Urinary Homogentisic Acid: Determination by Thin-Layer Chromatography
Clinical Chemistry, 1973 Abstract A new method is described for qualitative and quantitative determination of urinary homogentisic acid. The method involves extraction of urine with ethyl acetate, thin-layer chromatography of the extract on Silica Gel G, elution of the homogentisic acid into water, and color development with Folin’s phenol reagent. Absorbance is
