A volumetric method that involve a doubletitration to analyse the tannin content of vegetables substratum based on pine bar is developed. Specialize bibliography does not regard its analysis in this kind of matrix. An adaptation of technique proposed by AOAC, refered to tannin present in tea is realized. By means of Standard Addition Technique, the absence of matrix interference is proved, Results show an acceptable repeatibility (σ= ± 0,04).
