摘要：Proximate composition and physicochemical analyses were carried out on the seed and extracted oil of Annona muricata . The results showed that the seed contained 7.7% moisture, 8.5% crude protein, 9.7% ash, 5.2% crude fiber, 40% fat and 34.1% carbohydrate. The seeds were found to be good sources of minerals. Potassium (357.14±1.84 mg/100 g) was the highest, followed in descending order by Calcium (149.1±2.10 mg/100 g), Phosphorus (136.0 ±1.52mg/100g), Sodium (17.35±2.47 mg/100 g), and Magnesium (12.57±1.42 mg/100 g).The physical properties of the oil extracts showed the state to be liquid at room temperature. The oil was found to contain high levels of unsaturated fatty acids, especially oleic (up to 41.41%) and linoleic (up to 30.60% ). Annona muricata oil can be classified in the oleic-linoleic acid group. The dominant saturated acid was palmitic (up to 20.33%). The oil extracts exhibited good physicochemical properties and could be useful as edible oils and for industrial applications.
