DIGALLIC ACID

Digallic acid was prepared by partial acid hydrolysis of tannic acid and purified by Counter Current Distribution.In water and methanol solution digallic acid is present in two isomeric equilibrium forms which were named meta and para digallic acid.Meta digallic acid, the main component, is stable in ether and acetone solution.The above was proved by HPLC, GC-MS and NMR experiments on digallic acid and on its permethylation product.
