A new combination of four organic solvents is proposed for the optimization of TLC separations of basic drugs and alkaloids. The solvents are diethylamine (DEA), methanol (MeOH), chloroform (CHCl3) and ethylacetate (EtAc). They were selected from a c

A rapid quantitative determination of the individual glycoalkaloids solanine and chaconine is described. The glycoalkaloids were extracted by blending with methanol and the dry residues obtained were worked up by extraction withn-butanol. After separ
