Quantitative determination of gallic acid and tannic acid from gallnut extract

Quercus infectoria gallae (oak gall) contain tannins which are characterized to have curative and anti-inflammatory properties.

A newly developed gallnut extract was prepared in a glycerin-water-mixture. To examine the quality of this extract a reliable, innovative HPLC method was worked out to determine the containing active ingredients.
