Abstract
A process for the biosynthesis of echinatin-4-glucoside comprises cultivating calli of Glycyrrhiza echinata L. (Leguminosae) in an appropriate nutrient medium. The echinatin-4-glucoside appears in both the calli and the culture broth and may be extracted and separated therefrom.
Claims6
A process for the production of echinatin-4-glucoside, represented by formula ##STR9## wherein R is a glucopyranosyl residue, comprising cultivating calli of Glycyrrhiza echinata L. (Leguminosae) in a nutrient medium until echinatin-4-glucoside is produced in the calli and culture broth, and extracting and separating the echinatin-4-glucoside from the calli and the culture broth.
