“…For the experiment, mycotoxins were obtained in the Department of toxicology of the FSBI "FCTRB-VNIVI". The study of the adsorption capacity in vitro, put a technique that takes into account the detection of secondary metabolites of micromycetes [19,20,21]. In the experiments, preparations divided into the following groups were used: in the first group, a Microbond preparation was used, a feed additive for the adsorption of mycotoxins and heavy metals; in the second group, bentonite clay from the Apastovsky deposit of the Republic of Tatarstan, heat-treated at 500 0 C; in the third group, bentonite from the Tarn-Varsky deposit of the Republic of Tatarstan was used; in the fourth group, bentonite clay from the Apastovsky deposit of the Republic of Tatarstan was used; the fifth group was the zeolite sorbent from the Tatarsko-Shatrashansky deposit of the Republic of Tatarstan; the sixth group was the Biosorb bacterial sorbent produced by the Federal State Budgetary Institution "FCTRB-VNIVI"; the seventh group was the zeolite from the Main deposit of the Ulyanovsk region; The eighth group of Zoocarb is a carbon sorbent developed at the NTU "Engineering and Technological Institute of Carbon Black".…”

This paper presents research on the study of the adsorption properties of sorbents of mineral and organic origin. From the research results, it was seen that the maximum adsorption properties for zearalenone at room temperature of 19-21 ° C and pH 7 were shown by sorbents: bentonite of the Biklyansky deposits 34.7%, bentonite of The biklyansky burned 25.3%, bentonite of the tarn-Varna deposits 31.4% Mycosorb 65.7%, Phytosorb 57.5%, zeolite 27.3%, Zookarb 21.2% showed the lowest sorption capacity for zearalenone. In relation to the T-2 toxin, the adsorption properties of sorbents at a temperature of 19-21 ° C and pH 7 showed: Phytosorb 57.5%, bentonite of the Biklyansky deposits 51.7%, bentonite of the tarn-Varna deposits 57.4%, Mycosorb 55.7%, Zoocarb 43.8%, zeolite 36.2%, bentonite of the biklyansky fired 31.4%. According to the results of research, it can be concluded that when the average temperature increases from 20-21 ° C to 38-39 ° C, sorbents significantly increase the adsorption of toxins from 50-70% by such sorbents as phytosorb, Mycosorb, bentonite of the Biklyansky Deposit.

Medicinal plants are natural sources to unravel novel bioactive compounds to satisfy human pharmacological potentials. The world’s demand for herbal medicines is increasing year by year; however, large-scale production of medicinal plants and their derivatives is still limited. The rapid development of modern technology has stimulated multi-omics research in medicinal plants, leading to a series of breakthroughs on key genes, metabolites, enzymes involved in biosynthesis and regulation of active compounds. Here, we summarize the latest research progress on the molecular intricacy of medicinal plants, including the comparison of genomics to demonstrate variation and evolution among species, the application of transcriptomics, proteomics and metabolomics to explore dynamic changes of molecular compounds, and the utilization of potential resources for natural drug discovery. These multi-omics research provide the theoretical basis for environmental adaptation of medicinal plants and allow us to understand the chemical diversity and composition of bioactive compounds. Many medicinal herbs’ phytochemical constituents and their potential health benefits are not fully explored. Given their large diversity and global distribution as well as the impacts of growth duration and environmental factors on bioactive phytochemicals in medicinal plants, it is crucial to emphasize the research needs of using multi-omics technologies to address basic and applied problems in medicinal plants to aid in developing new and improved medicinal plant resources and discovering novel medicinal ingredients.

“…Phillips et al synthesized a highly active sodium bentonite clay with enhanced AFB 1 sorption efficacy compared with bentonite clay and other clays [ 9 ]. Karmanov et al studied the performance of adsorption-desorption of aflatoxin B2 (AFB 2 ) using lignins obtained from several cultivated and medicinal plants in an in vitro simulated gastrointestinal tract environment; lignins from ledum and jerusalem artichoke exhibited the highest AFB 2 adsorption capacity, and the chemisorption mechanisms played the most leading role [ 10 ]. However, the adsorption capacity gradually decreases as the adsorbents are saturated with the adsorbed AFs.…”

Aflatoxin B1 (AFB1) is a highly toxic mycotoxin produced by aspergillus species under specific conditions as secondary metabolites. In this study, types of PCL (Polycaprolactone) membranes anchored (or not) to g-C3N4/CQDs composites were prepared using electrospinning technology with (or without) the following surface modification treatment to remove AFB1. These membranes and g-C3N4/CQDs composites were characterized by SEM, TEM, UV-vis, XRD, XPS and FTIR to analyze their physical and chemical properties. Among them, the modified PCL-g-C3N4/CQDs electrospun membranes exhibited an excellent ability to degrade AFB1 via synergistic effects of adsorption and photocatalysis, and the degradation rate of 0.5 μg/mL AFB1 solution was observed to be up to 96.88% in 30 min under visible light irradiation. Moreover, the modified PCL-g-C3N4/CQDs electrospun membranes could be removed directly after the reaction process without centrifugal or magnetic separation, and the regeneration was a green approach synchronized with the reaction under visible light avoiding physical or chemical treatment. The mechanism of adsorption by electrostatic attraction and hydrogen bonding interaction was revealed and the mechanism of photodegradation of AFB1 was also proposed based on active species trapping experiments. This study illuminated the highly synergic adsorption and photocatalytic AFB1 removal efficiency without side effects from the modified PCL-g-C3N4/CQDs electrospun membranes, thereby offering a continual and green solution to AFB1 removal in practical application.
