ResumoRoot cultures of Panax ginseng are able to convert (RS)-2-phenylpropionic acid into (RS)-2-phenylpropionyl β-d-glucopyranoside, (2RS)-2-O-(2-phenylpropionyl)-d-glucose, (2S)-2-phenylpropionyl 6-O-β-d-xylopyranosyl-β-d-glucopyranoside and a myo-inositol ester of (R)-2-phenylpropionic acid. The primeverosyl ester and myo-inositol ester were formed stereoselectively at C-2 from the racemic mixture. The conversion into glucosyl esters was very high at ca 90% and the total conversion reached 100% at day three. About a half of the products were excreted into the medium. Compared with the root culture, the callus showed lower glycosylation ability.
