The paper electrophoretic separation of phloroglucinol derivatives in aspidium extract was carried out by a double migration method, using the Kolthoff buffer solution added with a small quantity of surface-active agent. Filicinrc acid was used as the standard and MFC values (distance moved by Aspidium constituent/distance moved by filicinic acid) were calculated. In the first migration at pH 7.0, flavaspidic acid was separated and the other constituents were separated in the second migration at pH 8.6. The spots were detected by coloring with diazotized sulfanilic acid, after pencil-marking of the fluorescence under ultraviolet rays.
