Abstract

A new method for the gas-chromatographic multicomponent analysis of metabolites in biological material is described. It is an analytical procedure involving several extractions carried out under different conditions. In this procedure the metabolites are divided according to their functional groups and specific chemical behaviours into eight main fractions: lipids, hydrocarbons, organic acids, neutral substances, phenols, amines, amino acids and carbohydrates. Each of these fractions is derivatized; the components are separated and estimated by gas chromatography. This analytical system was applied to the determination of a number of metabolites in serum, urine, amniotic fluid, sperma, tissues and other biological materials.
