine. Adding phenylalanine to
the medium (0.1-0.5 g/l) enhanced accumulation of caffeic acid in parallel
with rosmarinic acid. When 0.3 g phenylalanine/l was added, the yield of ro
smarinic and caffeic acids reached 87 mg/l and 60 mg/l respectively, compar
ed with 68 mg/l and 4 mg/l in controls (without phenylalanine).
