An investigation was made for the better analysis of non-volatile organic acids in one dimentional ascending paper chromatography by employing their alkaloid salts.
Artificial mixture of organic acids (oxalic, malic, malonic, citric, glycolic, fumaric, and succinic acid), assumed to be widely contained in food stuff, were developed in alternating basic solvent systems at room temperature after modification to their alkaloid salts (brucine, cinchonine, quinine, and strychinine salt). Satisfactory resolution was obtained using acid-base indicator mixed with alkaline permanganate solution as a detecting reagent.
