“…Thinlayer chromatography has been applied to minute amounts of alkaloids (721,790,1032,1247). Linear (90, 246-8, 374, 379, 503, 548, 735, 800, 947, 1187, 1234), radial (231,762), and centrifugally accelerated (239) paper chromatograms are developed, usually with buffered solvent systems. Succinyl cellulose paper has been tried (751).…”
