Diarrhoea is a public health problem in developing countries. It is therefore important to identify plants with antidiarrhoeal activity. Melochia corchorifolia and Glochidion thomsonii have been used in folk medicine to alleviate several diseases. The present study was performed to investigate the anti-diarrheal properties of ethanolic extract of M. corchorifolia whole plant and G. thomsonii bark. Anti-diarrheal potential was evaluated using castor oil and MgSO4 induced diarrhea, GI motility test as well as castor oil induced enteropooling assay in mice. Extracts were used at 250 and 500 mg/kg per orally. Loperamide (10 mg/kg p.o) was used as standard drug. The ethanolic crude extracts exhibited statistically significant and dose-dependent (250 and 500 mg/kg) anti-diarrheal effect against the total number of episodes of defecation as well as diarrheal feces. In animals pretreated with MC and GT extract showed 42.53% (p<0.05) and 53.13% (p<0.001) protection at a dose of 250 mg/kg and 89.40% (p<0.001)and 57.47% (p<0.001) protection at 500 mg/kg against castor oil induced diarrhea. The MC extract at 500 mg/kg exhibited significant (p<0.05) inhibition of diarrhea (51.04%) in MgSO4 induced diarrhea. In BaSO4 induced GI motility test both the extracts inhibited GI motility and GT at 500 mg/kg dose 38.77% which was highly significant (p<0.01). In the Castor oil induced enteropooling assay MC 250 and 500 mg/kg and GT 250 and 500 mg/kg reduced the intestinal fluid accumulation by 27.42% and 48.39% (p<0.01) and 38.71% (p<0.05) and 51.61% (p<0.01), respectively. The results suggested that both the extracts possessed significant antidiarrhoeal properties which was comparable with standard drug, loperamide and further studies are required to evaluate these effects and the potential of the plant.

BACKGROUND:Skeletal muscle relaxants are drugs that are used to relax and diminish tightness in muscles. Many medicinal plants have known to have skeletal muscle relaxant activity. In past studies some Polyherbal formulation containing Ashwagandha as one of the ingredients and its fat extract have shown to have skeletal muscle relaxant activity in experimental animal models. This study is intended to evaluate the skeletal muscle relaxant activity of alcoholic extracts of Withania Somnifera (Ashwagandha) roots in albino mice, as the literature regarding this extract is scarce. METHODOLOGY: Standard drug (diazepam), different doses of Alcohol extract of ashwagandha (50,100, 150 mg/kg) were given orally to mice and muscle relaxant activity was assessed by Rota-rod apparatus. The fall off time from the rotating rod was noted for each group after 1 hour of drug administration. The difference in fall off time among the standard drug and treated mice was taken as an index of muscle relaxation. RESULTS:The test extract at its different doses showed highly signicant reduction in the time spent by the animals on revolving rod in rotarod test when compared to baseline (p < 0.0001) which is highly signicant. On comparison with diazepam, different doses of Alcohol extract showed weak relaxant activity. CONCLUSIONS : The three different doses of Alcoholic extract showed a dose dependent rise in muscle relaxant action. The results are promising for further investigation of efcient skeletal muscle relaxant activity.

Background: To evaluate the anti-convulsant activity of ethanolic extract of Moringa oleifera (Drum stick leaves) in seizure induced albino mice and to compare it with standard drug Sodium valproate.Methods: Swiss albino mice of either sex weighing around 25-30g were randomly selected and divided into four groups of six mice each. Group 1: control- treated with gum acacia. Group 2: Standard - Valproic acid 40mg/kg body weight. Group 3: T1- ethanolic extract of Moringa oleifera (150mg/kg). Group 4: T2 - ethanolic extract of Moringa oleifera (300mg/kg). All drugs were administered orally one hour prior to induction of seizure. The anticonvulsant activity was screened using maximal electroshock seizure (MES) model and pentylenetetrazole (PTZ) model.Results: Results were analysed by ANOVA followed by Bonferroni’s post hoc test. Abolition of Tonic hind limb extension was taken as the protective end point against MES induced seizures and prolongation of seizure latency in PTZ model.At both the doses the ethanolic extract of Moringa oleifera significantly (p value <0.05) reduced the duration of hind limb extension in MES test and also significantly (p value <0.05) delayed the onset of clonic seizures in PTZ induced convulsion when compared with control group.Conclusions: On comparing the percentage protection offered by Moringa oleifera leaves against both MES and PTZ model, it possesses significant anticonvulsant activity at both doses, with more efficacy at 300mg/kg BW indicating that the test drug can prove a very promising drug for treatment of epilepsy. Further studies are required for isolation and identification of the active constituent.

Background: The objective of this research was to see whether the ethanolic extract of Justicia quinqueangularis leaves had antioxidant and hepatoprotective properties against paracetamol (PCT), ethanol (ETN), and isoniazid and rifampicin (IR)-induced hepatotoxicity in Albino Wistar rats. Methods: The leaves of Justicia quinqueangularis were dried in the shade at room temperature, pulverised, and extracted by soxhlet using ethanol. Quantitative phytochemical experiments were carried out as a first step. The ethanol extract's hepatoprotective activity was evaluated in Albino Wistar rats. PCT (3 g/kg), ETN (5 g/kg), and IR (100 mg/kg) reduced the levels of serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) and bilirubin, which are all biochemical indicators of liver injury. Both hepatotoxin-treated and untreated group of animals determined for their antioxidant levels. SGOT, SGPT, ALP, bilirubin, antioxidant function of DPPH (2,2-diphenyl-1-picrylhydrazyl), hydrogen peroxide (H2O2), lipid peroxidation methods, hydroxyl radicals, and nitric oxide scavenging activities were among the biochemical and histopathological tests performed. Results: The altered levels of biochemical markers were restored to near normal levels in a dose-dependent fashion after treatment with J. quinqueangularis ethanol leaf extract (100 mg / kg, 200 mg / kg, and 400 mg / kg body weight). Conclusion: The findings of the current research indicated that the ethanol leaf extract of J. quinqueangularis had potent antioxidant and hepatoprotective properties against standard drug.
