Acidic properties of flavonoid compounds and the choice of solvent for performing potentiometric analysis

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

In order to choose a solvent for performing potentiometric titration, the relative acidities of 22 flavonoids have been studied in water, methanol, acetone, dimethylformamide, and dimethyl sulfoxide. It has been established that the conditions of titration improve on passing from water in the following sequence of organic solvents: methanol < dimethylformamide < acetone < dimethyl sulfoxide.
