摘要：

In this paper the influence of C-7, C-4′, and C-5 substituent positions and of the substituent type on structural transformations and on the stability of 4-substituted flavylium compounds was studied. Stability of the flavylium chromophoric system was highest in 7,4′-dihydroxy-4-metliylflavylium chloride, out of four compounds studied, in a series of constant ionic strength buffer solutions (pH 2.00-11.00). © 1990 American Chemical Society.
