Mineral composition of dry LINN pulp and seeds was evaluated on samples collected from three different agro-ecological zones of Uganda (Lake Victoria Crescent, and Eastern and West Nile). The objective of the study was to evaluate the mineral composition of pulp and seed samples from across Uganda's different agro-ecological zones and land use types. Separately grounded samples of pulp and seeds were analyzed for Zn, Fe, Mg, P, Na, K, and Ca. The univariate analysis of variance in the General Linear Model was used to compare differences in mineral composition. Treatment means were separated using Least Significant Difference (LSD) in Post Hoc Tests. The results showed that there were significant differences ( ≤ 0.005) in mineral composition levels of pulp and seed samples between the different agro-ecological zones with the exception of P and Na (for pulp). The pulp and seeds samples from the Lake Victoria Crescent zone and wild land use type had generally higher mineral levels than samples from other agro-ecological zones and different land use types. As mineral composition levels were generally higher in the seed than the pulp samples, consumption of seeds should be promoted. There is also need to conserve individual species both on-farm and in the wild population, but mineral concentrations (both pulp and seeds) were higher in the samples from the wild population, making them good for human and animal diets.
对从乌干达三个不同农业生态区（维多利亚湖新月地区以及东部和西尼罗河地区）采集的样本进行了干燥LINN果肉和种子的矿物质成分评估。该研究的目的是评估来自乌干达不同农业生态区和土地利用类型的果肉和种子样本的矿物质成分。分别对研磨后的果肉和种子样本进行锌、铁、镁、磷、钠、钾和钙的分析。使用一般线性模型中的单因素方差分析来比较矿物质成分的差异。在事后检验中使用最小显著差异法（LSD）来分离处理均值。结果表明，除了磷和钠（果肉中的）之外，不同农业生态区的果肉和种子样本的矿物质成分水平存在显著差异（≤0.005）。来自维多利亚湖新月地区和野生土地利用类型的果肉和种子样本的矿物质水平通常高于来自其他农业生态区和不同土地利用类型的样本。由于种子中的矿物质成分水平通常高于果肉样本，因此应提倡食用种子。还需要在农场和野生种群中保护各个物种，但是野生种群样本中的矿物质浓度（果肉和种子中的）更高，这使其适合人类和动物食用。
