The contents of soluble biophenols such as protocatechuic, gentisic, vanillic, caffeic, syringic, p-coumaric, ferulic, salicylic, and cinnamic acids were screened and quantified from the adventitious roots of Panax ginseng by HPLC-MS. Control adventitious roots which showed the greatest accumulation of ferulic acid (0.09 mg/g DW) were observed in our experiments. An increase in the total soluble biophenol content of adventitious roots was observed 5 days after treatment with elicitor 200 μM/L methyl jasmonate (MeJa) i.e., 35 to 40 days of inoculation. Among the biophenols investigated, the salicylic acid content was higher (0.44 mg/g DW) in MeJa treated adventitious root culture in the bioreactor. MeJa might apparently increase soluble biophenols production in adventitious roots by enhancing the biosynthesis pathway from phenylalanine to salicylic acid and other simple biophenols. ©2005 Springer Science+Business Media, Inc.
