(ii) Rf values
Rf. values for all the pigments were calculated and compared with those of known pigments.
The main criterion for identification was the value obtained for the absorption curves, as it is difficult to reproduce Rf. values exactly from one run to another in chromatography. No great reliance therefore was praced on the Rf. values obtained.
