| description | Currently, the negative effects of unified and intensive agriculture are of growing concern. To mitigate them, the possibilities of using local but nowadays underused crop for food production should be more thoroughly investigated and promoted. The soybean is the major crop cultivated for vegetable oil production in Zambia, while the oil production from local oil-bearing plants is neglected. The chemical composition of oils and cakes of a three traditional oil plant used by descendants of the Lozi people for cooking were investigated. <i>Parinari curatellifolia</i> and <i>Schinziophyton rautanenii</i> oils were chiefly composed of α-eleostearic (28.58–55.96%), linoleic (9.78–40.18%), and oleic acid (15.26–24.07%), whereas <i>Ochna serrulata</i> contained mainly palmitic (35.62–37.31%), oleic (37.31–46.80%), and linoleic acid (10.61–18.66%); the oil yield was high (39–71%). <i>S. rautanenii</i> and <i>O. serrulata</i> oils were rich in γ-tocopherol (3236.18 μg/g, 361.11 μg/g, respectively). The <i>O. serrulata</i> oil also had a very distinctive aroma predominantly composed of <i>p</i>-cymene (52.26%), <i>m</i>-xylene (9.63%), γ-terpinene (9.07%), <i>o</i>-xylene (7.97), and limonene (7.23%). The cakes remaining after oil extraction are a good source of essential minerals, being rich in N, P, S, K, Ca, and Mg. These plants have the potential to be introduced for use in the food, technical, or pharmaceutical industries. |
