dc.description.abstract The versatility of the Neem tree (Azadirachta indica) is reviewed. This species, native to India, highly implanted in Sudan has tremendous potential for human use. Since Neem is a natural renewable resource producing extensive useful volatile oil, this research is concerned by extraction of volatile oil from Neem plant (Azadirachta Indica), and studies the chemical properties of extracted volatile oil and prepares cream with different concentrations of Neem oil, and tested as a mosquito repellent. Analysis of the cream as moisturizing cream satisfies the requirement of Sudanese Standards and Metrology Organization (SSMO). The volatile oil was extracted from Neem fruit by Soxhlet extraction using Petroleum ether as the extracting solvent which is removed by rotary evaporator. The percentage yield of oil extracted was (37.08%). The result of study of chemical properties showed that: the oil has an acid value of (2.127), peroxide value of (0.00), iodine value of (47.35) and Saponification value of (138.45). The cream was prepared using a combination of solid base of Paraffin oil, Vaseline, wax and talk powder. Gum Arabic solution was used as stabilizing agent.Cresol as colouring agent. Neem oil 2% and 4%concentration of the oil in volume/weight of cream was added to obtain the final cream product. The effectiveness of cream as a mosquito repellent, has been tested. The result indicate .That the cream efficiency is 64.5%and 36.4%for the 10%volume/weight and 5%volume/weight respectively.is moderately active as mosquito repellent at 10%volume/weight concentration of the oil. Its economic exploitation will be beneficial, particularly to the Third World. In recent years, some useful commercial products have been developed from Azadirchta indica, and more considerable, scope for future product development. With a different concentration a potentially commercial product is suggested en_US
