title: Capillary electrophoresis quantitation of l-L-folinic acid in the presence of its inactive d-L-form.
abstract: The diastereomers d-L and l-L-folinic acid were separated by capillary electrophoresis, using heptakis (2,3-di-O-methyl)-beta-cyclodextrin as a chiral active component in the background electrolyte. The method proved suitable for the quantitation of these compounds in one commercial pharmaceutical preparation.
