The present study describes the effect of a Phytophthora sojae 25-amino acid oligopeptide (Pep25) elicitor on the secondary metabolism of parsley cell cultures (Petroselinum crispum L.). HPLC analysis of the accumulated compounds in the elicitor-treated cultures revealed the expected accumulation of furanocoumarins (e.g. marmesin and bergapten) as well as various noncoumarin compounds which have not been described previously to occur in this cell culture. These compounds were isolated by preparative HPLC and identified by spectroscopic methods (MS, NMR) as 5-hydroxy- and 7-hydroxy-3-butylidenephthalides including two novel conjugates of the 7-hydroxy derivative, i.e. 7-O-glucoside and 7-O-(6'-malonylglucoside).
