The contents of soil microelements can affect the growth, yield and quality of tobacco, but it is not clear of the status quo of soil microelements in tobacco fields in Liupanshui city. In this study, soil samples of the plough layers (0 - 20 cm) were collected from January to March in 2021 from 500 typical tobacco fields in Liupanshui City (100, 180 and 220 fields in Zhongshan, Shuicheng and Panzhou, respectively), the particle size composition, pH, the contents of organic matter (OM), available boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn) were measured and discussed. the results show that the mean contents of B, Cu, Fe, Mn, Mo and Zn are 0.92, 2.55, 66.47, 47.26, 0.39 and 3.96 mg/kg, respectively, and among which, B, Cu and Zn are at the high grades while Fe, Mn and Mo are at the very-high grades. There are significant differences in B, Fe and Zn among the three regions, while Cu is significantly different between Zhongshan and Shuicheng, Mn is significantly different between Panzhou with Zhongshan and Shuicheng, and Mo is significantly different between Zhongshan and Panzhou. The proportions of fields deficient in microelements are relatively low, no field is Fe-deficient, and the fields deficient in Mo, B, Cu, Zn and Mn are only account for 10.40%, 9.40%, 7.40%, 2.80% and 2.00% of the total fields respectively. B-deficient fields (green and light green colors, the same below) are mainly scattered in the northwest of Zhongshan and in the north and south of Panzhou, Cu-deficient fields mainly in the middle of Shuicheng and Panzhou, Mn-deficient fields mainly in northern Zhongshan, central Shuicheng and north of Panzhou. Mo-deficient fields are mainly in the middle of Shuicheng and the middle and east of Panzhou, while Zn-deficient fields are mainly in the middle of Shuicheng and the middle and east of Panzhou. Altitude is negatively correlated with Mn (P < 0.05), pH is negatively correlated with B (P < 0.05), Fe and Mn (P < 0.01

Background: Moringa oleifera plant is popularly known for its rich phytoconstituents and nutritional value and important medicinal values in both traditional and modern systems of medicine. We explored the present study for measurements of microelements, amino acid, phenolic content in hydro-al-coholic flower and leaf extracts of Moringa oleifera along with anti-diabetic activity in Streptozotocin (STZ)-induced diabetic male Wistar rats. Methodology: The micronutrients were determined by using atomic absorption spectrophotometer at 285 nm and 422 nm for Calcium (Ca), phosphorus (P), Iron (Fe), and Zinc (Zn), etc. The trace elements were also measured by spectrophotometer. The essential amino acid was determined by using Amino acid analyser. The total phenolic content in hydro-alcoholic extracts (flower and leaf) M. oleifera measured the absorbance at 760 nm by UV spectrophotometer. The screening of anti-diabetic activity HAFE and HALE of Moringa oleifera at two different dose of 100 and 200 mg/kg b.w. for 21 days were performed by determining the changes in biochemical parameters. Result and Discussion: The results revels that the presence of micronutrients, trace elements and amino acids in both flower and leaf of M. oleifera. The hydrolaocholic extracts of HAFE and HALE at 200 mg/kg b.w. showed significant antidiabetic activity compared with standard Glibenclamide. Whereas dose at 100 mg/kg b.w. showed moderate activity. Conclusion: In conclusion, the M. oleifera exhibits more effectiveness against STZ-induced diabetes. The HAFE and HALF extracts exhibited significant anti-diabetic property and active components may be isolated and clinical studies is required for further evaluation. Because of the rich source of phytoconstients, nutritional elements will be helpful in processed food products as dietary supplements especially for malnutrition in children in the current era.

By the method of atomic emission spectrometry with inductively coupled plasma, the content of macro and microelements in the blood plasma of 35 practically healthy people living in the Northern region of Azerbaijan and in the Nizhny Novgorod region of the Russian Federation was studied as well as of 23 patients with pulmonary tuberculosis with different phases of the disease. The elemental homeostasis of the blood plasma did not significantly differ depending on the region of residence, except for the potassium level (by 1.3 times greater for Russians) and strontium (by 10 times higher among the inhabitants of the Northern region of Azerbaijan). In patients with focal pulmonary tuberculosis, there were no significant differences in the content of elements in the blood plasma. With pulmonary tuberculosis, accompanied by decomposition processes, the content of calcium, copper, zinc and iron in blood plasma significantly increases in comparison with healthy people. Analysis of the level of these macro- and microelements can be used to determine the transition of the early form of pulmonary tuberculosis to infiltrative and/or cavernous forms, in which the patient becomes epidemiologically dangerous to others.

Bredemeyera floribunda Wild (Polygalaceae), also known as pau-de-ovo is a medicinal plant used to treat snakebites, as tonic and fortifiers to treat fatigue and exhaustion. The aim of the present study was to document the knowledge of herbal sellers in the preparation of the so-called “B. floribunda fortifier” and to compare the plant root content with the recommended nutritional values and the permitted limit for medicinal plants. The study revealed that, unlike other regions of Brazil, in the Midwest region, the root of the plant is used as food to treat fatigue and exhaustion. The contents in B. floribunda root decreased in the following order: Ca > K > P > Na > Fe > Mg > Si > Mn > Zn > Cu. Daily intake of 30 grams of B. floribunda roots are considered as an excellent source of Cr, Cu, Mn and Se for people 19 to 50 years of age according to the RDA. In addition, Cu and Fe showed content above the established limit for medicinal plants stipulated by other countries. The root of the plant has low K, Mg, P, Na and Zn content. When the contents in roots of the plant are below the oral dose of reference, consumption of this plant can be considered safe and without risk to human health. On the other hand, concentration of elements such as Cu, Fe, Ni, Al, Cr and Se exceeding the allowable limit may cause serious health problems due to prolonged ingestion and large amounts consumed daily. The Brazilian legislation does not establish a permissible limit of macro- and micro-elements in medicinal plants;thus, the results presented in this study will contribute to the Brazilian public health policy on medicinal plants.

The article presents concentrations of 29 trace elements in different groups of basidiomycetes: saprotrophic, parasitic and symbiotic. The potential of using the concentration factor (Kc) is shown for the assessment of trace element accumulation by the fungi. The variations of trace element concentrations in different ecological and geochemical environment are presented. The data obtained in this research made it possible to mark out the group of trace elements that are mainly accumulated by fungi. This information helped to assess the correlation between the trace element concentrations in the mycothalluses of fungi and their mobile forms in the soil. The expected patterns of the trace element accumulation in fungi are described.
