When either trans-cinnamic acid-2-^<14>C or quinic acid-G-^3H was administered to sweet potato root discs, each compound was incorporated into chlorogenic acid. Hydrolysis analysis revealed that trans-cinnamic acid-2-^<14>C and quinic acid-G-^3H were selectively incorporated into the aromatic and non-aromatic moieties of chlorogenic acid, respectively. Quinic acid-G-^3H was considered a more efficient precursor than trans-cinnamic acid-2-^<14>C, based on data of dilution values, incorporation percents and pool sizes in the tissue. No conjugates of trans-cinnamic acid and quinic acid were detected in discs administered trans-cinnamic acid-2-^<14>C or quinic acid-G-^3H. From these experimental results, a possible biosynthetic pathway for chlorogenic acid has been proposed.
