Abstract
Summary The affinitive capacities of quinoidal chalcones towards the flower tissues were compared by examining apparent differences in the recovery rate of the pigments from dyer's saffron C. tinctorius ) florets. Precarthamin is less extractable by non-polar solvents, while acetic acid and ammonia water rose its yield a little. Upon trituration of flowers, the solubility of precarthamin was increased considerably, the amounts of safflor yellows, on the other hand, were rather reduced by this treatment. The data are outlined correlating with the compartmental locality of the pigments in the floral tissues of the herbal plant.
