Preparation and characterization of chitosan nanoparticles with extracts of Rheum ribes, evaluation of biological activities of extracts and extract loaded nanoparticles

The biological activities of different parts of the Rheum ribes plant were evaluated comparatively. Extracts showing strong biological activity were identified and it was determined which of the extract-loaded nanoparticles showed stronger activity. Cytotoxic activity of R. ribes extracts was calculated on glial (C6) and fibroblast (NIH 3T3) cells using XTT assay. Spectrophotometry was used to evaluate the impact of these compounds on the enzyme activities of human carbonic anhydrase I and II (hCA I and hCA II). The findings showed that chitosan NPs with extracts loaded on them have a lower IC50 value and more cytotoxic activity in C6 cells than chitosan NPs with only extracts. R. ribes young shoots ultrasonic methanol extract (RYU) was shown to have the strongest antiproliferative efficacy against C6 cells. Results showed that RYU and ultrasonic methanol extract of R. ribes radix (RRU) were determined as the best carbonic anhydrase inhibitors. According to results of particle size, encapsulation efficiency, and release studies of chitosan NPs, it has been observed that they are suitable for application. At a concentration of 10 µg/mL, it was found that none of the R. ribes extracts exhibited cytotoxic action toward the NIH 3T3 cell line. According to results of particle size, encapsulation efficiency, and release studies of chitosan NPs, it has been observed that they are suitable for application. It was observed that none of the extracts of R. ribes at a concentration of 10 µg/mL showed cytotoxic activity in the NIH 3T3 cell line.

Green biosynthesis of selenium and zinc oxide nanoparticles using whole plant extract of Rheum ribes: Characterization, anticancer, and antimicrobial activity

Scientists are becoming interested in nanomedicine as a potential new approach to cancer detection and therapy in the twenty-first century. This paper presents the first investigation of the anticancer and antibacterial properties of selenium (Se) and zinc oxide (ZnO) nanoparticles obtained from Rheum ribes plant extract by a green synthesis method. Morphological and spectroscopic characterization of the synthesized nanoparticles was performed using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible (UV–Vis), which is a useful and straightforward technique for the preliminary characterisation of nanoparticles, dynamic light scattering (DLS) and X-ray diffraction (XRD) analysis. The size of the nanoparticles was determined to be 33 nm for Se-Nps and 32.8 nm for ZnO-Nps. The anticancer activity was assessed by the use of MTT, annexin V, caspase 3/7, and confocal microscopy imaging techniques. ZnO-Nps and Se-Nps were found to have significant antibacterial activity with MIC values for Escherichia coli (0.7 μg/mL, 0.63 μg/mL), and Staphylococcus aureus (1.56 μg/mL and 1.1 μg/mL). Furthermore, the antibacterial activity and the mechanism of action of the nanoparticles on E. coli and S. aureus bacteria were evaluated using microdilution and disc diffusion methods. In addition, the antiproliferative properties of ZnO-Np and Se-Np significantly suppressed the growth of A549 cells during a 24-hour incubation period (IC50 18.89 μg/mL ve 23.88 μg/mL). The results of the anti-cancer and anti-bacterial activity of the present study suggest that certain concentrations of Se-Np and ZnO-Np could be useful for pharmacological applications in cancer treatment and for coating surfaces for sterilization of medical equipment in healthcare settings, particularly in intensive care units.

Development and validation of a UHPLC-ESI-MS/MS method for the simultaneous determination of organic acids and phenolic compounds in Filipendula vulgaris, Polygonum divaricatum, Hypericum linarioides, and Rheum ribes

This research focused on investigating biologically active and pharmaceutically important phytochemicals using reliable and reproducible analytical techniques specifically designed for traditional medicinal plants. Considering the complex chemical diversity present in plant extracts, reliable identification methods are crucial. The goal of this study was to develop and validate a robust UHPLC-ESI-MS/MS method for the qualitative and quantitative analysis of organic acids (OAs) and phenolic compounds (PCs). With gradient elution of water containing 0.1 % formic acid and acetonitrile containing 0.1 % formic acid as the mobile phase, OAs and PCs were separated chromatographically on a C18 reversed-phase column. Through the use of an electrospray ionization source operating in negative ionization mode, these compounds were identified on a triple quadrupole tandem mass spectrometer. The validation results clearly indicate that the method exhibited linearity with a squared correlation coefficient (R2 ≥ 0.9986), demonstrating sensitivity (LOQ: 1.08 µg/L-10.79 µg/L), precision (RSD%≤2.73), and trueness (RE% ≤ 1.53) for the OAs and PCs found in the plants. The developed UHPLC-ESI-MS/MS method was successfully applied to the qualitative and quantitative analysis of OAs and PCs in Turkish plants, which are commonly used in traditional medicine. Our study identified a total of 12 OAs and PCs in F. vulgaris, 12 in P. divaricatum, 9 in H. linarioides, and 11 in R. ribes. In particular, gallic acid had the highest content in F. vulgaris (925.67 µg/g extract) and R. ribes (1358.78 µg/g extract), while H. linarioides (730.66 µg/g extract) and P. divaricatum (4003.02 µg/g extract) had relatively high levels of quinic acid. In conclusion, the developed UHPLC-ESI-MS/MS method allows the simultaneous analysis and quantification of 2 OAs and 33 PCs in plants and proves to be a valuable tool for evaluating the efficacy of traditional medicinal plants.

Green synthesis of carbon dot structures from Rheum Ribes and Schottky diode fabrication.

In this study, we aimed to synthesize new carbon dot structures (CDs) in a single step by using the plant Rheum Ribes for the first time and to contribute to the studies in the field of diode fabrication by using the new CDs. The CDs were obtained by hydrothermal synthesis, which is commonly used in the literature. TEM and zeta potential measurements were used to determine morphology and sizes of the CDs, and XRD, XPS, and FTIR and micro-Raman spectroscopy were used for structural characterization. Optical characterization of the CDs was done by absorption and steady-state fluorescence measurements. In the second part of the study, CDs were dripped onto silicon substrates, and a CDs thin film was formed by evaporation. A diode structure was obtained by evaporating gold with the shadow mask technique on the CDs film, and the current-voltage characteristics of this diode were examined. The synthesized CDs are spherical with an average size of 5.5 nm, have a negative surface charge and contain 73.3 atom % C, 24.0 atom % O, and 2.7 atom % N. The CDs exhibit fluorescence at approximately 394 nm. The layer thickness and bandgap energy of the prepared CDs film were calculated as 566 nm and 5.25 eV, respectively. The ideality factor and the measured barrier height (Φb) of the CDs-based Schottky diode were calculated as 9.1 and 0.364 eV, respectively. The CDs were used as semiconductor material in a Schottky diode, and the diode exhibited rectification behavior. The results obtained from this study showed that CDs can be applied in the field of electronics, apart from sensor studies, which are common application areas.

Chloroform-Methanol Extraction Antimicrobial Potential of Rheum Ribes Originating from Elazig/Aricak Province

Rheum ribes (R. ribes) has a variety of medicinal applications due to the presence of anthraquinone derivatives and other compounds. It was aimed to determine the potential antimicrobial effects on some gram-negative/positive pathogens, and lactic acid bacteria by agar well diffusion test following minimum inhibition concentrations (MIC) with liquid extract samples of R. ribes. Growth concentrations of R. ribes extract doses (14.17-0,89 mg/L) were applied to indicator microorganisms. MIC method used microbial density values compared to the control group. Result of the Agar well diffusion test, the best antibacterial effects were detected on L. monocytogenes and S. aureus and following B. subtilis (zone diameter of 18.72 and 18.32 mm, respectively). The R. Ribes extract showed a higher inhibitor effect than tetracycline antibiotic against L. monocytogenes. Similarly, S. aureus and E. faecalis., S. paratyphi A were more affected by R. Ribes extract than tetracycline antibiotic. The MIC test result, the highest inhibitory effects of R. ribes extract at a concentration of 0,89 mg/L for S. Paratyphi A strain, 3.54 mg/L for K. pneumonia, and 3.54 mg/L for E. coli RSSK 09036 were determined as 50.81%, 60.45%, and 60.40%, respectively. The highest inhibition effects of R. ribes at 14.17 mg/L (0.5 dilution concentration) concentration were determined at the rate of 80.12% for Bacillus clausii and 96.04% for B. subtilis. In the present study, it is thought that the differences between the antimicrobial effect and MIC tests seen in gram-positive, negative and probiotic bacteria may be related to the surface tension effect of the extract

Effects Of Some Fungal Secondary Metabolite Against Some Cancer Cell Line

The promising feature of the fungi from the marine environment as a source for anticancer agents belongs to the fungal ability to produce several compounds and enzymes which contribute effectively against the cancer cells growth. Moreover, the compounds produced during the secondary metabolic process acts by changing the cell morphology and DNA fragmentation leading to apoptosis of the cancer cells. When compared to the other chemicals in the investigation, gliotoxin demonstrated the most cytotoxic effect.

Investigation of adsorption, corrosion inhibition, synergistic inhibition effect and stability studies of Rheum ribes leaf extract on mild steel in 1 M HCl solution

BackgroundDue to high cost, toxicity of conventional inhibitors and environmental regulations, corrosion scientists have directed toward plant extracts as alternatives to conventional inhibitors. In this study, leaf extracts of Rheum ribes (RR leaf) were prepared, and their adsorption and protective effects on mild steel (MS) corrosion were investigated in 1.0 M HCl solution. The synergistic inhibition effect of iodide ions and the stability of surface inhibitor film were also studied. MethodsThe protection ability of extract was investigated using electrochemical techniques. The stability of surface film was evaluated by potentiodynamic and potentiostatic studies. After being exposed to the corrosive medium, the surface of metal was examined using SEM, EDX, AFM and contact angle measurements. Significant FindingsThe extract molecules formed an adherent and homogenous protective film on the MS surface. When the RR leaf extract concentration increased, a stronger inhibition effect against corrosive attack was obtained. At 1000 ppm extract concentration, the protection efficiency of RR leaf extract increased from 91.8% to 94.9% when 1000 ppm KI was added to the inhibited acid solution.

Adsorption and corrosion inhibition capability of Rheum ribes root extract (Işgın) for mild steel protection in acidic medium: A comprehensive electrochemical, surface characterization, synergistic inhibition effect, and stability study

The adsorption and inhibitory effect of Rheum ribes (RR) root extracts on mild steel (MS) corrosion in 1 M HCI solution were examined by electrochemical techniques. The characteristics of the electrode surface after exposure to corrosive solutions were investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The chemical composition and the distribution of the surface film was examined with energy dispersive X-ray spectroscopy (EDX). The hydrophilic or hydrophobic properties of the MS surface were investigated using contact angle (CA) measurements. According to the findings, molecules of RR root extract adsorb to the metal surface, which form a protective and uniform film. Increasing the concentration of RR root extract improves the resistance of the alloy's surface to corrosion attacks. The extract acts as a mixed-type corrosion inhibitor with dominantly cathodic action. The molecules of the extract predominate the anodic reaction in the presence of iodide ions. Physical interactions are the most important in the extract molecule adsorption. The synergy between the iodide ions and the molecules of the extract improves the extracts protection ability and the film's stability. The film of extract molecules on the surface of the steel reduces surface deterioration and increases hydrophobicity.
