The air dried seeds of Sapodilla plum contain moisture 6.0%, hulls 51.7%, and kernels 42.3%. The hulls contain oil 0.45%, ash 0.77%, protein 2.05% (in defatted hulls) whereas the kernels contain oils 19.8%, ash 6.50% and protein 16.93% (in defatted kernels). The fatty acid composition of dark yellow coloured hull oil is lauric acid (5.38%), myristic acid (3.30%), palmitic acid (26.14%), stearic acid (9.3%), oleic acid (39.46%), linoleic acid (13.93%), and linolenic acid (2.36%) whereas light yellow coloured kernel oil contains palmitic acid (17.24%), stearic acid (10.14%), oleic acid (60.40%), linoleic acid (9.30%), linolenic acid (2.03%) and an unknown fatty acid (0.89%) respectively. The unsaponifiable matter is determined as sterols (23.7% and 20.1%) alcohols (32.5% and 33.3%) hydrocarbons (43.8% and 46.6%) in hull and kernel oil respectively. The hydrocarbons C15 - C29 (in kernel oil), alcohols C12 - C18 (in hull oil) and C16 - C18 (in kernel oil) respectively have been separated, identified and characterized by the application of thin layer and gas liquid chromatography. Palmityl and oleyl alcholos are found to predominate in both the oils.
