Utilization of Barks of <I>Terminalia</I> Species from Uttar Pradesh

Abstract

The studies have been made to explore the commercial potentialitie of barks of Terminalia arjuna, T. alata, T. bellirica and T. chebula from various parts of Uttar Pradesh. These barks were examined for their tannins and oxalic acid content. It was observed that the barks of T. arjuna and T. alata are most suitable for the production of oxalic acid. Barks of T. bellirica also had a high oxalic acid content, but a comparatively lower tannin cOntent. Barks of T. chebula, in general, contained lesser oxalic acid. Significant variation of oxalic acid and tannin coatents within the bark samples of the name species obtained from different regions have been observed.
