Abstract
Traditional Chinese medicine (TCM) that is used worldwide possesses the satisfactory function of disease prevention, treatment and health care, and this natural medicine seems to be favored due to its low side effects. Endocrine disrupting chemicals (EDCs), which exist in all aspects of our lives, may interfere with the synthesis, action and metabolism of human sex steroid hormones, resulting in the development and fertility problems as well as obesity and the disturbance of energy homeostasis. From planting to processing, TCM may be polluted by various EDCs. Many studies pay attention to this problem, but there are still few reviews on the residues and toxicity risks of EDCs in TCM. In this paper, researches related to EDCs in TCM were screened. The possible contamination sources of TCM from planting to processing and its toxic effects were introduced. Moreover, the residues of metals, pesticides and other EDCs in TCM as well as the health risks of human exposure to EDCs through ingestion of TCM materials were reviewed.

Abstract
The changes of microbial communities of rhizospheric soil in different ages are speculated to cause soil-borne diseases and replanting problem in American ginseng (Panax quinquefolius L.) cultivation. This study analyzed the physicochemical properties and microbial communities of rhizospheric soil during the planting of American ginseng in the Wendeng area of Weihai, China. The water content and organic matter content of American ginseng rhizospheric soil decreased year by year. A decline in the diversity of bacteria and fungi was observed in the rhizospheric soils planting American ginseng compared with the traditional crop wheat in the control group. During the later planting stage, the abundances of Proteobacteria, Actinobacteria, and Basidiomycota were lower, whereas that of Acidobacteria, Firmicutes, and Mucoromycota were higher. Through the correlation analysis between environmental factors and microbial community, it was found that the content of soil phosphorus was significantly positively correlated with the root rot pathogen Fusarium. The results of functional prediction showed that the decrease of secondary metabolite synthesis of rhizospheric soil bacteria and the increase of plant pathogenic fungi may be the important reasons for the increase of diseases in the later stage of American ginseng planting. This study revealed the evolution of rhizosphere microbial community and function in the process of American ginseng planting, which is valuable for planting management.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2022; 102:1415-1421. [PMID: 34375005 DOI: 10.1002/jsfa.11474] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 07/09/2021] [Accepted: 08/10/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Carbendazim and epoxiconazole are widely applied to control anthracnose and sand bark fungal diseases in citrus. The residues of these two fungicides in citrus and their potential risk to consumers have generated much public concern. We therefore sought to investigate the dissipation, residue, and dietary risk assessment of carbendazim and epoxiconazole in citrus. RESULTS The dissipation kinetics and residue levels of carbendazim and epoxiconazole in citrus under field conditions were measured using dispersive solid-phase extraction and ultra-high-performance liquid chromatography-tandem mass spectrometry. The citrus samples were extracted with acetonitrile and purified by primary secondary amine sorbent. The mean recoveries of carbendazim and epoxiconazole ranged from 86.2 to 105.6% and relative standard deviations were ≤9.8%. The half-lives of carbendazim and epoxiconazole in whole citrus ranged from 2.0 to 18.0 days. Hazard quotient (HQ) and risk quotient (RQ) models were applied to whole citrus for dietary exposure risk assessment based on the terminal residue test. Hazard quotients ranged from 0.066 to 0.134% and RQs from 18.48 to 82.12%. CONCLUSION Carbendazim and epoxiconazole in citrus degraded rapidly following first-order kinetics models. The dietary risk of exposure to both carbendazim and epoxiconazole through citrus, based on HQ and RQ, was acceptable for human consumption. This study indicates scientifically validated maximum residue limits in citrus, which are currently lacking for epoxiconazole in China. © 2021 Society of Chemical Industry.

Abstract
As a widely used fungicide, the environmental fate of carbendazim and its residues in agricultural products have caused great concern. However, its effects on soil microbial communities are largely unknown. Herein, we used high-throughput sequencing to reveal the effects of high and low dose of carbendazim and its degrading strain, Rhodococcus qingshengii strain djl-6, on the composition, diversity, and interrelationship of soil bacterial and fungal communities in short- and medium-term under laboratory conditions. The results showed that carbendazim exhibited an increased negative impact on bacterial communities and reduced the proportion of dominant fungal phylum Ascomycota during a 14-day incubation period. Only the impacts of low-dose carbendazim (2 mg·kg-1 dry soil) on fungal community were weakened. Network analysis showed that carbendazim increased the connectivity and modularity of microbial co-occurrence networks. Strain djl-6 exhibited good potential for bioremediation of carbendazim-contaminated soils. Moreover, it driven the assembly of potential carbendazim-degrading consortia from indigenous microbial communities; and members of the genera Arthrobacter, Bacillus, Brevundimonas, Lysinibacillus, Massilia, Mycobacterium, Paenibacillus, and Pseudarthrobacter might be participated in the degradation of carbendazim. Taken together, our study provides a relatively comprehensive understanding of the effects of carbendazim and its degrading strain djl-6 on soil microbial communities.

Abstract
This study aims to encapsulate the fungicide carbendazim using a biodegradable polymer (pectin). First, we have obtained calcium pectinate beads (CPG-Carb) by ionotropic gelation using calcium ions as a crosslinking agent. These beads were then coated with silica starting from tetraethoxysilane (TEOS), by a sol-gel process to form hybrid beads (CPG-Carb-SG). The morphology, composition and structure of both beads were characterized and the controlled release assays of the fungicide were studied in both water and soil columns. The encapsulation efficiency for CPG-Carb was slightly higher (75%) compared to CPG-Carb-SG (67%) due to carbendazim loss during the impregnation and condensation steps. The release rate in water and soil columns was about 4 times lower for CPG-Carb-SG than CPG-Carb demonstrating the efficiency of the silica coating to delay the release of carbendazim. Moreover, the release of CPG-Carb-SG is due to the erosion of the silica layer during the first two weeks. After this period, the silica layer was degraded, and the release is then controlled by the swelling of the organic part of the bead as observed for CPG-Carb. Finally, the biodegradability of the pectin, and the release profile make such systems promising candidates for sustained and economical pesticide delivery systems.

Abstract
Owing to a dramatic increase in average life expectancy, most countries in the world are rapidly entering an aging society. Therefore, extending health span with pharmacological agents targeting aging-related pathological changes, are now in the spotlight of gerosciences. Panax notoginseng (Burk.) F. H. Chen, a species of the genus Panax, has been called the "Miracle Root for the Preservation of Life," and has long been used as a Chinese herb with magical medicinal value. Panax notoginseng has been extensively employed in China to treat microcirculatory disturbances, inflammation, trauma, internal and external bleeding due to injury, and as a tonic. In recent years, with the deepening of the research pharmacologically, many new functions have been discovered. This review will introduce its pharmacological function on lifespan extension, anti-vascular aging, anti-brain aging, and anti-cancer properties, aiming to lay the ground for fully elucidating the potential mechanisms of Panax notoginseng's anti-aging effect to promote its clinical application.

Abstract
Synthesis and controlled release study of polymeric nanoformulation of carbendazim (2-benzimidazole carbamic acid methyl ester) using chitosan and pectin is reported in this article. The formulation was subjected to morphological, physiological, in vitro fungicide release and bio-efficacy evaluation studies. The average size of nanoparticles was found to be in the range of 70-90 nm as confirmed by transmission electron microscopy. The in vitro fungicide release of nanoformulated carbendazim was compared with pure carbendazim at different pH values. The results confirmed sustained release of nanoformulated carbendazim. The bio-efficacy evaluation of the carbendazim nanoformulation was carried out against Fusarium oxysporum and Aspergillus parasiticus. The nanoformulation showed 100 % inhibition of test fungi at both concentrations (0.5 and 1.0 ppm) while pure carbendazim showed 80 ± 0 % and 97.2 ± 1.1 % inhibition at 0.5 and 1.0 ppm concentration respectively against Fusarium oxysporum and 86.0 ± 0.6 % inhibition and 100.0 % inhibition at 0.5 and 1.0 ppm concentration respectively against Aspergillus parasiticus. The commercial formulation (WP 50) showed 42 % and 58.0 ± 0.1 % inhibition at 0.5 and 1 ppm concentration respectively against Aspergillus parasiticus and 50.5 ± 0.7 % and 70.0 ± 0 % inhibition at 0.5 and 1.0 ppm concentrations respectively against Fusarium oxysporum. Phytotoxicity evaluation of nanoformulated fungicide confirmed that the nanoformulated carbendazim is safer for germination and root growth of the seeds of Cucumis sativa, Zea mays, and Lycopersicum esculantum.

Abstract
Asian ginseng, American ginseng, and notoginseng are three major species in the ginseng family. Notoginseng is a Chinese herbal medicine with a long history of use in many Oriental countries. This botanical has a distinct ginsenoside profile compared to other ginseng herbs. As a saponin-rich plant, notoginseng could be a good candidate for cancer chemoprevention. However, to date, only relatively limited anticancer studies have been conducted on notoginseng. In this paper, after reviewing its anticancer data, phytochemical isolation and analysis of notoginseng is presented in comparison with Asian ginseng and American ginseng. Over 80 dammarane saponins have been isolated and elucidated from different plant parts of notoginseng, most of them belonging to protopanaxadiol or protopanaxatriol groups. The role of the enteric microbiome in mediating notoginseng metabolism, bioavailability, and pharmacological actions are discussed. Emphasis has been placed on the identification and isolation of enteric microbiome-generated notoginseng metabolites. Future investigations should provide key insights into notoginseng's bioactive metabolites as clinically valuable anticancer compounds.

Abstract
Food safety is a global concern due to the increased use of pesticides in agriculture. In grapes, carbendazim is one of the frequently detected fungicides. However, it is amenable to biodegradation. In this study, we aimed to assess the degradation of carbendazim by four Bacillus subtilis strains, which had earlier shown potential for biocontrol of grape diseases. In liquid medium, each of the four strains, namely, DR-39, CS-126, TL-171, and TS-204, could utilize carbendazim as the sole carbon source. The half-life was minimized from 8.4 days in the uninoculated spiked control to 4.0-6.2 days by the four strains. In Thompson Seedless sprayed with carbendazim at 1.0 g L(-1), the residue on grape berries in control was 0.44 mg kg(-1) after 25 days of application, whereas in grapes treated with the four B. subtilis strains, the residues had decreased to 0.02 mg kg(-1). The degradation kinetics showed low half-lives of 3.1 to 5.2 days in treated grapes as compared to 8.8 days in control. In inoculated soils, the half-lives were 5.9 to 7.6 days in autoclaved and 6.5 to 7.2 days in nonautoclaved soils as compared to 8.2 and 8.0 days in respective controls. The growth dynamics of these strains in all the three matrices was not affected by presence of carbendazim. Bacillus strains TS-204 and TL-171 showed higher degradation rate than the other two strains in all the three matrices and show promise for in situ biodegradation of carbendazim.
