title: A rapid TLC autographic method for the detection of glucosidase inhibitors.
abstract: A new bioautographic assay suitable for the localisation of beta-glucosidase inhibitors present in a complex matrix is described. Enzyme activity was detected using esculin as the substrate to produce esculetin, which reacts with ferric ion to form a brown complex.
