      J. Liq. Chromatogr. Relat. Technol. 33, 179-190 (2010). TLC of salicylic acid and its derivatives, namely acetylsalicylic acid, salicylanilide, salicylaldehyde, salicylamide, salicylhydroxamic acid, methyl salicylate, phenyl salicylate, 3,5-dinitrosalicylic acid, 2,5-dihydroxysalicylic acid, 3-aminosalicylic acid, 4-aminosalicylic acid, and 5-aminosalicylic acid, on RP8, RP18 and HPTLC on RP18 and cyano phase with methanol - water; the content of methanol in mobile phase was gradually varied by 5 % from 20-100 %. Development in a chamber saturated for 15 min. Quantitative determination by scanning densitometry in absorption mode at the respective absorption maximum. The hRf values were recalculated on the RM values. The chromatograms were repeated in triplicate and mean hRf values were calculated. The results indicate that the chromatographic parameter of lipophilicity determined on RP8 and cyano phase may be used as a measure of lipophilicity of the investigated salicylic acid and its derivatives.
