Background and Objective: Avocado pears (Persea americana) are tropical fruits. They are very nutritious foods and regular consumptionof the fruits has been associated with the reductions of cardiovascular and circulatory diseases. The extracts from fruit pulp and seeds canbe used as an alternative dietary supplement. In addition, they have been extensively used in traditional medicine for the treatment ofvarious diseases. This study examines comparatively the levels of fatty acids, phospholipids and phytosterols in the samples of Perseaamericana pulp and seed. Materials and Methods: The fatty acid, phospholipid and phytosterol compositions were determined fromthe pulp and seed samples prepared from the fruits of Persea americana using the gas chromatography method. Results: The levels ofsaturated and unsaturated fatty acids in the pulp and seed samples were: total SFA (33.74 and 22.29%); total UFA (66.27 and 77.71%);PUFA/SFA (0.71 and 1.83%); total EFA (25.50 and 40.51%), respectively. The total phospholipids present in the pulp and seed were 851.47and 117.30 mg/100 g, respectively. The concentrations of phytosterols were of low values except in sitosterol (373.55 and 37.79 mg/100g) and stigmasterol (45.61 and 5.59 mg/100 g) for the pulp and seed samples, respectively. Conclusion: The result revealed that the seedsample was richer in EFA and PUFA/SFA ratio compared to that of pulp while the values recorded for phosphatidylserine for the twosamples were too low and do not meet USFDA standard.
