J. Planar Chromatogr. 9, 107-112 (1996). Examination of the adsorption properties and separating ability of silica modified by addition of sodium hydrogen carbonate. The retention of the chosen 20 alkaloids was examined by the use of a nonaqueous mobile phase and by optimization of the systems by changing the identity and concentration of the modifier. Detection under 254 or 366 nm or with Dragendorff's reagent. Results obtained in the study were used to determine programs for stepwise and multiple-development gradients suitable for the separation of a complex alkaloid mixture.
