Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The burden of disease caused by mental and neurological disorders is increasing globally, to a disproportionate degree in Latin America. In contrast to the many psychoactive plants with a use history in Mesoamerican cultures, the translation to the wider population of knowledge around numerous botanicals used contemporarily by indigenous Mesoamerican societies to treat psychological and neurological disorders did not receive the same attention. MATERIAL AND METHODS We used the previously published Mesoamerican Medicinal Plant Database to extract species and associated botanical drugs used as treatments for illnesses associated with the nervous system by Mesoamerican cultures in Belize, Guatemala, and Mexico. With the critical use of published pharmacological literature, the cross-culturally most salient genera are systematically reviewed. RESULTS From 2188 plant taxa contained in the database 1324 are used as treatments for illnesses associated with the nervous system. The ethnomedical data was critically confronted with the available biomedical literature for the 58 cross-culturally most salient genera. For a considerable proportion of the frequently used taxa, preclinical data are available, mostly validating ethnomedicinal uses. CONCLUSION This quantitative approach facilitates the prioritization of taxa for future pre-clinical, clinical and treatment outcome studies and gives patients, practitioners, and legislators a fundamental framework of evidence, on which to base decisions regarding phytomedicines.

[PMID: 32998023 DOI: 10.1016/j.jep.2020.113420] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 09/07/2020] [Accepted: 09/23/2020] [Indexed: 05/29/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia annua L. is a traditional Chinese medicine used for the treatment of malaria, jaundice and intense fever. AIM OF THE STUDY The aim of the present study was to investigate the phytochemicals, antioxidants, antimicrobial and synergistic potential of methanolic and petroleum ether extracts of A. annua against bacterial and fungal pathogens. METHOD Antioxidant activity of different concentrations of methanolic and petroleum ether extracts of A. annua was determined by DPPH free radical scavenging assay. Antimicrobial activity was determined by agar well diffusion, whereas MIC and synergistic activity was done by broth dilution method.TLC and GC-MS were done to identify active phytocompounds present in methanolic and petroleum ether extracts. RESULTS Methanolic extract of A. annua showed higher antioxidant potential (IC50 37 0.75 ± 0.34 μg ml-1) as compared to petroleum ether extract. In antimicrobial analysis, methanolic and petroleum ether extracts of A. annua produced potent inhibitory activity against Candida strains as compared to bacterial strains. Methanolic and petroleum ether extracts of A. annua produced synergistic potential with decrease in MIC from 4 to 264 folds against bacterial (S. aureus and E. coli) and Candida strains in combination with antibacterial and antifungal antibiotics. Sub fraction I of methanolic and petroleum ether extracts was isolated through silica TLC and showed 10-fold more antimicrobial activity as compared to crude extract. GC-MS analysis of sub-fraction I of A. annua revealed 13 major phytocompounds with area more than 1%. Interestingly, 2-Propenoic acid and ridecyl ester (25.88%) were the major phytocompounds. CONCLUSION Phytocompounds of A. annua can be used as bioenhancer of antibacterial and antifungal agents to control drug resistance.

Abstract
Sleep is an essential component of physical and emotional well-being, and lack, or disruption, of sleep due to insomnia is a highly prevalent problem. The interest in complementary and alternative medicines for treating or preventing insomnia has increased recently. Centuries-old herbal treatments, popular for their safety and effectiveness, include valerian, passionflower, lemon balm, lavender, and Californian poppy. These herbal medicines have been shown to reduce sleep latency and increase subjective and objective measures of sleep quality. Research into their molecular components revealed that their sedative and sleep-promoting properties rely on interactions with various neurotransmitter systems in the brain. Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that plays a major role in controlling different vigilance states. GABA receptors are the targets of many pharmacological treatments for insomnia, such as benzodiazepines. Here, we perform a systematic analysis of studies assessing the mechanisms of action of various herbal medicines on different subtypes of GABA receptors in the context of sleep control. Currently available evidence suggests that herbal extracts may exert some of their hypnotic and anxiolytic activity through interacting with GABA receptors and modulating GABAergic signaling in the brain, but their mechanism of action in the treatment of insomnia is not completely understood.

Abstract
Soil physicochemical properties and microbial diversity both play equally important roles in tobacco cultivation. However, the relationship between these factors remains unclear. In this study, we investigated their correlations through the whole tobacco growth period, including the pretransplanting (YX-p), root extending (R), flourishing (F), and mature (M) stages in the Yuxi region of the Yunnan-Guizhou Plateau by measuring physicochemical properties and conducting 16S/18S rRNA analysis. The analysis demonstrated that the microbial community richness and diversity continuously changed along with the growth course of the tobacco. Multiple environmental factors showed a certain correlation with the diversity of microbial communities. Some bacteria could accumulate nitrogen during the growth stages, and the diversity of the bacterial community also increased when the content of organic matter rose. In addition, the water content and available K also influenced the diversity of the microbial community. The dynamic changes in soil physicochemical properties and enzyme activities gave rise to differences in the microbial community composition and structure, all of which affected the growth of tobacco. This study revealed the time-course relationship between environmental factors and microbial diversity in tobacco soil. An understanding of this relationship provides guidance for research on the interaction system of plants, soil and microbes and on improving plant yield and quality.

Abstract
The anti-malarial drug artemisinin is extracted from the leaves of Artemisia annua L. Due to toxicity to some microorganisms, the release of artemisinin from this medicinal plant in commercial cultivation might produce a potential risk for phosphorus (P) solubilizing bacteria (PSB). Therefore, the growth, P mobilization, and proton and organic acid efflux by two PSB isolates, Bacillus subtilis and Pseudomonas fluorescens, obtained from the soil without growing A. annua L. in history in the region for growing A. annua L., Chongqing, China, were studied through soil and solution incubations with different nominal concentrations of artemisinin (0, 2.5, 5.0, and 10.0 mg/kg or mg/L). Addition of artemisinin into soil and culture solutions decreased significantly the number of PSB except P. fluorescens at a low artemisinin concentration (2.5 mg/L) in culture solution which remained unchanged in comparison with the control (without artemisinin). This suggests high artemisinin inhibited the cell division or led to the death of PSB, and the different species responded differently to artemisinin. Compared with original soil, PSB inoculation significantly increased Olsen P, whilst the addition of artemisinin decreased this P form in soil. There was a positive correlation between the number of PSB and Olsen P content in soils (r2 = 0.824, n = 8), indicating the involvement of PSB in P mobilization of insoluble minerals. Oxalate and acetate were commonly found in the bacterial culture solutions, which accounted for 73.6-84.4% of all organic acids in the culture medium without artemisinin. Malate was detected in the culture solution of B. subtilis, and citrate and succinate in P. fluorescens. The percentage of tricalcium phosphate solubilization (PTPS) positively correlated to the concentrations of protons and all organic acids (r2proton=0.901, n=8, P<0.01; r2organic acids=0.923, n=8, P<0.01). The concentrations of protons, organic acids and soluble inorganic P in culture solutions, and PTPS were decreased simultaneously as nominal artemisinin concentrations increased. For these decreases it implies the metabolic inhibition and the death of PSB caused by artemisinin could be the main reasons for the less efflux of protons and organic acids, presumably resulting in the decreased ability of PSB to mobilize inorganic P. Therefore, artemisinin released from A. annua L. in commercial and continual cultivation could adversely affect the community structure and inorganic P mobilization of PSB in soils.

Abstract
The Artemisia group of plants has long been used as a traditional remedy for various conditions. The present study assessed the sleep-promoting (sedative-hypnotic) effects of Artemisia capillaris Thunberg (A. capillaris), and elucidated a possible mechanism behind its effect. ICR mice were given A. capillaris extract (oral) at different dosages (50, 100, 200, 300, or 400 mg/kg), distilled water (oral; control), or diazepam (intraperitoneal; reference drug). One hour after administration, locomotion (open-field test) and motor coordination (rota-rod test) were assessed. The extract's effect on pentobarbital-induced sleep was also evaluated. Additionally, electroencephalographic (EEG) recordings were measured in rats. To evaluate a possible mechanism behind its effects, changes in chloride ( Cl -) ion influx were measured in human neuroblastoma cells. As compared to the control group, mice treated with A. capillaris demonstrated significantly decreased locomotor activity and impaired motor balance and coordination. The extract also shortened the onset and lengthened the duration of sleep induced by pentobarbital sodium. These effects were comparable to that induced by diazepam. Furthermore, A. capillaris-treated rats showed increased delta and decreased alpha EEG waves; an electroencephalographic pattern indicative of relaxation or sedation. In neuroblastoma cells, the extract dose-dependently increased Cl - ion influx, which was blocked by co-administration of bicuculline, a GABAA receptor competitive antagonist, suggesting that its effects are mediated through the GABAA receptor– Cl - ion channel complex. Altogether, the results of the present study demonstrate that A. capillaris possesses potent sedative-hypnotic effects, which are probably mediated through potentiation of the GABAA receptor– Cl - ion channel complex.

Abstract
Background: Artemisiae annuae herba (AAH) has been traditionally used as a drug for the treatment of malaria, heat stroke, bacterial infection, and fever in East-Asia. Although AAH has been used for the treatment of inflammation-related symptoms, the underlying mechanism of antiinflammatory activity of AAH is still unknown. Objective: We investigated whether AAH have an inhibitory effect on the production of pro-inflammatory mediators in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Materials and Methods: The investigation was forced on the inhibitory effect of AAH on the production of tumor necrosis factor (TNF)-α, interleukin (IL)-6, nitric oxide (NO), and inducible NO synthase (iNOS) in macrophages. Furthermore, we examined the effect of AAH on the activation of nuclear factor kappa B (NF-κB) and mitogen-activated protein kinases (MAPKs) pathways. Results: We found that AAH suppresses NO production and TNF-α, IL-6, and iNOS gene expression. Moreover, AAH inhibited the nuclear translocation of p65 and IκBα degradation in NF-κB pathway and decreased the extracellular signal-regulated kinase, p38, c-Jun NH2-terminal kinase phosphorylation in MAPK signaling pathway. Conclusions: Consequently, these results indicate that AAH contains antiinflammatory activity and this effect is derived from the repression on the activation of NF-κB and MAPKs pathways. We first demonstrated that antiinflammatory effect of AAH and its underlying mechanism in macrophage cells.
