摘要
本研究调查了尼日利亚埃邦伊州两个不同农业生态地点生长的油橄榄叶片中微量元素的组成差异。采用能量色散x射线荧光(ED-XRF)法,按照标准程序采集新鲜油橄榄干叶样品,分析其P、S、K、Ca、Mn、Ti、Cu、Mo、Fe、Zn、Ni、Re、Eu和Pb的含量。结果表明,两个地点的样品中所研究的元素含量不同,其中Pb含量相对较高。当样品中磷、钾、钙、锰、铜、铁和锌的平均含量与成人的每日需要量相比较,并与成人每日所需的油橄榄叶的预期摄入量相比较时,得出结论,油橄榄叶可以作为当地消费者的名副其实的这些元素的来源。采用F-检验和学生t检验,在95%的置信水平上(α = 0.05)检验了两个地点生长的油叶样品中微量元素浓度的显著差异水平。结果表明,虽然样品中所研究的元素的数量在组成上存在差异,但这些差异在95%的置信区间内并不显著(t exp < t crits)。关键词:微量元素,日需要量,油葵,ED-XRF光谱法,Mgbabor, okposii - okwu
Energy dispersive X-Ray fluorescence spectrometric study of compositional differences in trace elements in dried Moringa oleifera leaves grown in two different agro-ecological locations in Ebonyi State, Nigeria
This study investigated the compositional differences in trace elements in M. oleifera leaves grown in two different agro-ecological locations in Ebonyi State, Nigeria. Fresh samples of dried M. oleifera leaves were collected and analysed for P, S, K, Ca, Mn, Ti, Cu, Mo, Fe, Zn, Ni, Re, Eu and Pb using Energy Dispersive X-ray fluorescence (ED-XRF) spectrometry, following standard procedures. The results showed varying amounts of the studied elements in the samples from the two locations, with relatively high amounts of Pb. When the mean content of P, K Ca, Mn, Cu, Fe and Zn in the samples where compared to their daily requirements for adults and the expected quantity of M. oleifera leaves an adult will eat to achieve the daily requirements, it was concluded that the leaves could serve as veritable source of these elements to local consumers. Levels of significant differences in the concentrations of the trace elements in samples of M. oleifera leaves grown in both locations were tested at 95% confidence level ( α = 0.05) using F- and student’s t -tests. The outcome showed that although there are compositional differences in the amounts of the elements studied in the samples, these differences are not significant ( t exps < t crits ) at 95% confidence interval.
