Medicinal plants are, for a considerable part of the population, an important source of treatment for certain diseases. They contain essential nutrients for the human body such as magnesium, iron , and zinc. The present study shows the influence of the addition of As, Cd, Ni, Pb on mineral nutrients in different organs of Mentha piperita. The experiments were carried out in the laboratory for a period of three months (May-July). Mentha piperita plants were AsCd and AsCdNiPb exposed up to final concentrations corresponding to the soil intervention threshold according to Romanian Order no.756/1997 (25 mg/kg As, 5 mg/kg Cd, 150 mg/kg Ni and 100 mg/ kg Pb). Simultaneously with these experiments, a control experiment (M) was performed. To evaluate the effect of the addition of AsCd and AsCdNiPb on the accumulation and transfer of Ca, Cr, Cu, Mn, Mo, Fe and Zn, the transfer coefficient (TC), the translocation factor (TF), and the enrichment factor (EF) were calculated. A higher concentration of Ca, Cr, Cu, Fe, Mn, Mo, and Zn was observed especially in the mint root in the experiments in which AsCdNiPb was added compared to those in which only AsCd was added. The AsCdNiPb addition did not influence the translocation of micro and macronutrients from the root to the aerial (edible) parts of the plant. In the case of the AsCd, addition, the translocation of zinc from the root to the aerial parts (leaves and stem) of the plant was increased.

Today, Ozone as a disinfectant method, without putting on the harmful effects on human and plant products, it is alternative common methods for disinfection of plant material. The research as a factorial experiment was conducted on the basis of randomized complete block design with three replications and the effects of Ozone gas on decreasing the microbial load of some important medicinal plants include: Peppermint (Mentha piperita), Summer savory (Satureja hortensis), Indian valerian(Valeriana wallichii), Meliss (Melissa officinalis) and Iranian thyme (Zataria multiflora) were investigated. Medicinal plants leaves were treated with Ozone gas concentration 0.3, 0.6 and 0.9 ml/L at times of 10 and 30 then total count, coliform and mold and yeast of the samples were studied. The result showed that Ozone gas decreases microbial load of medicinal plants samples. But Ozone gas and Ozone gas in medicinal plants interaction effect had no effect on essential oil content. The lowest and the highest of microbial load were detected in samples treated with concentration of 0.9 ml/L of Ozone gas and control respectively. The highest and the lowest of microbial load were observed in Iranian thyme and Indian valerian respectively. Also result showed that Ozone gas treatment for 30 min had the greatest of effect in reducing the microbial load and 0.9 ml/L Ozone gas concentration had the lowest of microbial load. Results of this survey reflect that the use of Ozone as a method of disinfection for medicinal plants is a decontamination.

AbstractRecent focus is on analysis of biological activities of extracts from plant species. Zygophyllaceae is exceedingly important angiosperm family with many taxa being used in folk medicines widely dispersed in arid and semi-arid zones of Balochistan, Pakistan. Only a small proportion of them have been scientifically analyzed and many species are nearly facing extinction. Therefore present investigation explores the biochemical and bioactive potential of fourteen folk medicinal plants usually used for treatments of different ailments. Fresh aerial parts of nine taxa and two fruit samples were collected from plants growing in arid and semi-arid zones of Balochistan and analyzed for enzymatic, non-enzymatic and other biochemical activities. Higher phytochemical activities were detected in the aerial parts. Superoxide dismutase was detected maximum in Fagonia indica, (184.7±5.17 units/g), ascorbate peroxidase in Tribulus longipetalus subsp. longipetalus (947.5±12.5 Units/g), catalase and peroxidase was higher in Peganum harmala (555.0±5.0 and 2597.8±0.4 units/g respectively). Maximum esterase and alpha amylase activity was found in Zygophyllum fabago (14.3±0.44 and 140±18.8 mg/g respectively). Flavonoid content was high in T. longipetalus subsp. longipetalus (666.1±49 μg/ml). The highest total phenolic content and tannin was revealed in F. olivieri (72125±425 and 37050±1900 μM/g. respectively). Highest value of ascorbic acid was depicted in F. bruguieri var. rechingeri (448±1.5 μg/g). Total soluble Proteins and reducing sugars were detected higher in P. harmala (372.3±54 and 5.9±0.1 mg/g respectively). Maximum total antioxidant capacity (TAC) was depicted in Z. simplex (16.9±0.01 μM/g). Pigment analysis exhibited the high value of lycopene and total carotenoids in T. terrestris (7.44±0.2 and 35.5±0.0 mg/g respectively). Chlorophyll a, b and total chlorophyll content was found maximum in T. longipetalus subsp. pterophorus (549.1±9.9, 154.3±10 and 703.4±20.2 ug/g respectively). All taxa exhibited anti-inflammatory activity as well as anti-diabetic inhibitory potential. Seed extracts of Zygophyllum eurypterum (96%) exhibited highest inhibitory potential, along with twelve other taxa of Zygophyllaceae indicated (96-76%) activity when compared with the standard drug diclofenac sodium (79%). Seeds of T. longipetalus subsp. longipetalus (85%) exhibited the highest anti-diabetic activity; other eleven taxa also exhibited inhibitory activity of α-amylase ranging from (85-69%) compared with Metformin (67%) standard drug. Phytochemical screening revealed that selected taxa proved to be the potential source of natural antioxidants and could further be explored for in-vivo studies and utilized in pharmaceutical industries as potent therapeutic agents validating their ethno-pharmacological uses.

The purpose of our study was to bring elements of knowledge on the anticancer and antibacterial effects of two plants, widely used in Moroccan traditional pharmacopeia. These plants are: Marrubium vulgare and Euphorbia resinifera. The aerial parts of each plant were extracted successively with Hexane, Dichloromethane, and finally with methanol. The MTT-based method was applied to evaluate the cytotoxicity of the cancer cells: animal cells BSR and Vero and human cell RD. We evidenced an anticancer activity of the extract of the Marrubium vulgare and the dichloromethane extract of Euphorbia resinifera against the studied cells. The antibacterial activity was evaluated for three species of Rhodococcus: Rhodococcus equi, and strains GK1, GK3, grown in a liquid medium, or this medium solidified with agar. In the last test, the method is based on substance diffusion from well throughout the solid medium. The obtained profiles showed that the growth of bacteria is strongly inhibited by the extracts of Marrubium vulgare. However, the extracts of Euphorbia resinifera had no significant effect on bacterial growth. The chemical analysis of the raw extracts of Marrubium vulgare and Euphorbia resinifera by GC-MS analysis showed the presence of several major chemical compounds, mainly: octadecane, 2,6,10,15-tetramethylheptadecane, 2,6,10-trimethyltetradecane, linoleic acid, and deisopropylatrazine. Our observations an encouraging for deepening the studies of the extracts, in order to target better the active molecules, isolate them and to determine their mechanisms of action. The suggested studies would result in the much better valorization of these two medicinal plants.

The micronutrients iron (Fe) and zinc (Zn) are not only essential for plant survival and proliferation but are crucial for human health. Increasing Fe and Zn levels in edible parts of plants, known as biofortification, is seen a sustainable approach to alleviate micronutrient deficiency in humans. Wheat, as one of the leading staple foods worldwide, is recognized as a prioritized choice for Fe and Zn biofortification. However, to date, limited molecular and physiological mechanisms have been elucidated for Fe and Zn homeostasis in wheat. The expanding molecular understanding of Fe and Zn homeostasis in model plants is providing invaluable resources to biofortify wheat. Recent advancements in NGS (next generation sequencing) technologies coupled with improved wheat genome assembly and high-throughput genotyping platforms have initiated a revolution in resources and approaches for wheat genetic investigations and breeding. Here, we summarize molecular processes and genes involved in Fe and Zn homeostasis in the model plants Arabidopsis and rice, identify their orthologs in the wheat genome, and relate them to known wheat Fe/Zn QTL (quantitative trait locus/loci) based on physical positions. The current study provides the first inventory of the genes regulating grain Fe and Zn homeostasis in wheat, which will benefit gene discovery and breeding, and thereby accelerate the release of Fe- and Zn-enriched wheats.

Background: Anthropogenic activities release metals into the environment that could be absorbed by plants and assimilate into herbal medicines. Objective: This study sought to correlate the outcome of anthropogenic activities that release metals into the environment with levels of metals in medicinal plants using the leaves of Moringa oleifera Lam. (M. oleifera)as a case study. Methods: Leaves of M. oleifera and soil around sampled plants were collected from three locations in the Accra Metropolis: a commercial area, an area with dense vehicular traffic, and a quasi-natural habitat. Samples were analyzed with Energy Dispersive X-ray Fluorescence (ED-XRF) spectroscopy for the presence and levels of arsenic (As), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), vanadium (V) and zinc (Zn). Statistical analyses were performed and the correlation between metal concentrations in leaves and soil was assessed using Spearman’s correlation coefficient. Results: Levels of metals in the leaves and soil samples varied with the site of sample collection. Levels of metals in leaves were significantly lower than permissible limits (p< 0.05) in herbal medicines. Translocation factor (TF) estimates indicated that the M. oleifera leaves exclude the metals under investigation irrespective of the site of collection. However, the TF > 1 in the case of Zn from the quasi-natural habitat signifying bioaccumulation in the leaves. Except forCo, the total concentration of each metal in the soil was not correlated with its concentration in the leaves. Conclusion: The concentration of sampled metals in the leaves and soil varied with the site of sampling and potentially with the anthropogenic activities that release metals into that environment.

Abstract In recent years, a series of environmental and ecological problems have occurred due to enhanced anthropogenic disturbances for precious minerals mining. Traditional medicines have become an important pillar in national homeopathic treatment system especially in mountainous environment of developing countries. The current study investigates the level of potentially toxic elements ( PTEs ) contamination in degraded mining soil and medicinal plants along the mafic-ultramafic rocks in the Kohistan region. Soil samples and medicinal plant species were collected from the degraded mining area and were screened for PTEs (Pb, Cr, Ni, Mn, Zn, and Cd) using atomic absorption spectrometry. Various pollution indices were used for PTEs such as contamination factor (CF), pollution load index (PLI) and translocation factor (TF) in degraded mining soil and medicinal plants. The mean concentration of PTEs found in soil were in order of Mn>Ni>Cr >Pb>Zn>Cd, while in medicinal plants were Pb>Cr>Mn>Ni>Zn>Cd. Highest bioaccumulation was observed in Ajuga bracteosa (Cr=349 mg kg –1 ), Phlomis bracteosa (Pb=335 mg kg –1 ), Chenopodium ambrosioides (Mn = 304.3 mg kg –1 ), Isatis costata (Ni=169 mg kg –1 ), Ajuga parviflora (Zn = 38.4 mg kg –1 ) and Salvia moorcoftiana (Cd=11 mg kg –1 ). Furthermore, the concentrations of PTEs were significantly higher ( p <0.001) in degraded mining soil and medicinal plants than the reference site, which may be attributed to the mining and open dumping of mining wastes. The present study revealed that chromite mining and open dumping of mining wastes can cause serious environmental problem in the study area. Furthermore, medicinal plants grown in degraded mining soil may pose risk to the local inhabitants as most of the people consume these plants for various health problems.
