“…It is noteworthy that the value of macro elements reported in this study is also higher than those of Ndukwe et al, [31] and Harry-Asobara and Samson [32] both results obtained from A. indica leave samples obtained from Abia State Nigeria; this may also emphasize the effect of provenance. Microelements are used in relatively small amounts and is made up of less than 0.1% of dry plant tissue; they perform a variety of functions as well as being component of enzymes, activation of enzymes and certain redox reaction in plant metabolism [50], the iron concentration was higher (minor concentration) in all the medicinal plants compared to other micro elements which all occurred in trace amount i.e. Zn, Cu, Mn which are also lower than those reported for other plants.…”

Medicinal plants have great importance in African medicine and are also used as precursors in drug discovery. The medicinal value of plants lie in their bioactive constituents which usually allow them to fight against several diseases. Plant-based natural constituents can be derived from any part of the plant like bark, leaves, flowers, roots, fruits, seeds. The mineral and phytochemical analysis of the leaves of Azadirachta indica, Parkia biglobosa and Leea guineensis were investigated. The leaves were collected from the Herbal Garden, Forestry Research Institute of Nigeria, Jericho hills, Ibadan, Nigeria and identified at Forest Herbarium Ibadan. Oyo State. The leaves were air dried and milled to powder using a medium-sized milling machine and stored in an air-tight container until needed for analysis. Phytochemical screening/analysis and mineral analysis were determined using standard analytical methods. Phytochemicals like Alkaloids, Flavonoids, Tannins, Saponins, Anthraquinone, Cardiac glycoside were determined. while Minerals, such as Potassium, Sodium determined using flame photometer; Calcium, Phosphorus, Magnesium, Iron, Zinc, Manganese, and Copper were determined using Atomic Absorption Spectrophotometer. Results indicates that the bioactive contents of the leaves varied significantly (p<0.05) among the medicinal plants. The phytochemical analysis showed that the three medicinal plants contained alkaloid, saponins, tannins, flavonoids, polyphenols, cardiac glycoside and anthraquinone in varying quantities with the trend: A indica > P. biglobosa > L. guineensis; the macro elements showed similar trend as the phytochemicals while the micro elements followed the trend: P. biglobosa > L. guineensis > A indica. These results conceivably indicate that the three medicinal plant are good source of essential minerals and phyto-nutrients which possess strong pharmacological activities and provide scientific credence for its therapeutic usage.

“…These activities disrupt the balance of nutrients and other ions in soil and this disrupts the normal functioning of the soil (Parjono et al, 2019;Tyopine et al, 2020). De ciencies of micronutrients are prevalent in all agricultural soils but the extent depends on soil type, cropping system and anthropogenic activities (Shukla et al, 2014, Nieder et al, 2018. Nutrient concentration above or below a critical range may lead to toxicity or de ciency of an element which may adversely impact plant physiological functions and productivity (Nieder et al, 2018).…”

Most upper-group (Groups 13-17) trace elements are toxic including those already confirmed as micronutrients considering the very thin margin between their adequacy and toxicity in the biosphere. The concentrations, distribution and relative enrichment were studied of some of these elements in 0-50-cm soil layer at Ikwo in southeastern Nigeria representing largely disturbed and rapidly evolving ecosystems of the humid tropical region. Samples was from the north (N), south (S), east (E) and west (W) zones with pronounced mining and agricultural activities, including a reference zone at the centre (F). The samples were taken from fallow lands in the dry season. The concentrations of the trace elements were determined using Inductively Coupled Plasma Atomic Emission Spectroscopy. Enrichment factor was calculated as the ratio of each element to that of Fe (as a reference element) in the soil. The elements had their highest concentrations in F-zone and lowest in N-zone, with top-bottom ranges as 21.00-10.75, 1.83-0.93, 10.90-5.58, 4.05-2.05, 4.97-2.54, 2.20-1.12, 17.75-9.09, 26.74-13.69, 4.41-2.26, and 1.89-0.96 mg kg–1 for Se, As, B, Al, Si, S, Sn, Sb, I and Br, respectively. Thus mining and agricultural activities, rather than leading to the build-up of these elements, tend to contribute towards reducing their levels in the rhizosphere. Enrichment factors indicated moderate-to-insignificant levels of the majority of the elements in the soils. Generally, the elements showed similar distribution and enrichment patterns across the five zones. These results suggest that, at their current modes and intensities in the humid tropics, mining and agricultural activities apparently may not pose any ecological hazards due to these trace elements.

“…Различные факторы, воздействующие на организм человека и животных, оказывают всестороннее влияние на процессы жизнедеятельности, в том числе и на обмен ультрамикроэлементов. В настоящее время все чаще стали уделять внимание именно взаимосвязи заболеваний различной этиологии с содержанием химических элементов в организме человека, в частности в крови [1].…”
