• Mesophyll cells isolated enzymatically from Vigna angularis leaves were fed ^<14>C-glucose or ^<14>C-erythrose and the time-course of ^<14>C incorporation into shikimic and quinic acids was examined. When ^<14>C-glucose was fed to the cells, the highest radioactivity in quinic acid was observed after 10 hr of incubation, while that in shikimic acid was after 14 hr. In the experiment with ^<14>C-erythrose, the radioactivity in shikimic acid rose strikingly up to the 3rd hour, but ^<14>C in quinic acid increased gradually during the incubation. The incorporation of ^<14>C into shikimic acid was enhanced when unlabeled shikimic or quinic acid was supplied to the cells simultaneously with either ^<14>C-glucose or ^<14>C-erythrose, whereas that into quinic acid was not significantly increased by these alicyclic acids. The difference in incorporation rate of ^<14>C into quinic acid from that into shikimic acid was more conspicuous in the isolated mesophyll cells than in the epicotyls of V. angularis seedlings.
