The identification and purification of the branch chain hexose hamamel
ose (2-hydroxymethyl-D-ribose) from plant leaves is described. The pro
cedure includes metabolite extraction in acid and a series of isocrati
c HPLC separations. Amperometric detection of hamamelose is shown to b
e quantitative, having a detection limit below 1 nmol. Similar detecti
on of the related compound, 2-carboxy-D-arabinitol, and its monophosph
ate ester, yields unusually small peaks. (C) 1998 Elsevier Science B.V
