Kinetics of the alkaline hydrolysis of flavonoid glycosides

  • M. D. Alaniya
Article

Summary

1. In a study of the kinetics of the alkaline hydrolysis of flavone glycosides it has been found that derivatives of 3,3′,4′,5,7-pentahydroxyflavone hydrolyze faster than derivatives of 3,4′,5,7-tetrahydroxyflavone and of 3,4′,5,7-tetrahydroxy-3′-methoxyflavone.

2. In the hydrolysis of diglycosides of 3,3′,4′,5,7-pentahydroxyflavones the maximum amount of intermediate product is formed after 2 min (3,4′,5,7-tetrahydroxyflavone glycoside), and in the case of 3,4′,5,7-tetrahydroxy-3′-methoxyflavone glycosides after 120–150 min.
