Abstract

A sample of Blighia sapida seeds collected in Benin has been analysed and the results are compared to the scarcely available literature data. The chemical analysis of seed oil shows a saponification value of 145 and an iodine value of 66, consistent with the high mono-unsaturated fatty acids (FAs) content (63.8 wt%). The most interesting feature is the prominent concentration of eicosenoic acid (48.4 wt%). Arachidic acid being the main component within the saturated group, the C20 FAs fraction accounts for 68.4 wt%, thus making the peculiar composition of this oil. Among the unsaponifiable fraction (2.4 wt%), the major sterol is stigmasterol (54.6 wt%), surprisingly over passing beta-sitosterol. Tocols (338 ppm) contains mainly alpha- and gamma-tocopherol. Regarding the defatted cake, results show the prominent position of starch and a noticeable amount of proteins and fibers (44.2, 22.4, 15.6 wt%, respectively). Seventeen amino acids were identified together with valuable minerals (total ashes 3.5 wt%). Possible uses of oil and defatted cake are discussed.

摘要

对在贝宁收集的非洲荔枝种子样本进行了分析，并将结果与现有极少的文献数据进行了比较。种子油的化学分析表明，皂化值为145，碘值为66，这与高单不饱和脂肪酸（FAs）含量（63.8 wt%）一致。最有趣的特征是二十碳烯酸含量突出（48.4 wt%）。花生酸是饱和脂肪酸组中的主要成分，C20脂肪酸部分占68.4 wt%，因此构成了这种油的特殊成分。在不皂化物部分（2.4 wt%）中，主要甾醇是豆甾醇（54.6 wt%），令人惊讶的是其含量超过了β-谷甾醇。生育三烯酚（338 ppm）主要含有α-生育酚和γ-生育酚。关于脱脂饼粕，结果显示淀粉占突出地位，还有大量蛋白质和纤维（分别为44.2 wt%、22.4 wt%、15.6 wt%）。共鉴定出17种氨基酸以及有价值的矿物质（总灰分为3.5 wt%）。文中还讨论了油和脱脂饼粕的可能用途。
