Abstract: – The aim of the present work was to study the chemical compositions of aqueous extract of Neem (Azadirachtaindica) leaf in Sokoto. The results obtained showed the presence of Tannin at1.4%, Oxalate at 1.41mg/100g, Phytate at 6.12mg/100g, Saponin at 22.55%, Cyanogenic glycoside at 2.05mg/100g, Alkaloid at 12.22%, Trypsin inhibitor at 6.25%, Flavonoid at 32.06%, Moisture content at 2.12%, Ash conten at 10.8%, Fibre at 16.20%, Protein at 14.53%, Fat at 5.82%, Carbohydrate at 59.53%, Energy value at 1,399.39Kj/100g, Vitamin A at 19.695mg/L, Vitamin B1 at 3.7mg/L, Vitamin B2 at 3.51mg/L, Vitamin B6 at 358.71mg/L, Vitamin C at 3154mg/L, Vitamin E at 33.98mg/L, Zinc at 0.1572ppm, Sodium at 5.7302ppm, Magnesium at 0.5802ppm, Phosphorus at 8.52ppm, Calcium at 7.2875ppm, Iron at 3.68ppm and Potassium at 9.0ppm
These results indicated that neem leaf aqueous extracts may serve as a useful ingredient in dietof especially animals and may exhibit immunomodulatory as well as anti-inflammatory, antihyperglycaemic; antiulcer; antimalarial; antifungal; antibacterial; antiviral; antioxidant; antimutagenic and anticarcinogenic characteristics.

Neem also refered to as Nimba/Holy tree/Vembu/Arishtha/Indian neem tree/Indian lilac/Margosa tree is an evergreen tree which is abundantly found in most of tropical and sub-tropical countries including Nigeria. Genus Azadirachta has two species as per geographical distribution and A. indicais mostly native of Indian and Asian sub-continent. Tree has good growth rate and attains height approximately 15-20m and sometimes even upto 35-40m(Kumar and Navaratnam, 2013).
