JOURNAL OF ETHNOPHARMACOLOGY 2024; 320:117439. [PMID: 37981119 DOI: 10.1016/j.jep.2023.117439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/24/2023] [Accepted: 11/14/2023] [Indexed: 11/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Alchemilla L. (lady's mantle) comprises 1000 species, of which more than 300 have been characterized from Europe. Notably, as folk medicines, Alchemilla species have long been prescribed for the treatment of dysmenorrhea, pruritus vulvae, menopausal complaints, and related diseases in women. This review summarizes the traditional uses, highlights promising plant species, and focuses on phytochemical and biological studies to highlight future areas of research. AIM OF THE REVIEW This literature review aims to provide a comprehensive overview of Alchemilla species, covering their botany, traditional uses, phytochemistry, and biological and pharmacological activities, and to summarize the current research status to better understand the application value of Alchemilla plants in modern phytotherapy. MATERIALS AND METHODS The search strategy utilized the major thematic platforms Reaxys, Web of Science, Google Scholar, Scopus, ScienceDirect, PubMed, the USDA Plant Database and Kew Science (Royal Botanic Gardens) and was performed with the term Alchemilla. These platforms were systematically searched for articles published from 1960 to 2023. RESULTS AND DISCUSSION Alchemilla species, as members of the Rosaceae family, produce tannins, phenolic acids, flavonoids, anthocyanins, coumarins, triterpenes and violet compounds. Effort has been made with this comprehensive review of Alchemilla plants to highlight the recent developments and milestones achieved in modern phytochemistry and phytotherapy, underlaying a broad spectrum of the activities of these plants, such as antioxidant, anti-inflammatory, neuroprotective, antimicrobial, antiobesity, cardiovascular, anticancer, and wound healing effects. CONCLUSIONS An increasing number of studies on the plants in the Alchemilla genus have provided data about the main constituents and their importance in modern medicine. Both in vitro and in vivo studies have indicated that Alchemilla plants possess an extensive spectrum of biological activities. Regardless of the remarkable medical potential of Alchemilla extracts, clinical studies are limited and need to be performed to produce safer and less expensive plant-based drugs.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:7345-7357.

Abstract
This study investigates heavy metal contamination of commonly consumed medicinal herbs and human health risks to the Chinese population arising from the consumption of herbs that contain potentially harmful elements. Food safety standards for Chinese residents are becoming stricter, and much work in this field needs to be performed. This study examines Co, Ba, Fe, Cr, Mn, Ni, Zn, As, Cd, Pb, Cu, Be, Sb, and Bi concentrations in four regularly consumed Chinese herb species: Radix Paeoniae Alba (RPA), Radix Angelicae Dahuricae (RAD), Rhizoma Atractylodis Macrocephalae (RAM), and Radix Puerariae (RP). A pollution status examination and evaluation of heavy metals in RPA, RAD, RAM, and RP were performed. The human health risk assessment associated with the intake of potentially harmful elements in herbs was calculated in terms of the estimated daily intake (EDI), the target hazard quotient (THQ), the estimated hazard index (HI), and the lifetime cancer risk (CR). The mean single-factor pollution index (PI) showed that in the RPA, RAD, RAM, and RP samples, approximately 10.0%, 10.0%, 30.0%, and 10.0%, respectively, were polluted by Cd. The present study indicated that the pattern of consumption of the studied herbs in China does not seem to suggest an excessive health hazard associated with any of the toxic elements studied.

Abstract
For thousands of years, medicinal plants (MPs) have been one of the main sources of drugs worldwide. However, recently, heavy metal pollution has seriously affected the quality and safety of MPs. Consuming MPs polluted by heavy metals such as Pb, Hg, and Cu significantly threaten the health of consumers. To manage this situation, the levels of heavy metals in MPs must be controlled. In recent years, this field has attracted significant attention, but few researchers have systematically summarized various analytical methods. Therefore, it is necessary to investigate methods that can accurately and effectively detect the amount of heavy metals in MPs. Herein, some important analytical methods used to detect heavy metals in MPs and their applications have been introduced and summarized in detail. These include atomic absorption spectrometry, atomic fluorescence spectrometry, inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission spectrometry, X-ray fluorescence spectrometry, neutron activation analysis, and anodic stripping voltammetry. The characteristics of these methods were subsequently compared and analyzed. In addition, high-performance liquid chromatography, ultraviolet spectrophotometry, and disposable electrochemical sensors have also been used for heavy metal detection in MPs. To elucidate the systematic and comprehensive information, these methods have also been briefly introduced in this review.

Gray CW, McDowell RW, Condron LM, McLenaghen RD. Changes in soil cadmium concentrations with time following cessation of phosphorus fertilizer inputs. JOURNAL OF ENVIRONMENTAL QUALITY 2020; 49:1054-1061.

Abstract
Cadmium (Cd) can accumulate in soil from the application of phosphorus fertilizer. However, there is little information on what happens to soil Cd concentrations when Cd inputs stop. This study used soil and pasture samples collected from a long-term field trial to measure changes in Cd concentrations in soil for 22 yr after Cd inputs from fertilizer had stopped and assessed whether the application of nitrogen (N) (50 kg ha-1 yr-1 ) could increase plant uptake of Cd and reduce soil Cd concentrations. It was found that there was no significant change in total or labile soil Cd (1 M CaCl2 extractable) concentrations after Cd inputs stopped. The application of N did not significantly (P < .05) increase dry matter yield or increase Cd solubility. As a result, N did not enhance plant uptake of Cd. A mass balance that included Cd loss via plant uptake and Cd leaching confirmed they were insufficient to result in a detectable decrease in soil Cd concentration over the 22-yr interval of the trial. It appears that even an acid soil with low amounts of carbon (2.67%), iron/aluminum oxides, and clay can still strongly retain Cd, preventing Cd depletion from the soil, despite stopping Cd inputs and trying to enhance plant uptake of Cd from the application of N fertilizer.

Abstract
The relative ease with which cadmium (Cd) in agricultural soils can transfer to crop plants can pose a potential health risk to consumers. However, efforts to predict and mitigate these risks are often confounded by the various factors that influence metal accumulation in the edible plant parts. The aim of this work was to identify key drivers that determine Cd concentrations in spinach leaves, potato tubers, onion bulbs and wheat grain grown in commercial horticultural operations across New Zealand (NZ). Paired soil and plant samples (n = 147) were collected from farms across different NZ growing regions. Cadmium concentrations in the edible parts were measured and four different tests were used to examine the potential bioavailability of soil Cd: pseudo-total and porewater concentrations, 0.05 M Ca(NO3)2-extraction and diffusive gradients in thin-films (DGT). Information on a range of soil and climatic variables was also collected. The methods' ability to represent Cd concentrations in the plant parts was assessed through single and multiple regression analysis that considered the different variables and the farm locations. Soil Cd concentrations determined by the different tests were positively related to plant concentrations and there were clear regional differences between these relationships. The Ca(NO3)2 extraction predicted over 76% of the variability in Cd concentrations in onion bulbs and spinach leaves, while DGT and porewater Cd provided the best estimates for potato tubers and wheat grains, respectively, once regional differences were considered, along with certain environmental and soil variables. The results show that certain soil and environmental factors can be a key influence for determining Cd accumulation in the edible parts of some plants and that regional differences are important for modulating the extent to which this occurs. These effects should be considered when trying to mitigate the potential risks arising from Cd in agricultural soils.

Abstract
Paired soil and plant samples collected from the main commercial growing areas for onions (Allium cepa), lettuce (Lactuca sativa) and spinach (Spinacia olearacea) in New Zealand were used to assess the influence of plant and soil factors on cadmium (Cd) uptake in these crops. Differences in Cd concentration between eight lettuce sub-types were not consistent across sites, nor were differences in Cd concentrations in three crisphead cultivars assessed at two sites. Similarly, differences in Cd concentrations between four onion cultivars were inconsistent across sites. Mean lettuce Cd concentrations in eight lettuce varieties (range 0.005-0.034 mg∙kg-1 (fresh weight, FW) were markedly lower than those in baby leaf and bunching spinach, (range 0.005-0.19 mg∙kg-1 FW). Significant regional variation was observed in Cd concentrations in one onion cultivar (mean range 0.007-0.05 mg∙kg-1 FW). Soil Cd concentration, pH and region were statistically significant predictors of onion Cd concentration, explaining low (38% for soil Cd and pH) to moderate (50% for all three parameters) percentage of the variation. Soil Cd concentration and exchangeable magnesium or total carbon were statistically significant predictors of Cd concentration in baby leaf and bunching spinach, respectively, explaining a moderate percentage (49% and 42%) of the variation in Cd concentration. Increasing pH and soil carbon may assist in minimising Cd uptake in onion and bunching spinach, respectively. The low to moderate proportion of explained variation is partly attributable to the narrow range in some measured soil properties and indicates factors other than those assessed are influencing plant uptake. This highlights a challenge in using these relationships to develop risk-based soil guideline values to support compliance with food standards. Similarly, the inconsistency in Cd concentrations in different cultivars across sites highlights the need for multi-site assessments to confirm the low Cd accumulation status of different cultivars.

Abstract
Wheat ( L.) grain is a contributing source of dietary Cd in New Zealand, but despite this, there is a dearth of information on Cd concentrations in wheat and the factors that affect uptake. We measured Cd concentrations in 12 wheat cultivars grown in field sites across New Zealand and also assessed the soil, plant, and crop factors that have been reported to affect Cd uptake. We found there was a wide range in grain Cd concentrations (0.004 to 0.205 mg kg fresh weight [FW]). The overall mean concentration (0.066 mg kg FW) was below the maximum limit (ML) of 0.1 mg kg FW. Only 7% of grain samples across seven sites exceeded the ML. There were significant ( < 0.05) differences (2.5-fold) in Cd concentrations in wheat grain between cultivars. No strong significant relationships were found between soil properties and Cd concentrations in grain. Further, management factors affecting grain Cd concentrations were inconsistent. Given the lack of relationships between soils and management practices, the most effective way of limiting Cd uptake in wheat grain at sites where Cd exceeds MLs may be the use of low-Cd-accumulating cultivars. Further studies are required to explore specifically the influence of irrigation and effects of type and rate of fertilizer on Cd uptake in wheat, as well as to better understand the mechanisms of Cd uptake in wheat.
