Wild fruits are commonly consumed in the rural communities of South Africa. The information on their nutritionally important fatty acids is, however, limited. Three wild fruit species, , and from Limpopo Province were selected for evaluation of fatty acid content. Fatty acids composition of dried fruits of (Db), (Lk) and ripe and/or overripe (Sb) were evaluated by a gas chromatography-time of flight-mass spectrometer (GC-TOF-MS). Hexadecanoic acid (C16:0) was found in highest abundance in (57.73-73.55%), followed by (55.92-71.31%) and (46.31-62.05%), respectively. Octadecanoic acid (C18:0) was of second highest abundance, with 24.71-100% in , (31.03-41.60%) and (9.11-17.0%). The 9-octadecenoic acid (C18:1-9) was the major unsaturated fatty acid in both (5.33-18.82%), (8.22-8.92%), and (3.84-8.63%). The 9,-12-octadecadienoic acid (C18:2-6) was the major unsaturated fatty acid in (22.34%). The 9,-12,-15-octadecatrienoic acid (C18:3-3) was found in (3.51%) and (2.79%). From the results, saturated fatty acids were the most dominant, whereas mono- and poly-unsaturated fatty acids were the minor constituents. Therefore, presence of nutritionally important essential fatty acids from , and has been shown.
南非农村社区常食用野生水果。然而,关于其重要营养脂肪酸的信息有限。选择来自林波波省的三种野生水果物种,即、和,以评估其脂肪酸含量。通过气相色谱-飞行时间质谱仪(GC-TOF-MS)评估干水果(Db)、(Lk)和成熟和/或过熟的(Sb)的脂肪酸组成。在(57.73-73.55%)中发现十六烷酸(C16:0)含量最高,其次是(55.92-71.31%)和(46.31-62.05%)。十八烷酸(C18:0)的含量次之,在中含量为 24.71-100%,在(31.03-41.60%)和(9.11-17.0%)中含量为 31.03-41.60%。9-十八烯酸(C18:1-9)是和(5.33-18.82%)和(8.22-8.92%)中主要的不饱和脂肪酸,(3.84-8.63%)中也是主要的不饱和脂肪酸。9,12-十八碳二烯酸(C18:2-6)是(22.34%)中主要的不饱和脂肪酸。9,12,15-十八碳三烯酸(C18:3-3)存在于(3.51%)和(2.79%)中。从结果来看,饱和脂肪酸占主导地位,而单不饱和和多不饱和脂肪酸则是次要成分。因此,证明了、和中存在重要的营养必需脂肪酸。
