Abstract:
This current research shows different analytical techniques used for describing vegetable tannin materials in various plant species grown in Sudan. It illustrates the evaluation of tannin content by both hide powder and combined techniques, total phenolic content by Combined, Folin Denis, and Hagerman and Butler methods. The result showed that of the six parts studied; five had over 10% tannin content and were thus suitable for commercial exploitation. Chromatographic techniques (Paper and Thin layer) designated and confirmed the present of mixed kind of tannin (gallo-catechol) except Acacia mearnsii which is of catechol type meaning contain condensed tannins only. The advantage of using this analytical technique, had similar yield of polyphenols attained with a lesser solvent feeding and a shorter removal time.
