The paper chromatography of oestrogens
Journal of Chromatography A, 1962Abstract The separations of steroid oestrogens achieved by paper chromatography have been reviewed with special reference to studied involving epimeric oestrogens and to oestrogens which have been isolated recently. Methods of detection of these compounds on paper chromatograms have also been discussed.

Journal of Chromatography A, 1962
Abstract A descending paper chromatographic method for water-soluble dyes is described in which a pyridine—isoamyl alcohol—ammonia solent system is used. The relatinship between dye constitution and chromatographic behavious has been investigated.

Paper chromatography of auxins and inhibitors in two Nicotiana species and their hybrid.
American-Eurasian journal of botany, 1965Auxins and auxin inhibitors from tissue extracts of normal Nicotiana plants, Nicotiana glavca, N. langsdorffii and their hybrid (which spontaneously produces tumors) were separated by ascending paper chromatography with n-butanol-distilled water.
