In this study, the effects of farm additives on eight wild plants from Nyamira County, Kenya were evaluated for their release of iron, copper, calcium, potassium and magnesium. A hundred and sixty traditional medicinal practitioners were surveyed and found to use Solanum indicum, Carissa edulis, Urtica dioica, Clerodendrum myricoides, Aloe vera, Plectranthus barbatus, Bidens pilosa and Solanum mauense. Atomic absorption spectrophotometer was used to determine the total nutritional element contents in the plants while ultra filtration and physiologically based extraction tests were used to determine the release and solubility of the nutritional elements. The plants from areas with high use of farm additives were found to have statistically significant high total levels of copper from the area with no or little application. Elemental analysis of the molecular species fractions into < 3 kDa, 3-10 kDa, 10 kDa-0.45 μm and 0.45-5 μm mass fractions showed that the mass distribution of the elements in the plants depended on the element. The nutritional elements released by gastrointestinal digestion were more than those released aquatically. Farm additives had no significant effect on the levels of most nutritional elements determined and the plants can be used as mineral element supplements in the human body in addition to their therapeutic activity.

农场添加剂对肯尼亚野生植物某些营养元素潜在生物利用度的影响。

在这项研究中，评估了农业添加剂对肯尼亚Nyamira县的8种野生植物释放铁，铜，钙，钾和镁的影响。对一百六十名传统医学从业人员进行了调查，发现他们使用了印度茄，卡里萨可食，荨麻叶二叠纪，猴头菌，芦荟，凤尾蕨，Bidens pilosa和Solanum mauense。原子吸收分光光度计用于确定植物中总营养元素的含量，而超滤和基于生理学的提取测试用于确定营养元素的释放和溶解度。发现在不使用或很少使用的情况下，来自农场添加剂大量使用地区的植物的铜总量在统计上显着较高。对<3 kDa，3-10 kDa，10 kDa-0.45μm和0.45-5μm质量分数的分子种类组分进行元素分析，结果表明植物中元素的质量分布取决于元素。胃肠道消化释放的营养元素比水生释放的营养元素更多。农场添加剂对确定的大多数营养元素的含量没有明显影响，该植物除具有治疗活性外，还可用作人体中的矿物质元素补充剂。
