Odontites linkii subsp. cyprius Ethanolic Extract Indicated In Vitro Anti-Acanthamoeba Effect

This study aims to investigate three endemic ethanolic leaf extracts from Cyprus for anti-Acanthamoeba activities: Odontites linkii subsp. cyprius (Boiss.) Bolliger, Ptilostemon chamaepeuce subsp. cyprius (Greuter) Chrtek & B. Slavík, and Quercus alnifolia Poech. Screening for radical scavenging activity, total phenolic content (TPC), and total flavonoid content (TFC) were performed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABST) methods, Folin–Ciocalteu method, and aluminum chloride method, respectively. An antibacterial-susceptibility test (AST) was performed using a broth microdilution assay to estimate the minimum inhibitory concentration (MIC) using iodonitrotetrazolium chloride (INT). Trypan blue (0.5%) was used to assess in vitro anti-Acanthamoeba cell viability of the ethanolic leaf extracts after 24-, 48-, and 72-h exposure—screening of ethanolic leaf extracts with liquid chromatography–mass spectrometry (LC-MS) for known compounds with biological activity. The ethanolic leaf extract of Odontites linkii subsp. cyprius demonstrated the highest anti-Acanthamoeba activity, with an inhibitory concentration (IC50) of 7.02 mg/mL after 72 h. This extract also showed an in vitro minimum inhibitory concentration (MIC) of 0.625 mg/mL against Enterococcus faecalis, a common nosocomial pathogen. The LC-MS analysis revealed the presence of bioactive iridoid compounds in O. linkii subsp. cyprius, further highlighting its potential as a source for new drug compounds. The ethanolic extract of O. linkii subsp. cyprius demonstrated a dose-dependent and time-dependent anti-Acanthamoeba effect in vitro. This study is the first to report the presence of iridoid compounds and anti-Acanthamoeba activities in the ethanolic extract of O. linkii subsp. cyprius. These promising findings highlight the potential of plant extracts, particularly O. linkii subsp. cyprius, as a source for new drug compounds for Acanthamoeba infections.

The in vivo anti-inflammatory activity was assessed using the carrageenan-induced paw edema model, with diclofenac as the standard. When compared to the standard diclofenac, the ethanolic leaf extract of P. bisulcata showed considerable anti-inflammatory efficacy in a dose dependent manner, resulting in the reduction of paw edema volume. The rats treated with ethanolic leaf extract of 500 mg/kg showed better activity. The research discovers that P. bisulcata has substantial anti-inflammatory action, indicating that it has medicinal potential in the treatment of inflammatory ailments.

Biochemical Studies of Averrhoa carambola Ethanol Leaf and Fruit Extracts on Alloxan-induced Diabetic Rats

The use of herbal medicines has always been an option to treat diseases such as diabetes cancer and other ailments. This study aimed to evaluate the effect of Averrhoa carambola leaf and its fruit ethanol extracts on biochemical parameters and histopathology features. Forty five albino rats were assigned into 9 groups of 5 rats each. Except for the normal control group, others were induced to be diabetic by a single intraperitoneal injection of alloxan. Group 1 (normal control) and Group 2 (diabetic untreated) received water. Group 3 received 2.5mg/kg glibenclamide, Groups 4-9 received graded doses (250mg/kg, 500mg/kg and 750mg/kg) of leaf and fruit extracts of Averrhoa carambola. Treatment lasted 14days. At the end of the treatment, blood samples and organ (pancreas) were collected from the animals for biochemical and histopathological evaluation. Treatment of alloxan-induced diabetic rats significantly (p<0.05) reduced the glucose concentration across all treated groups. Following induction of diabetic mellitus, the serum activities of liver enzymes (Alanine amino transferase, Aspartate aminotransferase and Alkaline phosphatase), low-density lipoprotein cholesterol (LDL-C) and triglyceride were significantly (p<0.05) elevated in diabetic untreated group with corresponding reduction in serum protein, albumin and high-density lipoprotein cholesterol (HDL-C) compared to the normal control and treated groups. However, the fruit extracts exhibited a high increase in urea and creatinine levels especially at dose of 750mg/kg body weight when compared with the leaf though not significantly higher than the diabetic untreated group. From histopathology studies, the groups treated with the leaf extract of Averrhoa carambola showed greater structural improvement and an increase in pancreatic islet cells. Therefore this study showed that although ethanol extracts of Averrhoa carambola leaf and fruit have antidiabetic properties, the leaf extract possesses more antidiabetic effect.

Acrostichum aureum L. (A.aureum) is a medicinal plant that has anti-cancer, anti-inflammatory, and anti-bacterial activities and has been widely used traditionally in the treatment of many diseases. However, there is a dearth of information on the plant's safety. The present investigation was carried out to evaluate the acute and sub-acute toxicity of ethanol leaf extract of A. aureum (ELAA) in female Sprague Dawley (SD) rats. Oral acute toxicity was studied in female SD rats administered a single dose of 5000 mg kg-1 body weight ELAA. The sub-acute toxicity evaluation was also conducted orally with 100, 200, 500, and 750 mg kg-1 body weight of ELAA for 28 days in female SD rats. The impact of sub-acute treatment on body weight, gross histology, relative organ weight, urinalysis, hematology, plasma biochemistry, and histopathology was assessed following treatment. The ELAA did not cause death or signs of toxicity after acute treatment. Similarly, all the parameters evaluated during acute and sub-acute administration of ELAA did not significantly differ from the control. Therefore, the median lethal dose (LD50) of the ethanol extract of Acrostichum aureum is greater than 5000 mg kg-1 body weight. Its oral sub-acute administration is also non-toxic and safe at the tested doses.

Neuroinflammatory Response and Redox-regulation Activity of Hyperoside in Manganese-induced Neurotoxicity Model of Wistar Rats.

Excessive manganese exposure can lead to neurotoxicity with detrimental effects on the brain. Neuroinflammatory responses and redox regulation play pivotal roles in this process. Exploring the impact of hyperoside in a Wistar rat model offers insights into potential neuroprotective strategies against manganese-induced neurotoxicity. The study investigated the neuroprotective efficacy of hyperoside isolated from the ethanol leaf extract of Gongronema latifolium (HELEGL), in the brain tissue of Wistar rats following 15 consecutive days of exposure to 30 mg/L of MnCl2. Control animals in Group 1 had access to regular drinking water, while animals in groups 2-4 were exposed to MnCl2 in their drinking water. Groups 3 and 4 also received additional HELEGL at doses of 100 mg/kg and 200 mg/kg of body weight, respectively. In Group 5, HELEGL at a dose of 100 mg/kg of body weight was administered alone. Treatment with HELEGL commenced on day 8 via oral administration. HELEGL effectively mitigated MnCl2-induced memory impairment, organ-body weight discrepancies, and fluid intake deficits. Exposure to MnCl2 increased the activities or levels of various markers such as acyl peptide hydrolase, tumour necrosis factor-α, dipeptidyl peptidase IV, nitric oxide, IL-1β, prolyl oligopeptidase, caspase-3, myeloperoxidase, H2O2, and malondialdehyde, while it decreased the activities or levels of others, including AChE, BChE, DOPA, serotonin, epinephrine, norepinephrine, GST, GPx, CAT, SOD, GSH, and T-SH (p < 0.05). In contrast, HELEGL effectively counteracted the adverse effects of MnCl2 by alleviating oxidative stress, inflammation, apoptosis, mitochondrial dysfunction, cognitive deficits, and bolstering the antioxidant status. Moreover, HELEGL restored the normal histoarchitecture of the brain, which had been distorted by MnCl2. In summary, HELEGL reversed the causative factors of neurodegenerative diseases induced by MnCl2 exposure, suggesting its potential for further exploration as a prospective therapeutic agent in the management of Alzheimer's disease and related forms of dementia.

Synergistic Phytochemical and Nanotechnological Exploration of Melia azedarach With Silver Nitrate: Elucidating Multifaceted Antimicrobial, Antioxidant, Antidiabetic, and Insecticidal Potentials.

Plants are a rich source of bioactive compounds with significant pharmaceutical and health applications. This study explores the phytochemical, therapeutic, and phytotoxic properties of Melia azedarach by analyzing extracts from its bark, flowers, leaves, and fruits using six solvents: ethanol, methanol, acetone, hexane, chloroform, and distilled water. Twenty-one phytochemical tests were conducted, revealing significantly positive results for various tests. However, the ethanolic and methanolic flower extracts yielded no significant results in other tests. The highest total phenolic content was found in the chloroform extract of the leaves (96 ± 0.01 mg/100 g), and the highest antioxidant activity was observed in the ethanolic and hexane leaf extracts, with a 98% DPPH scavenging rate. Antibacterial testing showed significant efficacy against Serratia marcescens, Bacillus subtilis, Kluyvera spp., and Pseudomonas spp., with p values < 0.0001. The fruit chloroform extract demonstrated the highest alpha-amylase inhibition (93 ± 0.05), while the ethanolic leaf extract had the greatest tumor inhibition (85.6 ± 0.5). Insecticidal assays revealed that the acetone bark extract had the highest control values (56% and 57%). Due to their higher reducing potential, the leaves were used to biosynthesize silver nanoparticles (AgNPs), characterized by UV-Vis spectroscopy, EDX, and SEM, revealing an average particle size of 20-30 nm and spherical morphology. The AgNPs exhibited excellent antibacterial, antioxidant, antidiabetic, and insecticidal activities. These findings highlight the potential of M. azedarach and its AgNPs for developing novel therapeutic agents.

Ethanolic cashew leaf extract: Antifungal activity and its application for shelf-life extension of dried salted tilapia fillets.

Ethanolic cashew leaf extract (ECLE) is rich in phenolic compounds with diverse bioactivities and can serve as a safe natural preservative. This study evaluated the antifungal activity and application of ECLE for shelf-life extension of dried salted tilapia fillets. Several extraction methods, antifungal activity, and application of ECLE in dried salted tilapia fillets were investigated. Ultrasonication followed by the Soxhlet extraction resulted in the highest yield (26.78%), total phenolic content (TPC), and total flavonoid content (TFC) (p<0.05). Conversely, the Soxhlet extraction method rendered lower yield (14.35%), TPC, and TFC (p<0.05). NaCl at high concentrations decreased both TPC and TFC in all ECLE samples, demonstrating the decomposition of those compounds induced by NaCl. ECLE obtained via the Soxhlet extraction method exhibited lower minimum inhibitory concentration (MIC) and minimum fungicidal concentration values than those prepared using other extraction methods. Thus, the former showed higher efficacy in inhibiting fungal growth and reducing mycelium growth than others (p<0.05), despite being less effective than potassium sorbate. At 4MIC, ECLE inhibited mycelium growth (56.83%-78.66%) and spore germination (87.5%-100%) after 72h and 10-16h of treatment, respectively. ECLE (4MIC) could inhibit the toxin production of fungi. For the challenge test, in which ECLE at 400 and 600mg/kg was added to dried salted tilapia fillet inoculated with Aspergillus flavus, fungal growth was retarded over 9 days of storage at 25±2°C (room temperature). Thus, ECEL could act as a natural food preservative to prevent fungal contamination. Toxin from fungi could be avoided, and the quality of dried salted fish was maintained. PRACTICAL APPLICATION: Cashew leaf extract rich in polyphenols can inhibit fungal proliferation, reduce mycelium expansion, prevent spore germination, and limit aflatoxin production. The extract canenhance the safety of dried salted fish, especially when contaminated with Aspergillus flavus in the humid atmosphere (80% relative humidity), particularly for small and medium enterprises. Nevertheless, this extract can also be applied in the fish processing industry, in which the synthetic antifungal agent could be replaced by the natural additive.

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.

This study supports the use of M. scolopendria in ethnomedicinal practice.

The Effectiveness of Fragrant Pandan Leaves Ethanol Extract in Reducing Cholesterol Levels In High-Fat Diet-Induced Rats

Coronary heart disease was the primary cause of death in Asia in 2019. Indonesia is the country with the highest increase in cholesterol levels in Southeast Asia. One of the causes of coronary heart disease is consuming foods high in cholesterol. The commonly given therapy is simvastatin. However, long-term use of simvastatin can cause side effects, so it is necessary to use other alternatives. Pandanus ammaryllifolius also known as fragrant pandan is a plant that is often found in Indonesia and is used in the culinary industry. This study aims to test the effectiveness of fragrant pandan leaves ethanol extract (FPLEE) in reducing cholesterol levels in rats. A total of 30 rats were split into six groups (NC, C+, C-, T1, T2, and T3) and induced on a high-fat diet, except the NC group for 14 days. For the next 14 days, C+ was given a high-fat diet, C- was given simvastatin, T1, T2, and T3 were respectively given FPLEE doses of 8, 16, and 32 mg/200 g BW/day. Next, cholesterol levels were measured. The results of cholesterol levels were tested statistically using One-Way ANOVA and post hoc LSD tests with a = 0.05. There is no substantial difference between NC, C-, and T2. There is a significant difference between T1 and C+ with a higher T1 value. Meanwhile, for T3, there is no significant difference between T3 and NC, C-, and C+. Thus, the most effective dose for reducing cholesterol levels is 16 mg/200 g BW/day.

Control of fungal diseases of tomato (&lt;i&gt;Lycopersicum esculentum&lt;/i&gt; Mill) fruits using various plant extracts

Plant harmful fungi induce symptoms of illnesses that significantly impair the quantity and quality of tomato (Lycopersicum esculentum) yields. The high-water composition of tomatoes renders it highly vulnerable to fungal decay. These fungi, responsible for the decay of tomatoes, generate mycotoxins that pose serious risks to human health. Thus, this research goal is to separate, characterize, and classify the fungi linked with the decline of tomato produce sold across four markets in Mkpat Enin and Ikot Abasi Local Government Areas of Akwa Ibom State, Nigeria. Among the fungal pathogens extracted from afflicted tomato fruits were Fusarium moniliformes, Rhizopus stolonifera, and Aspergillus alternata. Different concentrations of the extracts were individually introduced into Potato Dextrose Agar media. The fungal pathogens were at that point individually introduced into the media and left to incubate for 7 days. Findings revealed that P &lt; 0.05 suppressed the mycelial evolution of the fungal pathogens at a greater concentration tested, with the extent of inhibition varying among different extracts. The results concerning the proportion inhibition of plant extracts on different fungus indicated that, at concentrations ranging from 40% to 80%, ethanolic extracts derived from Cola acuminata and Zingiber officinale significantly (p&lt;0.05) restrained the growth of F. moniliformes, R. stolonifera, and A. alternata. Specifically, the ethanolic leaf extract of C. acuminata demonstrated moderate inhibition on A. alternata at 60%, while the ethanolic extract of Zingiber officinale exhibited low inhibition on F. moniliformes at 40%. At a concentration of 60% in ethanolic extracts, F. moniliformes experienced the greatest inhibition among the plant extracts, whereas A. alternata displayed the least inhibition. Pathogenicity testing indicated that Aspergillus alternata exhibited the largest decay of 25mm in diameter in a healthy tomato fruit, while Rhizopus stolonifera had the smallest decay diameter. Thus, to cover the ledge life of tomato fruits, therefore there’s adequate need to implement proper handling techniques and utilize adequate storage facilities.

Effects of ethanol extract from senna leaf (EESL) on inflammation and oxidative stress in mice: A non-targeted metabolomic study.

Senna leaf is a commonly used medication for treating constipation, and long-term use can cause damage to the intestinal mucosa and lead to drug dependence. But the exact mechanism remains unclear. Using non-targeted metabolomics technology to study the mechanism of senna leaf ethanol extract (EESL) inducing inflammation and oxidative stress in mice and causing side effects. EESL was administered to mice by gavage to detect inflammation and oxidative stressrelated factors in mice, and the EESL components and differential metabolites in mouse plasma were analyzed using non-targeted metabolome techniques. 23 anthraquinone compounds were identified in the EESL, including sennoside and their derivatives. Administration of EESL to mice resulted in a significant increase in pro-inflammatory factors, IL-1β, and IL-6 in the plasma, while the levels of IgA significantly decreased. The levels of oxidative stress significantly increased, and the intestinal mucosal integrity was impaired. 21 endogenous in plasma metabolites were identified as differential metabolites related with taurine and taurine metabolism, glycerophospholipid metabolism, arachidonic acid metabolism, tryptophan metabolism, and sphingolipid metabolism. These metabolic pathways are related to oxidative stress and inflammation. Senna leaf can inhibit the expression of tight junction proteins in the intestinal mucosa and disrupt intestinal mucosal barrier integrity, exacerbating oxidative stress and inflammation induced by bacterial LPS entering the bloodstream. In addition, the impact of Senna leaf on tryptophan metabolism may be linked to the occurrence of drug dependence.
