Biotransformation of phenylcarboxylic acids by plant cell cultures
A suspension culture of Glycyrrhiza echinata converted benzoic acid into its glucosyl ester. Suspension cultures of Aconitum japonicum, Coffea arabica, Dioscoreophyllum cumminsii and Nicotiana tabacum, transformed benzoic acid into its gentiobiosyl ester in addition to the glucosyl ester. The suspension cultures of A. japonicum and G. echinata converted phenylacetic acid into the esters attached to the C-6 position of glucose, that is, 6-0-phenylacetyl-D-glucose and ethyl 6-0-phenylacetyl-ß-D-glucopyranoside. That of D. cumminsii converted phenylacetic acid into the glucose este and also into phenethyl ß-D-glucopyranoside showing glucosylation after the reduction of the carboxylic group. These suspension cultures converted cinnamic acid into p-coumaric acid and its glucosyl ester and p-coumaric acid into its glucosyl ester. However, the conversion of caffeic acid was not observed. The suspension cultures of A. japonicum and C. arabica converted 3-phenylpropionic acid into its gentiobiosyl ester. On the other hand, the culture of D. cumminsii did not produce the glycosyl ester but instead 3-(4-hydroxyphenyl) propionic acid was formed, thus showing hydroxylation capability.
