Phytochemical and biological study of certain Terminalia species growing in Egypt

A comparative study of the lipid, fatty acids, protein and amino acid content of the fruits of four Terminalia species, viz., T.bellerica Roxb., T.arjuna W. and A., T.muelleri Benth. and T.myriocarpa Heurck and Muell. is carried out. Determination of the tannin content of the different organs; bark, stem, leaf and fruit, isolation and identification of ethyl gallate and gallic acid from the fruits of T. bellerica as well as apigenin-7 -O-glucoside and quercetin-3-O-glucoside from the leaves of the same plant is achieved. A toxicological study, pharmacological and antimicrobial screening of the alcohol and aqueous extracts of the fruits and bark of T. bellerica is also carried out
