It has been shown for the first time that [3-3H]oIeanolic acid glycosides formed in the cytosol of C. officinalis leaf cells are transported to the extracellular space in the form of pentaglucoside VI (44%), whereas glucuronides derived from [3-3H]oleanolic acid 3-O-monoglucuronide (29%) as well asa part of glucosides (24%) were transported into the cell walls.
