    • Abstract

       

      The Cambodia cotton flowers (G. hirsutum) contain a good amount of pigment (3%) in spite of their feeble ivory colour. In one sample the pigment was found to be mainly Quercimeritrin along with a small quantity of Quercetin, whereas in another sample collected next year Quercetin formed 75% of the total pigment and Quercimeritrin only 25%. In the nature of the pigments these flowers differ from the yellow American upland cotton (G. hirsutum) which have been reported to contain Quercimeritrin and Isoquercitrin. It is therefore concluded that the nature of the pigments vary with (1) the variety, (2) the locality, and (3) the season.
