Three varieties of mangoes (Mangifera Indica) Challnsa, Sindhri, and Desl in Pakistan have been selected to find out unsaponifiable matter 1.5-2.31 %. It consists of hydrocarbons 8,6-9,8 % of carbon chain length CIl-C"" whereas, squalene 45,26-54.19 % is determined in these varieties, The primary fatty alcohols 11.5-12.3 % of carbon chain CIl-C", are also separated and identified, Octacosanol is the predominant alcohol in each of the variety. The sterols are separated by preparative TLC and identified as 4,4 dimethyl sterols 15,1-16.0 %, 4-methyl sterols 6,4-7.0 % and 4-desmethyl sterols 53,5-54,0 % and unidentified matter 2.5-3.0 %. Thin layer chromatography was used for separation and purification. whereas gas chromatography and spectroscopic techniques i,e" IR and MS were applied for identitication and characterization of various classes of compounds
