The mango stone kernel as a waste material can be utilized for the production of edible oil as an olein, whereas kernel stearin can either be utilized for the preparation of cosmetics and stearic acid or can also be consumed for edible purposes after the preparation of semi-solid fat, margarine and shortenings. Three varieties of mangoes Chaunsa, Sindhri and Desi have been selected to find out the percentages of peel and pulp (87.7-92.5 %), hulls (1.4-3.3 %), moisture (3.0-4.2 %), meal (2.8-4.9 %), oil (0.3-0.5 %) on the weight basis of mangoes. The oil yield on the weight basis of powdered dried kernel is (9.6-11.8 %). The statistical data of components is useful for the industrial exploitation of different parts of mangoes. The fatty acid composition of kernel oil of three varieties is also determined such as C12:0 (0.13-0.17 %), C14:0 (0.20-0.50 %), C16:0 (8.91-10.10 %), C16:0 (0.05-2. 70 %), C16:1 (0.05-2.70 %), C18:0 (42. 03-49. 20 %), C18:1 (30.27-39.05 %), C18:2 (3.18-6.21 %), C18:3 (3.24-4.72 %), C20:0 (0.45-0.83 %), C18:1 (0.12-0.32 %), C22:0 (0.24-0.64%), C22:1 (0.03-0.28 %), C24:0 (0.12-0.89 %) and C24:1 (0.02-0.13 %), which have not been claimed previously.
