Abstract
The extraction of oil from mango seeds was investigated using a Soxhlet Extractor. Mango seeds were collected, dried and grounded into powder. Hexane and ethanol were used to extract the oil at varying time of extraction of 4, 5, 6, 7 and 8 hours, respectively. Result shows that yield is time dependent, as increase in time of extraction results into increase in yieldwhere the least time of 4hrs yielded an average of 4.00 % and 8hrs yielded an average of 13.06 % for hexane. While the use of ethanol at 4hr and 8hrs only yielded 1.99 % and 8.22 %.Thus the use of hexane achieved the maximum yield (13.06 %) of oil extracted. The effects of time and extraction solvent on the yield of oil was investigated by using a 22 factorial design and, result shows that factor ‘A’ which is time, produces the greatest effect (7.665) in the yield of mango than factors ‘B’ (3.335) being solvent and ‘AB’(1.335) being interaction between solvent and time. The effect of the extraction solvent on the physicochemical properties was also investigated where theoil extracted with hexane was found to possess better overall quality than the ethanol extracts, asits acid value, saponification value, ester value, refractive index and specific gravity were 5.61mgKOH/gOil, 207 mgKOH/gOil, 201.39mgKOH/gOil, 1.443 and 0.909, respectively as against 30.30mgKOH/gOil, 205 mgKOH/gOil, 174.70mgKOH/gOil and 0.909, respectively of ethanol. The results didn’t only show that hexane gives a higher yield of oil than ethanol but also revealed that hexane is a much better solvent for the extraction of mango seed oil.

The kernel can be ground into kernel powder for oil extraction.The oil is semi-solid at room temperatures, but melts on contact with skin, making it appealing for baby creams, heat-care balms, hair products and other moisturizing products(Sivkishen, 2014)
Determination of yield of oil For the two extraction solvents, hexane and ethanol, the yield of oil is shown below. (Detailed calculations are shown in appendix C)
Summary
The extraction of oil from mango seeds was investigated using a Soxhlet Extractor. Mango seeds were collected, dried and grounded into powder. The ripe widely in the world (Singh, 1960) It is one of the fruit is variable in size and colour, and may be most extensively exploited fruits for food, juice, yellow, orange, red or green when ripe, depending flavour, fragrance and colour and is a common on the cultivar (Fahimdanesh & Bahrami, 2013). The fruit of the Mango is never totally consumed or processed because the seed is protected by a hardened shell (endocarp). This seed is majorly disposed of after consumption but could besubjected to industrial processing.(Pomeranz, Methods
