Extraction of essential neem oil from neem seed were carried by soxhelt extraction and simple distillation method using different types of solvents and parameters. Physico-chemical characteristics of the extracted oil were also determined by using classical wet chemical method. Results were generated in both techniques. Soxhlet extraction using hexane has 40.35%, using ethanol-hexane mixture of 60:40% volume proportions have 43.71%, using ethanol 42.65% and using methanol 42.89%. In simple distillation method results reveal that using hexane 42.35%, in methanol 39.5%, using ethanol 40.72% and using ethanol-hexane mixture of 60:40% has 41.26 %. For all solvent type particle size has 355μm, extraction time 1hr up to 3hrs and applied constant and varies temperatures. At smaller extraction time, hexane produced oil yield greater than from ethanol and methanol. In soxhlet extraction, ethanol not produced oil at one-hour extraction time. Thus, by effective determination of factors like particle sizes, solvent type, temperature, and time it is possible to investigate the result on the quality and quantity of neem oil.
