Computational Screening and Biochemical Analysis of Ricinus Communis Linn Root

The goal of the current investigation was to computational screening and biochemical evaluation of Riconus communis Linn's root. The phytochemicals from the root of Ricinus communis were extracted using methanol and water. Via phytochemical screening with LC-MS, it was possible to identify the greater number of phytoconstituents in the ricinus communis linn root extracts. Potential sources of novel drugs and therapeutic leads included the plant's active phytoconstituents. The study's findings indicated that the methanolic extract of Ricinus communis root includes compounds with anticancer properties and some pharmacological active moieties. Esters, bioflavonoids and phenolic compounds have been estimated by chemical analysis and these were further identified with the help of LC-MS analysis. Thus, the raw root extracts of Ricinus communis may serve as fresh sources for the creation of novel plant-based medicines for the treatment of various illnesses. Since the plant already contains phenolic compounds, esters, and flavonoids, and the potential toxicity of a few specific components were investigated. It can be employed for the approaching research because it has been found that it is less dangerous and active.

Preliminary phytochemical screening and antibacterial effects of root bark of Ferula communis (Apiaceae).

Plants are widely used in traditional medicine because they contain a high concentration of antimicrobial agents, serving as the foundation for medicines. The aim of this study was preliminary identification of phytochemicals and assesses the antimicrobial activity of extracts of Ferula communis root bark. Plant was collected, and standard qualitative procedures were conducted. The plant samples were extracted with 99.9% methanol and 80% ethanol. To identify phytochemicals found in plants, a preliminary phytochemical analysis was performed. Agar diffusion tests, minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) were performed to evaluate antibacterial activity. The preliminary phytochemical analysis of the ethanol and methanol extract revealed positive results for flavonoids, coumarins and tannins. Terpenoids and anthraquinones were detected only in the methanol extract. The extract of Ferula communis showed an antibacterial effect on both gram-negative and gram-positive bacteria in a concentration-dependent manner. The average zone of inhibition for gram-positive bacteria was 11mm, whereas for gram-negative bacteria, it was 9mm. The MIC and MBC values also varied with the type of bacteria. In all bacterial species tested, the mean MBC value was similar to the MIC. Different phytochemicals were detected in extracts of the root bark of F. communis and extracts showed antibacterial effects in a concentration-dependent manner. Therefore, further purification and evaluation of the extracts and antioxidant activity of the plant should be investigated.

Neurological and Molecular Interactions of Phytoconstituents from Ricinus communis Root Extract- A Pharmacological and Computational Approach

The majority of epileptic patients takes numerous anticonvulsant medications and is still not treated successfully. These medications' produce chronic side effects and drug interactions, which restrict their use, constitute their major drawback. On the other hand, the fact that nature has given us plants that can be used as safe, all-natural treatments for illnesses with little side effects and minimal drug interactions has prompted researchers to focus on herbal remedies with anticonvulsant potential. The antiepileptic potential of the methanolic root extract of Ricinus communis was investigated in rodent models. Molecular docking studies using Schrodinger software was employed to study interactions with active site using PDB ID: 4MS4 (GABA agonist’s), 3WFG (glutamate antagonist), 5HCV (aspartate antagonist), 6J8G (sodium channel antagonist). At 30 and 60 minutes, MERC effectively diminished various convulsive phases and provided strong defence against the MES model. In PTZ, MERC extract treated groups at a dose (200 mg/kg and 400 mg/kg) showed significant antiepileptic activity with percentage protection of 24% and 33% respectively against seizures and significantly (* = p<0.0001) increased the latency of the seizures. Molecular docking studies confirmed the GABA agonist’s effects, and the results revealed that quercetin. gallic acid, luteolic acid, gentixic acid, catechin, vanillic acid, ricinoilc acid and standard phenytoin, clonazepam has highest Glide scores against all the selected proteins which indicates a stronger receptor -ligand binding affinity. From in vivo and molecular docking results it is clear that methanolic root extract of Ricinus communis possessed significant antiepileptic activity.

Antifungal Activity and Mechanism of Action of Different Parts of Myrtus communis Growing in Saudi Arabia against Candida Spp.

Discovering new antifungal drugs from natural products is a key target for the treatment of infections, such as candidiasis and other Candida-related infections. As current therapeutic drugs for the treatment of infections, such as candidiasis and other Candida-related infections, have adverse effects on human health, discovering new antifungal drugs from natural products is urgently needed. The objective of this study was to evaluate the antifungal activity of the methanolic and sodium phosphate buffer extracts derived from various parts of Myrtus communis, a plant that is traditionally used in Saudi Arabia, against Candida albicans (ATCC 10213), Candida glabrata (ATCC 2001), Candida kefyr (ATCC 66028), Candida parapsilosis (ATCC 22019), and Candida tropicalis (ATCC 750). A well diffusion assay was performed to assess the antifungal activity through the measurement of the zone of inhibition. Of the extracts, those extracted with methanol from the roots and leaves displayed strong inhibitory activity against Candida glabrata ( 23.5 ± 0.12 and 20.7 ± 0.22 , respectively), at 50 mg/ml, with 5 mg/ml fluconazole administered as the standard control. The minimal inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values were 12.5 mg/ml and 25 mg/ml for the M. communis root extract and 25 mg/ml and 50 mg/ml for the M. communis leaf extract against Candida glabrata. The results were confirmed by scanning electron microscopy (SEM) imaging of the control and treated strains of Candida glabrata. Based on SEM, these extracts could alter the morphology and cause loss of cell integrity. The effect of M. communis root and leaf extracts on Candida cells was also determined by measuring the absorbance at 260 nm after treatment for 1 h at 37°C. Interestingly, the 260 nm absorbing material was higher in Candida glabrata than in the resistant strain, Candida parapsilosis (ATCC 22019). Based on our findings, the crude methanolic extract of M. communis roots and leaves exhibited good antifungal activity against the Candida glabrata strain. SEM results and estimation of the 260 nm absorbance material proved that the extract might act on the cell wall and cell membrane of Candida cells, further leading to cell death.

Effect of Ferula communis L. on reproductive parameters in Awassi ewes

Nutrient composition of the diet affects follicular activity, embryonic development and reproductive hormones in ruminants. The objective of the present study was to investigate the effects of Ferula communis L. on some reproductive parameters of Awassi sheep. The experiment was carried out on 29 (15-16 months old) Awassi ewes. All ewes were allocated to receive either a control (14% CP and 11.7 MJ ME/kg, n=9) or a diet supplemented with 5% (75g, n=10) or 10% (150g, n=10) powdered F. communis root, respectively for 21 days. Oestrus was synchronized using intravaginal sponges, while oestrus behaviour was observed 24, 36 and 48h after the sponge removal. Blood samples were collected for the assessment of oestradiol and LH. At the end of the 21-day period, animals were slaughtered and ovarian structures were recorded. Corpora lutea tissues were cultured in vitro, and progesterone production was measured. The results indicate that the treatment of animals with 5% of F. communis root increased the percentage of animals in heat (80%, 60% and 10% for 5C, 10C, and the control group, respectively). Furthermore, the number of small follicles (1-3 mm) in treated groups was significantly higher than those of the control group. Moreover, the number of large follicles (>4 mm) in the control group was higher than those of the treatment groups. Plasma concentration of oestrogen and LH peak were similar in the control and treatment groups. Progesterone production by luteal cells cultured in vitro was higher for both treatment groups compared to the control. Herewith, supplementation of the diet of Awassi Sheep with F. communis root during the breeding season may enhance ovulation rate and luteal activity.

Antioxidative response in leaves and allelochemical changes in root exudates of Ricinus communis under Cu, Zn, and Cd stress

We have previously reported that Ricinus communis is a good candidate for the phytoremediation of Cd- and Zn-contaminated soil and for fuel production. In this study, changes in the activity of antioxidant enzymes (superoxide dismutase, SOD; catalase, CAT; and guaiacol peroxidase, POD) and the contents of chlorophyll and malondialdehyde (MDA) in R. communis leaves under Cu, Zn, and Cd stress were examined. Compounds from the exudate of R. communis roots were collected and analyzed using GC-MS chromatograms. The results of enzyme activity showed that Cd treatment significantly increased the SOD content of R. communis leaves and slightly elevated the CAT content, whereas the POD content increased markedly at low Cd treatment concentrations and decreased as Cd concentrations increased. Zn treatment distinctly elevated SOD and POD content in R. communis leaves but had no great influence on CAT content. Cu treatment slightly increased CAT activity, while Cu did not evidently change SOD and POD activity. We found 17, 29, 18, 18, and 33 different compounds in the R. communis root exudates from the control group and Cd, Cu, Zn, and Cd+Cu+Zn treatment groups, respectively. The root exudates mainly included ester, alcohol, ether, amide, acid, phenol, alkanes, ketone, aromatic hydrocarbon, and nitrile compounds. However, the root exudates of R. communis grown in uncontaminated soils were dominated by esters, alcohols, and ethers. Single Cu or Zn treatment slightly changed the root exudates, which were dominated by esters, alcohols, and amides. In the Cd and Cd+Cu+Zn treatment groups, the compositions of root exudates apparently increased, with alkanes as the major species (> 88%).

New anti-inflammatory triterpene from the root of Ricinus communis

Liquid–liquid partitioning of Ricinus communis root methanol extract resulted in enrichment of compounds. Purification of the n-hexane fraction led to the isolation and characterisation of two triterpenes: one known compound lupeol (1) and a new diketone pentacyclic triterpene named as erandone (urs-6-ene-3,16-dione) (2), from the plant. Their structures were determined by various spectroscopic techniques. Crude methanolic, enriched n-hexane fraction and isolates at doses 100 mg/kg p.o. exhibited significant (P < 0.001) anti-inflammatory activity in carrageenan-induced hind paw oedema model.

Bio-monitoring for uranium using stream-side terrestrial plants and macrophytes

This study evaluated the abilities of various plant species to act as bio-monitors for environmental uranium (U) contamination. Vegetation and soil samples were collected from a U processing facility. The water-way fed from facility storm and processing effluents was the focal sample site as it represented a primary U transport mechanism. Soils and sediments from areas exposed to contamination possessed U concentrations that averaged 630 mg U kg(-1). Aquatic mosses proved to be exceptional accumulators of U with dry weight (dw) concentrations measuring as high as 12,500 mg U kg(-1) (approximately 1% of the dw mass was attributable to U). The macrophytes (Phragmites communis, Scripus fontinalis and Sagittaria latifolia) were also effective accumulators of U. In general, plant roots possessed higher concentrations of U than associated upper portions of plants. For terrestrial plants, the roots of Impatiens capensis had the highest observed levels of U accumulation (1030 mg kg(-1)), followed by the roots of Cyperus esculentus and Solidago speciosa. The concentration ratio (CR) characterized dry weight (dw) vegetative U levels relative to that in associated dw soil. The plant species that accumulated U at levels in excess of that found in the soil were: P. communis root (CR, 17.4), I. capensis root (CR, 3.1) and S. fontinalis whole plant (CR, 1.4). Seven of the highest ten CR values were found in the roots. Correlations with concentrations of other metals with U were performed, which revealed that U concentrations in the plant were strongly correlated with nickel (Ni) concentrations (correlation: 0.992; r-squared: 0.984). Uranium in plant tissue was also strongly correlated with strontium (Sr) (correlation: 0.948; r-squared: 0.899). Strontium is chemically and physically similar to calcium (Ca) and magnesium (Mg), which were also positively-correlated with U. The correlation with U and these plant nutrient minerals, including iron (Fe), suggests that active uptake mechanisms may influence plant U accumulation.

Antiasthmatic activity of Ricinus communis L. roots

Objective To evaluate the antiasthmatic activity of Ricinus communis ( R. communis) Linn (Euphorbiaceae) to validate its traditional use. Methods The antiasthmatic activity of ethanol extract of R. communis (ERCR) root was evaluated on milk induced leucocytosis and eosinophilia in mice, mast cell degranulations in mice and passive cutaneous anaphylaxis in rats at (100-150 mg/kg). Results The ERCR significantly decreases milk induced leucocytosis and eosinophilia and protect degranulations of mast cells in mice. At the same dose ERCR inhibited passive cutaneous anaphylaxis in rats. Phytochemical study revealed the presence of steroids, saponin, alkaloids, flavonoids, and glycosides. Conclusions The flavonoids and saponins are reported to possess mast cell stabilizing and antianaphylactic activity. Hence ERCR shows antiasthmatic activity may be due to presence of flavonoids and/or saponins.

Anti-inflammatory and free radical scavenging activity of Ricinus communis root extract

Anti-inflammatory and free radical scavenging activities of the methanolic extract of Ricinus communis (RCM) (Euphorbiaceae) Linn. root was studied in Wistar albino rats. The methanolic extract at doses 250 and 500 mg/kg p.o. exhibited significant ( P < 0.001) anti-inflammatory activity in carrageenan-induced hind paw edema model. The extract at the dose of 500 mg/kg p.o. also exhibited significant ( P < 0.001) anti-inflammatory activity in cotton pellet granuloma model. The methanolic extract showed significant free radical scavenging activity by inhibiting lipid peroxidation initiated by carbon tetrachloride and ferrous sulphate in rat liver and kidney homogenates. The extract enhanced free radical scavenging activity of stable radical 2,2-diphenyl-1-picryl-hydrazyl (DPPH ), nitric oxide and hydroxyl radical in in vitro assay methods. The results of the study indicate that the methanolic extract of Ricinus communis root possess significant anti-inflammatory activity in acute and chronic inflammatory models in rats. The observed pharmacological activity may be due to the presence of phytochemicals like flavonoids, alkaloids and tannins present in the plant extract with various biological activites.

Sulfhydryl localization and tetrazolium reduction. I. Reversible inhibition of its reduction by N-ethyl maleimide.

The sulfhydryl inhibitor N-ethyl maleimide completely inhibited the reduction of 2,3,5-triphenyltetrazolium chloride in meristematic and embryonic vascular tissues of Coleus sp. stems, Ricinus communis root tips, ungerminated Tea mays embryos, and epicotyls and coleoptiles of germinated Tea mays embryos, in a concentration of 200 mg/lit. Inhibition was reversed by the addition of cysteine or reduced glutathione (200 mg/lit) to the inhibitor medium. N-ethyl maleimide was effective also in blocking the nitro-prusside and 1-(4-chIoromercuriphenylazo)-naphthol-2 sulfhydryl staining reactions, but other substituted maleimides were ineffective in inhibiting the tetrazolium reaction in these tissues. Experiments were conducted to determine the histological pattern of sulfhydryl groups as indicated by a modification of the Bennett 1-(4-chloro-mercuriphenylazo)-naphthol-2 test and a modification of the Rap-kine nitroprusside test in certain plant tissues. A positive correlation was observed between tissues reducing the tetrazolium indicator and tissues exhibiting sulfhydryl localization as indicated by the nitroprusside reagent (trichloroacetic acid pretreated) and 1—(4— chloromercuriphenylazo)—naphthol—2.
