چکیده

Despite the fact, world leather industries are built on chromium tannage system, there is a growing interest of metal free tannages (chrome). This primarily owing to rising demand for tanning in industry. The goal this research paper was evaluate influences vegetable tannins materials retannage leather, by using Acacia nilotica ssp Adansonia pods (hydrolysable tannins) and Azadirachta indica bark (condensed tannins), estimating absorption physico-mechanical properties leather. results indicated that system give us products with tear strength 80 N/mm, tensile 55.5 N/mm2, elongation at break (75.3%). A re-tanning produced strong durable properties. On other hand, pre-tanning probably stiffens fiber network collagen molecules, blocking bigger molecules from diffusing into fibers collagen.

Impact of Hindon River Water on Selected Riparian Flora (Azadirachta Indica and Acacia Nilotica) with special Reference to Heavy Metals

The present study aims to identify the impact of polluted aquatic body i.e. River Hindon on two selected riparian flora i.e. Azadirachta indica and Acacia nilotica. During the course of study the average concentration of different metals in river water was found as Iron (Fe) 11.27ppm±3.50, Manganese (Mn) 4.00ppm±1.26, Cadmium (Cd) 0.08ppm±0.07, Nickel (Ni) 0.63ppm±0.17 and Zinc (Zn) 1.46ppm±0.3...

Effect of aqueous extract of Acacia nilotica ssp adansonii on milk production and prolactin release in the rat.

In view of the traditional belief that Acacia nilotica ssp adansonii (AN) can stimulate milk production in lactating women, experiments were performed to determine the effect of an aqueous extract of AN on milk production in rats. Female rats that received oral doses of aqueous extract of this plant during their first lactation produced about 59% more milk than controls (P<0.01). Pup weight gai...
