Etude par chromatographie liquide haute performance de la composition en acides citrique, malique et ascorbique des jus de differentes varietes d'agrumes marocaines

Citric, ascorbic and malic acids are very important in the formulation of drinks. These acids were separated and measured by high performance liquid chromatography in the Moroccan orange and lemon juices. The mobile phase was adjusted at an optimum pH of 2.15. Good chromatograms were obtained by coupling three RP18 columns of 25 cm of length. The absorbance at 210 nm and 250 nm, was used for quantification. Study of the repeatability gives coefficients of variation lower than 3.8.
