Evaluation of African Neem Plant (Dogon Yaro) antibacterial activity against certain pathogenic organisms

The neem plant is a tropical evergreen plant native to the Indian sub-continent. It has been used in ayurvedic medicine for more than 4000 years due to its medicinal properties. The phytochemical screening carried out on the extract of Neem plant revealed the presence of some active ingredients such as alkaloids, tannins, saponins, and phenols also glycosides, steroids, Terpenoids, flavonoids, and phlobatanins are present in this extract. It was observed that alkanoids has a concentration of 0.52g/ml, tannins has a concentration of 9.00g/ml, saponins has a concentration of 1.99g/ml, flavonoid has a concentration of 0.62g/ml and phenol has a concentration of 0.024g/ml. The antimicrobial activity of the Leaf, Stem, Stem-bark and Root extract of Neem plant (Azadirachta indica) against some of the pathogenic bacteria such as E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Staphylococcus epidermidis, was determined. This was done by using alcoholic and water extracts of Neem leaves, stem, stem bark and roots. Varying concentration of each extracts 200mg/ml, 150mg/ml and 100mg/ml were prepared and tested. When compared with Gentamycin 10mg, the Ethanol Extract of Neem Root shows maximum inhibition on Pseudomonas aeruginosa, Staphylococcus epidermidis, Staphylococcus aureus and E. coli in an ascending order, followed by the ethanol extract of Neem Leaf which shows maximum inhibition on Pseudomonas aeruginosa, Staphylococcus aureus, E. coli and Staphylococcus epidermidis in an ascending order. Conclusively, this can explain the rationale for the use of the plant in treating infections in traditional medicine. The plant could be a veritable and cheaper substitute for conventional antibiotics since it is easily obtainable and the extract can easily be made via a simple process of maceration or infusion. However, further research is necessary to determine and purify the active components against micro-organisms.

Toxicity and Repellency of (E/Z)-3-Butylidenephthalide: A Natural Compound Isolated from Ligusticum porteri Root Extract Evaluated Against Imported Fire Ants (Hymenoptera: Formicidae)

Imported fire ants are pests of significant importance, especially in the southern United States. We tested (E/Z)-3-butylidenephthalide, a natural compound that was isolated from the ethanolic extract of Ligusticum porteri roots, as a repellent and toxicant against workers of imported fire ants. A series of serial concentrations, starting from 156 µg/g until failure, were tested using digging bioassays. Workers removed significantly less sand from the vials treated with (E/Z)-3-butylidenephthalide as compared to the ethanol control. Based on sand removal data, (E/Z)-3-butylidenephthalide treatment resulted in a more significant digging suppression against red imported fire ant workers at concentrations ranging between 19.5 and 0.6 µg/g than the solvent control whereas sand removal at 0.3 µg/g was similar with the solvent control. Black imported fire ants showed repellency at serial concentrations ranging between 19.5 and 0.15 µg/g whereas the hybrid imported fire ants showed repellency between 19.5 and 4.9 µg/g. In DEET treatments, red and black imported fire ants showed repellency at dosages of 125 to 62.5 µg/g, whereas the treatment failed at the dose of 15.6 µg/g in hybrid fire ants. (E/Z)-3-butylidenephthalide with LC50 values of 11 and 16.4 µg/g was toxic against red and black imported fire ants, respectively, followed by hybrid imported fire ants (LC50 = 104.7 µg/g). Fipronil with LC50 values of 0.49, 0.33, and 0.53 µg/g against red, black, and hybrid fire ants, respectively, was more toxic than (E/Z)-3-butylidenephthalide. In residual bioassay, toxic activity lasted for 3 weeks at dosages of 250 and 500 μg/g against HIFA. In residual bioassay, toxic activity lasted for 3 weeks at dosages of 250 and 500 μg/g against HIFA. The high repellency and toxicity of (E/Z)-3-butylidenephthalide against imported fire ants makes it a natural compound of interest for further evaluation under natural field conditions.

Assessing the efficacy of Stemona collinsiae roots extract against third-stage larvae of Gnathostoma spinigerum and its safety profiles

Gnathostomiasis, caused by the advanced third-stage larvae of Gnathostoma spinigerum, demands novel treatment avenues. The ethanolic root extract of Stemona collinsiae has been postulated to have anthelminthic properties, suggesting its potential as an alternative remedy. In this study, S. collinsiae roots were collected, identified, and extracted with 95 % ethanol. The crude extracts were standardized using didehydrostemofoline as chemical marker. The efficacy of the S. collinsiae root extract against third-stage larvae of G. spinigerum and its toxicity to Wistar rats were evaluated. Both in vitro and in vivo tests were performed, where the in vitro tests assessed the anthelminthic potential of S. collinsiae extract against G. spinigerum larvae, while in vivo tests examined the extract's efficacy against G. spinigerum larvae in infected Wistar rats and the efficacy was compared with albendazole. Parallelly, Wistar rats underwent acute and sub-chronic toxicity tests to establish the safe dosage of the extract. The in vitro tests showcased significant anthelminthic activity, marked by discernible morphological alterations in the exposed larvae. Acute toxicity proved fatal at 2000 mg/kg body weight, while a dose of 300 mg/kg proved non-toxic. Using the Globally Harmonized Classification System, an LD50 of 500 mg/kg was determined. In vivo trials revealed a pronounced decline in G. spinigerum larvae among rats treated with the S. collinsiae extract. The larvae were also observed to be encysted post-treatment, while those treated with albendazole were not encysted. The S. collinsiae extract, with its noteworthy in vitro efficacy and favorable safety metrics in rodents, can be a potential anthelminthic agent. The diminished inflammatory response compared to albendazole hints at S. collinsiae being a safer gnathostomiasis treatment alternative. The promising results in these preliminary trials warrant a deeper investigation to determine the root extract's optimal dosing, suitable delivery methods, and its broader clinical implications.

Exploring the Therapeutic Potential of Sphenocentrum jollyanum Root Extract in Malaria Treatment: Efficacy, Safety, and Future Directions

Malaria remains a critical global health challenge, necessitating the exploration of novel therapeutic agents. This review examines the therapeutic potential of the ethanol root-extract of Sphenocentrum jollyanum, a plant traditionally used in West Africa for malaria treatment. Utilizing the Plasmodium berghei rodent model, which mirrors human malaria, we assess the extract’s efficacy in restoring haematological markers, safety profile, and potential as an adjunct or alternative therapy. Sphenocentrum jollyanum, known for its rich phytochemical composition, including alkaloids, flavonoids, saponins, tannins, and terpenoids, has demonstrated significant restorative effects in preliminary studies. The extract improved hemoglobin levels, red blood cell counts, and platelet counts in infected mice, indicating potential benefits in mitigating malaria-induced anemia and other haematological abnormalities. Its mechanisms of action include antioxidant, anti-inflammatory, and immunomodulatory effects. Despite its promising results, rigorous safety evaluations are necessary, including acute and chronic toxicity studies, to ensure its safe use. Future research should focus on clinical trials to validate efficacy, optimize dosage, and explore combination therapies with standard antimalarial drugs. The review emphasizes the need for standardized preparation methods, quality control, and integration into public health strategies to enhance malaria management, particularly in resource-limited regions. Keywords: Sphenocentrum jollyanum Root Extract, Malaria, Treatment, Efficacy, Safety.

Assessment and comparison of phytochemical constituents and biological activities of endemic Odonterrhena floribunda (Brassicaceae) from Türkiye

ABSTRACT This study aimed to evaluate the phenolic profile, antioxidant, antibacterial, and antidiabetic properties of ethanolic and methanolic extracts of the different parts of the endemic Odontarrhena floribunda. The antioxidant activities of O. floribunda were determined with 1,1-diphenyl-1-picrylhydrazyl (DPPH) and the copper-reducing antioxidant capacity (CUPRAC) assays. The strongest antioxidant activity was recorded in methanolic root extract (IC50:1.68±0.25 μg/mL) for DPPH and ethanolic root (λ450:0.68±0.20) extract for CUPRAC. Antibacterial activities of the extracts were displayed by the Resazurin Microplate Method (REMA). All plant extracts analyzed demonstrated stronger effects on Acinetobacter baumannii (ATCC 02026) than those of the standard compound. The in vitro α-amylase and α-glucosidase inhibitory of the plant extract were assessed using the Iodine method. Except for the methanol leaf extract, all other extracts showed strong α-glucosidase inhibitory activity (0.88–2.13 mmolTE/g). These results show that this endemic O. floribunda is a potential natural antioxidant, antibacterial, and enzyme inhibitor source.

Therapeutic Potential of Salvia miltiorrhiza Root Extract in Alleviating Cold-Induced Immunosuppression.

The interaction between environmental stressors, such as cold exposure, and immune function significantly impacts human health. Research on effective therapeutic strategies to combat cold-induced immunosuppression is limited, despite its importance. In this study, we aim to investigate whether traditional herbal medicine can counteract cold-induced immunosuppression. We previously demonstrated that cold exposure elevated immunoglobulin G (IgG) levels in mice, similar to the effects of intravenous immunoglobulin (IVIg) treatments. This cold-induced rise in circulating IgG was mediated by the renin-angiotensin-aldosterone system and linked to vascular constriction. In our mouse model, the cold-exposed groups (4 °C) showed significantly elevated plasma IgG levels and reduced bacterial clearance compared with the control groups maintained at room temperature (25 °C), both indicative of immunosuppression. Using this model, with 234 mice divided into groups of 6, we investigated the potential of tanshinone IIA, an active compound in Salvia miltiorrhiza ethanolic root extract (SMERE), in alleviating cold-induced immunosuppression. Tanshinone IIA and SMERE treatments effectively normalized elevated plasma IgG levels and significantly improved bacterial clearance impaired by cold exposure compared with control groups injected with a vehicle control, dimethyl sulfoxide. Notably, bacterial clearance, which was impaired by cold exposure, showed an approximately 50% improvement following treatment, restoring immune function to levels comparable to those observed under normal temperature conditions (25 °C, p < 0.05). These findings highlight the therapeutic potential of traditional herbal medicine in counteracting cold-induced immune dysregulation, offering valuable insights for future strategies aimed at modulating immune function in cold environments. Further research could focus on isolating tanshinone IIA and compounds present in SMERE to evaluate their specific roles in mitigating cold-induced immunosuppression.

Tapping the potential of Calotropis procera hairy roots for cardiac glycosides production and their identification using UHPLC/QTOF-MS.

The present work deals with the establishment of hairy root cultures from different explants of C. procera using Agrobacterium rhizogenes strain A4. A high transformation frequency (95%) was obtained from leaves followed by cotyledons (81.6%) and hypocotyls (38.3%). Genetic transformation of hairy roots was confirmed through PCR by amplifying a 400 bp fragment of the rolB gene. Hairy roots were highly branched, possessed plagiotropic and rapid growth on hormone-free ½ B5 medium. Ten cardiac glycosides, including calotropagenin, calotoxin, frugoside, coroglaucigenin, calotropin, calactin, uzarigenin, asclepin, uscharidin, and uscharin, based on their specific masses and fragmentation properties were identified in ethanolic extracts of hairy roots by ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry UHPLC/QTOF-MS. This protocol could be used as a powerful tool for large-scale in vitro production of highly valued cardiac glycosides and for further transcriptomics or metabolomics studies.

Study of Antidiabetic Properties of Berberis asiatica and Withania somnifera in Streptozotocin-Nicotinamide-Induced Type II Diabetes Mellitus in Wistar Rats.

Background and aim Diabetes is a chronic metabolic disorder characterized by elevated blood glucose levels. Although current antidiabetic drugs are highly effective, they are associated with various adverse drug reactions, including life-threatening hypoglycemia, skin rashes, and gastrointestinal intolerance, in addition to being costly. This animal-based experimental study aims to develop a herbal alternative or adjuvant to current antidiabetic drugs usingBerberis asiatica(BA)andWithania somnifera(WS), which could potentially have fewer adverse drug reactions and reduce the required dose of existing antidiabetic medications. Material and methods Seventy-eight adult albino Wistar rats weighing between 150 and 250 gwere used for the study. Diabetes mellitus (DM) was induced by intraperitoneal (i.p) injections of streptozotocin (STZ) (65 mg/kg) 15 minutes after nicotinamide (NIC) (110 mg/kg) administration. As the diabetes was confirmed (blood glucose level > 250 mg/dL), rats were divided into 13 different groups mentioned. The standard antidiabetic drugs (metformin [MET] and glimepiride [GLI]) and polyherbal combinations (PHC) (BA + WS) were administered orally, individually (WS and BA), and in combination (BA + WS). Blood samples were collected for biochemical analysis using the tail vein prick method. The study is based on a total of 13 groups, six rats in each group.Groups 1 and 2 (normal control [NC] and diabetic control [DC]) received distilled water at a dose of 10 mL/kg orally for 28 days. Groups 3-5(BA250, 500, and1000) received dried ethanolic root extract of BA at a dose of 250, 500, and 1000 mg/kg orally, respectively, for 28 days. Groups 6-8(WS250,500, and 1000) received dried ethanolic root extract of WS at a dose of 250, 500, and 1000 mg/kg orally, respectively, for 28 days. Groups 9-11 (PHC250, 500, and 1000) received dried ethanolic root extract ofBA + WSat a dose of 250, 500, and 1000 mg/kg orally, respectively, for 28 days. Groups 12 and 13 (MET and GLI) received standard drugs MET and GLI at a dose of 250 and 10 mg/kg orally, respectively, for 28 days. Results The dried ethanolic root extract of medicinal herbal plantsBAandWSand their combination exhibited significant antidiabetic efficacy. PHChas been shown to have a superior antidiabetic effect than individuals. PHC 500 and 1000 showed blood glucose levels similar to those of the GLI group (P < 0.05). Additionally, PHC 1000 showed blood glucose levels similar to those of the MET group (P < 0.05). Conclusion Our results indicate that bothBAandWSpossess hypoglycemic activity, and their combination also has a synergistic antidiabetic effect compared to the individual extract. These findings are promising in developing new safe and cost-effective herbal combinations as alternatives or additives to currently used synthetic antidiabetic drugs.

LC-MS/MS analysis of didehydrostemofoline from Stemona collinsiae roots extracts in rats plasma and pharmacokinetics profile after oral administration

Stemona collinsiae Craib., Stemonaceae, has been traditionally used as medicinal plants for insecticides, treatment of parasitic worms and various diseases in Southeast Asian countries. Its ethanolic root extract has been postulated for anthelminthic activities which has a potential for development for human gnathostomiasis drug. To investigate the pharmacokinetic profile, liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) method for the quantification of didehydrostemofoline in rats' plasma was developed and validated. The chromatographic separation was performed on a C18 column using 1 mM ammonium acetate in water and methanol (50:50, v/v). Tetrahydropalmatine was used as an internal standard. The multiple reaction monitoring mode was used for quantitative analysis. The validated method showed good sensitivity, linearity, precision, and accuracy. The results of stability showed that didehydrostemofoline was stable in the extracted samples in auto-sampler for 24 h and in the plasma samples under room temperature for 24 h, −20 °C for 1 month, and after three freeze-thaw processes. The developed method was applied to the pharmacokinetic study of didehydrostemofoline after oral administration of S. collinsiae root extract. Didehydrostemofoline was rapidly absorbed from the gastrointestinal tract. The time to peak drug concentration was 1.75 ± 0.62 h with maximum drug concentration of 1152.58 ± 271.18 ng/mL. Didehydrostemofoline was rapidly eliminated from the body with terminal half-life of 1.86 ± 0.50 h. Calculated drug clearance of didehydrostemofoline was 96.82 ± 23.51 L/h and volume of distribution was 260.40 ± 96.81 L. The present study provided useful data for understanding drug disposition in the body with dynamic time-course which could be beneficial for further clinical trials.

Effects of Rauwolfa vomitoria (Akata) and Olax subscorpioidea (Asaja) Roots on Hematology of Chicken Type II Collagen-Freund’s Adjuvant-induced Rheumatoid Arthritis in Albino Rats

This study evaluated the effects of ethanol and aqueous root extracts of Rauwolfia vomitoria and Olax subscorpioidea on Chicken type II collagen in Complete Freund’s Adjuvant-induced arthritis in albino rats. A total of 225 albino rats, weighing between 120-200 g, were used and divided into 15 groups of 15 rats each. Rheumatoid Arthritis (RA) was induced by administering 0.1 ml of Chicken type II-Complete Freund’s Adjuvant into the left hind paw. The study duration was 32 days, during which the arthritic rats were treated with Rauwolfia vomitoria and Olax subscorpioidea root extracts at doses of 400 mg, 600 mg, and 800 mg/kg body weight. The sub-lethal toxicity study revealed significant increases (P&lt;0.05) in WBC, platelet, and differential counts, along with significant reductions (P&lt;0.05) in RBC count, PCV, and HB in the adjuvant induced arthritic rats compared to the negative control group. However, treatment with the plant extracts (groups 4-15) significantly reversed these trends towards normal levels compared to the untreated arthritis group (group 2) within the 32-day period. The ameliorative effects of the extracts were both time- and dose dependent (P&lt;0.05). This study concludes that the ethanol and aqueous root extracts of Rauwolfia vomitoria and Olax subscorpioidea effectively ameliorate arthritis symptoms in albino rats, potentially due to the presence of active chemical constituents. These findings provide scientific evidence supporting the therapeutic use of these plant extracts in managing arthritis.

Discovery of new antibiotics using AI-guided spectroscopy and 3D drug-protein computer simulation technologies to combat MDR bacteria-associated mortality

Multidrug-resistant (MDR), extensively drug-resistant (XDR), and totally drug-resistant bacteria can cause sepsis and death in patients due to their ability to inactivate most antibiotics, including ampicillin, tetracycline, streptomycin, chloramphenicol, erythromycin, and ciprofloxacin. This paper aims to review recent advancements in synthetic antibiotics, lantibiotics, and phytoantibiotics and to present our research on phytoantibiotics, specifically focusing on CU1 and NU2. While third- and fifth-generation synthetic antibiotics such as meropenem, moxifloxacin, amikacin, and tigecycline are currently relied upon for treating MDR infections, research is underway to develop peptide antibiotics known as lantibiotics (e.g., nisins, bacteriocins, and salivaricins). Lantibiotics such as nisin-A and salivaricin-B have demonstrated efficacy in curing numerous MDR infections, while phytochemicals such as artemisinin and quinine have shown effectiveness against chloroquine-resistant Plasmodium falciparum infections (malaria). In our study, we utilized techniques such as mass spectroscopy, nuclear magnetic resonance, and Fourier transform infrared spectroscopy in conjunction with artificial intelligence (AI) and computer simulation technologies to determine the structure of phytochemicals. Our results revealed that CU1, derived from Cassia fistula bark ethanol extract, exhibits potent antibiotic activity against XDR bacteria by targeting the RNA polymerases of Escherichia coli and Mycobacterium tuberculosis. Consequently, our MDR-Cure extract containing CU1 represents a promising antibacterial Ayurvedic medicine specifically tailored for skin and nail infections. Similarly, NU2 poly-fluorophosphate-glycosides from Suregada multiflora roots ethanol extract exhibited strong inhibitory effects on XDR bacteria by targeting DNA topoisomerase I. Recently, many cyclic peptide antibiotics have been synthesized in vitro using computer-guided AI technologies to predict 3D drug-enzyme interactions and are currently undergoing clinical trials. Our ultimate goal is to combat XDR bacteria-associated deaths, which are predicted to escalate as we approach 2050.

The Flavonoids, Phenolics, and Antioxidant Activity from Ethanol Extract of Fibraurea tinctoria Lour

Oxidative stress has long been associated with increased risk for several diseases. Antioxidant is a molecule that inhibits the oxidation of other molecules and delays or prevents oxidative damage. Natural phenolic and flavonoid compounds are plant secondary metabolites directly contributing to antioxidant activity. Fibraurea tinctoria Lour, often called the yellow root, is a plant that has long been known in the traditional medicine of the native tribes of West Kalimantan to treat several diseases, including malaria, jaundice, and diabetes. This study aimed to quantify the total phenolic (TPC) and flavonoid (TFC) contents and antioxidant activity of the ethanol extract of yellow root stems. Yellow root stems were extracted by maceration in 96% ethanol for four days. The total phenolic, flavonoid, and antioxidant activities were measured using the Folin-Ciocalteu, AlCl3, and DPPH methods. Phytochemical screening showed that the ethanol extract of yellow root stems contains phenolics, flavonoids, alkaloids, saponins, tannins, and steroids/triterpenoids. The total phenol and flavonoid contents were 40.2 mg GAE/g extract and 61.2 mg QE/g extract, respectively. The ethanol extract of yellow root stems showed moderate DPPH scavenging activity, with an IC50 of 152.13 ppm. From this study, it can be concluded that this plant could be a potential source of natural antioxidants.

T-Test revealed that there is a significant difference on zone of inhibitions of the S. aureus and E. coli tested under Tubli (D. elliptica Benth) ethanolic root extract. The presence of phytochemicals suggests that D. elliptica has a potential antimicrobial property that could serve as a natural source of traditional medicine for treatment of various diseases.

Invitro antibacterial activity of bark, leaf and root extracts of combretum molle plant against streptococcus equi isolated from clinical cases of strangles in donkeys and horses

BackgroundEffective therapy for many infections is becoming difficult due to the evolutionary development of drug resistance, and hence, the development of alternative treatment options mainly from herbs is crucial. The objective of this study was to investigate the antibacterial effects of ethanol extracts of stem bark, leaves and roots of Combretum molle against Streptococcus equi isolated from clinical cases of strangles using in vitro tests.MethodsPlant extraction was performed using a maceration technique with 80% ethanol. The mean zone of inhibition was determined using the agar well diffusion method. Six serial dilutions with different concentrations (10%, 5%, 2.5%, 1.25%, 0.625% and 0.3125%) of each plant extract were prepared using dimethyl sulfoxide (DMSO). A modified agar microdilution method was used to determine the minimum inhibitory concentration (MICs) of the extracts.ResultsThe results revealed that all plant extracts showed significant antibacterial activity. The root extract showed the best antibacterial effect compared to the others at all concentrations, with MZI values of 27.5, 23.225, 20.5, 17.9, 15.65 and 12.25 for the respective concentrations mentioned above and an MIC of 250 µg/ml. It was followed by the stem bark extract, which had MZI values of 24.67, 22.35, 18.225, 16.175, 11.125 and 8.2 millimeters and an MIC of 375 µg/ml. The leaf extract also had significant activity, with MZI values of 20.175, 18.25, 15.7, 13.125, 9.4 and 6.75 in millimeters and an MIC of 500 µg/ml. There was a direct relationship between the concentrations of the plant extracts and the level of inhibition.ConclusionThe test plant extracts were compared with the conventional antibiotic penicillin G, and the results indicated that the parts of the test plant have significant antibacterial activity, which may support traditional claims and could be candidates for alternative drug discoveries.
