Radiogaschromatographie von Kohlenhydraten,Organischen Säuren und Aminosäuren aus Pflanzen

Radio gaschromatography of carbohydrates, organic acids and amino acids A method for the radio-gaschromatographic determination of carbohydrates, organic acids and amino acids as well as the simultaneous recording of the specific activity of radioactive labelled compounds of these fractions is described and its application to the analysis of plant extracts or protein hydrolysates demonstrated. The application of 0.05–0.1 mCi ¹⁴C/g fresh weight of plant material is enough to obtain a sufficiently strong labelling even in short-term incubation experiments (15 sec.), as for example in photosynthesis research.
