Isolation, characterizaton and acute toxicity study of Terminalia elliptica (Saj) gum, Buchanania lanzan (Chironji) gum and Albizia lebbeck (Siris) gum

Abstract

The current investigation was focused on the collection, isolation, purification and acute toxicity study of Saj (Terminalia elliptica) gum, Chironji (Buchanania lanzan) gum and Siris (Albizia labback) gum. Each gums were collected from the bark of the tree, isolated and evaluated for various parameters. The results showed the total ash content 3.23± 0.61 %, 3.54± 0.69 % and 4.53 ± 0.02 %, loss on drying 10.31 ±0.7%, 6.8± 0.50% and 8.41 ± 0.31%, viscosity (4% w/v aqueous solution) 42±0.95cps , 38 ±.61 cps and 77 ± 0.23 cps , Swelling index 91.00± 1.69 %, 89.42± 1.93 % and 128.94± 2.02 %, hausner’s ratio 1.23± 0.06, 1.18± 0.05 and 1.12± 0.03, compressibility index 19.04± 1.01 %, 15.73± 0.96 % and 12.86± 0.94 %, angle of repose 23.37±0.03 0 , 16.04±0.150 and 13.37±0.21 0 and pH 4.23 to 5.58 , 4.20 to 5.05 and 4.89 to 5.29 respectively for Saj gum, Chironji gum and Siris gum. Various qualitative photochemical tests confirmed the presence of carbohydrates and protein while absents of alkaloids, tannin, cardiac glycosides, terpenoids and steroids in all these gums.
