THE CHEMICAL INTERACTION BETWEEN PRECARTHAMIN AND CELLULAR-COMPONENTS

The affinitive capacities of quinoidal chalcones towards the flower ti ssues were compared by examining apparent differences in the recovery rate of the pigments from dyer's saffron C. tinctorius) florets. Preca rthamin is less extractable by non-polar solvents, while acetic acid a nd ammonia water rose its yield a little. Upon trituration of flowers, the solubility of precarthamin was increased considerably, the amount s of safflor yellows, on the other hand, were rather reduced by this t reatment. The data are outlined correlating with the compartmental loc ality of the pigments in the floral tissues of the herbal plant.
