Abstract
PLANT pigments are compounds which are not volatile at the temperatures normally used in gas chromatography (up to about 250° C). The only reported, work in this field has been carried out using the methyl esters of flavonoid compounds1. In this work characterization of the pigments was attempted by the technique of analysis of the products of pyrolysis. The original design of the apparatus used for this work was described for the analysis of phenolic resins and rubber polymers2 and has since found many applications including the characterization of nonvolatile alkaloids3, polystyrene4, purines and pyrimidines5 and barbiturates6.
