Mango seed oil is an edible oil present in the seed kernel of Mangifera indica L. Mango seed kernel oil finds its application in the cosmetic industry, pharmaceutical industry, and food and confectionery industry due to its high stability and high presence of antioxidants. Mango is an important and popular tropical fruit consumed worldwide and is native to South-east Asia. Apart from direct consumption, mango pulp is used to make mango juice, jam, ice cream, and other dishes like aamras, pies etc. The mango seed also called as mango stone is discarded along with the peel as waste which leads to environmental pollution due to improper disposal. However, by using the seeds to extract oil, this waste can be utilised to obtain a valuable commodity. The oil can be extracted using hydraulic press, solvent extraction, and Soxhlet extraction. This paper focuses on the Soxhlet Extraction of the oil and more importantly the optimisation of the process to get the best yield of the oil. It was found that after optimisation of the parameters - Solvent, Duration, Particle size and Solvent-Solid ratio, 17.3 mL of oil was obtained from 100g of mango seed kernel
