In vivo anticoccidial activity and immune response of Moringa oleifera and Vernonia amygdalina leaves against Eimeria magna and Eimeria media in rabbits.

The aims of this study were to determine the immune response and the anticoccidial activity induced by Moringa oleifera and Vernonia amygdalina leaves in rabbits infected with Eimeria magna and Eimeria media. Thirty-five-day-old rabbits, free from coccidia, were infested with 2.103 oocysts of Eimeria magna and Eimeria media, then received the acetone extract of the leaves of Moringa oleifera and Vernonia amygdalina at different doses by oral gavage. The inhibition of the excretion of oocysts was evaluated by the McMaster technique and the levels of cytokines (IL-4 and IL-12) and immunoglobulin IgG were assayed by the ELISA method. The in vivo efficacy on E. magna and E. media oocysts was 95.43% and 96.53% for Moringa oleifera and Vernonia amygdalina at 1000 mg/kg bw against 98% for the positive control. Interestingly the plant extracts increased the production of interleukin (IL) and immunoglobulins (Ig) compared to controls. Plasma IL-4 levels (pg/ml) in rabbits were 128.94 and 131.38; those of IL-12 (pg/ml) were 395.55 and 426.56, and then for those of IgG (μg/ml) were 14.70 and 13.94 respectively with the acetone extracts of Moringa oleifera and Vernonia amygdalina on D14 PT at 1000 mg/kg bw. This study indicates that Moringa oleifera and Vernonia amygdalina can be used as an alternative to synthetic anticoccidials. These plants could be used to increase the resistance of the immune system of rabbits to infestations of Eimeria species in rabbit farms.

Evaluation of Antidiabetic Effect of Combined Leaf and Seed Extracts of Moringa oleifera (Moringaceae) on Alloxan-Induced Diabetes in Mice: A Biochemical and Histological Study.

Moringa oleifera (Moringaceae) is a medicinal plant rich in biologically active compounds. The aim of the present study was to screen M. oleifera methanolic leaf (L) extract, seed (S) extract, and a combined leaf/seed extract (2L : 1S ratio) for antidiabetic and antioxidant activities in mice following administration at a dose level of 500 mg/kg of body weight/day. Diabetes was induced by alloxan administration. Mice were treated with the extracts for 1 and 3 months and compared with the appropriate control. At the end of the study period, the mice were euthanized and pancreas, liver, kidney, and blood samples were collected for the analysis of biochemical parameters and histopathology. The oral administration of the combined L/S extract significantly reduced fasting blood glucose to normal levels compared with L or S extracts individually; moreover, a significant decrease in cholesterol, triglycerides, creatinine, liver enzymes, and oxidant markers was observed, with a concomitant increase in antioxidant biomarkers. Thus, the combined extract has stronger antihyperlipidemic and antioxidant properties than the individual extracts. The histopathological results also support the biochemical parameters, showing recovery of the pancreas, liver, and kidney tissue. The effects of the combined L/S extracts persisted throughout the study period tested. To the best of our knowledge, this is the first study to report on the antidiabetic, antioxidant, and antihyperlipidemic effects of a combined L/S extract of M. oleifera in an alloxan-induced diabetic model in mice. Our results suggest the potential for developing a natural potent antidiabetic drug from M. oleifera; however, clinical studies are required.

Reactive Oxygen Species (ROS) Are Generated as Organic Contaminants Are Broken Down: SnO2-Doped Graphene Oxide Nanocomposites Are Investigated Under Visible Light Illumination for their Photocatalytic Activity

Our aim is to establish a more efficient and reliable method for the bio-fabrication of pure SnO2 and SnO2-doped graphene oxide nanocomposites through a green chelating agent called Moringa Oleifera extract by sol-gel method. A sintered SnO2-doped GO nanocomposite exhibited increased crystallinity and size with increasing temperature, as determined by XRD studies. An FTIR investigation shows that the SnO2-doped GO nanocomposite exhibits two distinct bands at 733 cm−1 and 438 cm−1 due to terminal oxygen vibrations, while samples treated with G-O-Sn-O exhibit bands at 733 cm−1 due to antisymmetric stretching. By increasing the SnO2 peak, SnO2 nanoparticle sizes decrease, which results in a broadened GO, as well as a reduced IR intensity. By SEM and EDAX, the size and morphology of SnO2-doped GO nanocomposites were clearly observed. It was calculated that the optical bandgap of SnO2-doped GO nanostructures is 4.48 eV. It has been demonstrated that SnO2-doped GO nanocomposite can be used as an organic photocatalyst against organic pollutants methyl orange (MO) dye; despite its fast charge recombination when illuminated with visible light, these findings have been reported in detail.

Anti-fatigue properties of the ethanol extract of Moringa oleifera leaves in mice.

Moringa oleifera (M. oleifera) leaves are rich in nutrients and bioactive ingredients. This study was aimed at evaluating the anti-fatigue effect of the ethanol extract of M. oleifera leaves (MLEE) on mice and its primary mechanism of action using a weight-loaded forced swimming test. In the present study, MLEE was prepared by ultrasound-assisted extraction, and its anti-fatigue effect and antioxidant capacity were evaluated in mice. Mice were administrated MLEE (320 mg kg-1 body weight) for 15 days. MLEE supplementation significantly increased levels of glucose and non-esterified fatty acids (NEFA), while decreasing levels of lactate and blood urea nitrogen in serum (P < 0.05); the levels of glycogen in the liver and muscle were also increased, as was the activity of glycogen synthase and the level of NEFA in muscle (P < 0.05). According to a Western blot analysis, MLEE increased the expression of AMPKα1, JNK, AKT and STAT3 in the muscle of mice. Our findings indicate that MLEE has an anti-fatigue effect via the AMPK-linked route, which enables it to control energy metabolism and enhance antioxidant enzyme activity. © 2023 Society of Chemical Industry.

Antibiofilm Effect of Moringa oleifera Leaf Extract Against Staphylococcus aureus, Cytotoxicity, Biochemical aspects, Anti-Inflammatory potential, and Interference on the Activity of Antimicrobial Drugs

Abstract: There is a growing technical difficulty to treat infectious diseases due to molecular mechanisms of resistance to antimicrobial drugs, such as biofilm formation. Here we provide evidence of the antimicrobial potential of the hydroethanolic extract of Moringa oleifera leaves, traditionally used to treat disorders like cardiovascular and endocrine diseases, on clinical isolates of Staphylococcus aureus. The extract was chemically characterized using classic techniques and by ultra performance liquid chromatography (UPLC). We carried out minimum inhibitory concentration tests, as well as minimal bactericidal concentration and minimal biofilm eradication concentration tests. Moreover, we tested the anti-inflammatory potential and assessed the toxicity of the extract on buffalo green monkey (BGM) cells. We also investigated the effects of combining the extract to clinically relevant antimicrobial drugs (i.e., synergistic or antagonistic interactions). The extract was active at 8 g/mL and 16 g/mL for planktonic cells and biofilms, respectively. Its anti-inflammatory potential was confirmed, and it lacked cytotoxicity. No significant interference of the extract on antimicrobial drugs was observed. Flavonoids, tannins, proteins, carbohydrates and vitamin C were detected in the extract. Our data open doors for further studies with isolated molecules of the extract in order to conduct in vivo antimicrobial tests.

Effects of Flavonoids and Phenols from Moringa oleifera Leaf Extracts on Biofilm Processes in Xanthomonas campestris pv. campestris.

Xanthomonas campestris pv. campestris is the causal agent of black rot in crucifers, a plant disease with significant economic impact. Xanthomonadaceae is a large family of Gram-negative bacteria that cause symptoms by blocking water flow in plants by invading the xylem. To accomplish this, the main mechanism the bacteria use to adapt to environmental changes and colonize tissues is biofilm formation. In recent years, growing interest in natural antimicrobial compounds has led to the study of different phytocomplexes derived from plants. In this work, Moringa oleifera was selected, as its leaves are rich in phenols, essential oils, and vitamins that exert antibacterial activity. X. campestris pv. campestris biofilm, one of its major virulence factors, was studied. Biofilm formation and removal were analyzed on abiotic and biotic surfaces with and without M. oleifera leaf extracts. The data from the analysis show that Moringa oleifera leaf extracts and single phenols were able to inhibit biofilm growth on abiotic surfaces, but the activity of the whole phytocomplex was significantly higher compared to that of individual phenols. The effect of Moringa oleifera extracts on cabbage leaves in vivo was also found to be very important, as scanning electron microscopy showed that treatment with the extracts led to clear unblocking of the xylem, implying many advantages for use in black rot control.
