Evaluation of the antidiarrheal activity of 80% methanol extract and solvent fractions of the leaf of Bersama abyssinica fresen (Melianthaceae) in mice

Introduction The use of traditional medicinal plants in the management of diarrhea has long been practiced in Ethiopia. B. abyssinica fresen is one of the plants traditionally used to treat diarrhea whereas an in vivo study had not yet been conducted. Thus, this study aimed to evaluate the antidiarrheal activity of crude extract and solvent fractions of the leaf of B. abyssinica in mice. Methods Cold maceration within 80% methanol was used to extract the leaf powder and extract of the leaf was fractionated using n-hexane, chloroform, and distilled water. The in vivo antidiarrheal activity of crude extracts and solvent fractions were tested in experimental models of castor oil-induced diarrhea, enteropooling, and antimotility test. Five groups each with 6 mice were used under the three antidiarrheal models. Positive controls were treated with loperamide 3 mg/kg and atropine 5 mg/kg and 2% tween 80 was used in the treatment of negative controls. The extract and solvent fractions were administered at doses of 100, 200, and 400 mg/kg. Time of onset of diarrhea, number and weight of total and wet feces, the percent reduction in the number of wet feces, weight and volume of intestinal contents, and percent inhibition of intestinal motility were recorded. Data were analyzed using SPSS version 20. Result Defecation of castor oil-induced diarrheal or loose stools was inhibited (p < 0.01 to p < 0.001) at 200 mg/kg and 400 mg/kg of crude extract and aqueous fraction. The crude extract and the aqueous fraction at three doses (p < 0.01 to p < 0.001), the chloroform fraction at 200 mg/kg and 400 mg/kg (p < 0.01 to p < 0.001), and the n-hexane fraction at 400 mg/kg (p < 0.05) reduced intraluminal fluid accumulation compared with the negative control. Castor oil-induced intestinal motility was significantly suppressed with the three-doses of aqueous fraction (p < 0.05 to p < 0.001), 200 mg/kg and 400 mg/kg of crude extract (p < 0.05 to p < 0.01), 400 mg/kg of chloroform and n-hexane (p < 0.01 to p < 0.001) compared with negative control. Conclusion The crude extract, aqueous, and chloroform fractions of B. abyyssinica leaves have promising anti-diarrheal effects, supporting the plant's traditional use to treat diarrhea.

ANTIDIARRHEAL ACTIVITY TEST OF ETHANOLIC EXTRACT OF WHITE POMEGRANATE PEEL (PUNICA GRANATUM L.) IN MALE WHITE MICE (MUS MUSCULUS), SWISS WEBSTER LINE USING THE INTESTINAL TRANSIT METHOD

Objective: Diarrheal disease and its complications remain a major cause of morbidity and mortality in children, especially in developing countries. It is usually a symptom of an infection in the intestinal tract, which can be caused by a variety of bacterial, viral, parasitic or organisms. The purpose of this study was to determine the activity and dose of white pomegranate peel (Punica granatum L.) ethanol extract as an antidiarrheal in white male mice using the intestinal transit method. Methods: Mice were grouped into 5 groups: negative control (Na CMC 1 %), positive control (loperamide HCl 0.0104 mg/20 g mice BW), and pomegranate peel ethanol extract test group 1, 2, and 3 (dose of 16, 32, and 64 mg/20 g mice BW). The length of the intestine that the ink marker traversed from the pylorus to the end (which is black) was measured using a ruler. Results: Based on statistical analysis, there were significant differences between all groups (<0.05). The highest antidiarrheal activity was in the ethanolic extract of pomegranate peel at a dose of 64 mg/20 g mice BW with an inhibition percentage of 36.44% and higher than the positive control (29.81%). The inhibition percentage was also resulted by dose 1 and 2 (12.46% and 29.53%, respectively). Conclusion: From these results show a correlation that the higher the extract dose, the higher the antidiarrheal potential.

Evaluation of Antidiarrheal Activity of 80% Methanolic Extract of the Leaves of Cordia africana (Lamiaceae) in Mice

Background. Diarrheal disease is a major cause of morbidity and mortality throughout the world, particularly in developing countries. Currently available drugs are linked with adverse effects, contraindications, and risk of resistance. Traditionally, the leaf concoction of Cordia africana is claimed to be used for diarrhea. However, the safety and efficacy of the leaf extract have not been scientifically approved yet. Therefore, the study was conducted to validate its antidiarrheal activity and safety profile in mice. Method. The hydromethanolic extract was obtained by the cold maceration technique in 80% methanol. Phytochemical screening tests were done for secondary metabolites by using standard tests. The antidiarrheal activity of the test extract at the doses of 100, 200, and 400 mg/kg was evaluated by using castor oil-induced diarrheal, gastrointestinal transit, and enteropooling models in mice. Result. In an acute toxicity study, there were no visible signs of toxicity and mortality following a single oral administration of 2000 mg/kg. Phytochemical screening tests revealed the presence of alkaloids, saponins, flavonoids, terpenoids, phenols, and tannins. The hydromethanolic extract significantly prolonged the onset of diarrhea and reduced the weight of wet and total feces at 100 ( P < 0.01 ), 200 ( P < 0.001 ), and 400 mg/kg ( P < 0.001 ) in the castor oil-induced diarrheal model. However, in the gastrointestinal transit model, a significant ( P < 0.001 ) reduction in the charcoal meal travel was observed in the middle (200 mg/kg) and higher (400 mg/kg) test doses. Similarly, the extract produced a significant ( P < 0.001 ) reduction in the weight and volume of intestinal contents at the aforementioned doses. Conclusion. The study demonstrated that the test extract showed promising antidiarrheal activity. Hence, this study supports its antidiarrheal use in Ethiopian folklore medicine.

Antidiarrheal activity of Bridelia ferruginea bark methanolic extract involves modulation ATPases in mice and inhibition of muscarinic acetylcholine receptor (M3) and prostaglandin E2 receptor 3 (EP3) in silico

Objectives Diarrhea, an abnormal state in which the individual has about three or more daily bowel movements, is now considered one of the most challenging global public health problems. Using plant products, such as Bridelia ferruginea is an alternative treatment option. The objective of this study was to investigate the antidiarrheal activity of B. ferruginea bark methanolic extract (BfME) and the mechanisms involved. Methods BfME antidiarrheal activity was evaluated in mice model of castor oil-induced diarrhea and enteropooling. To evaluate motility, gastrointestinal transit time was carried out using phenol red meal, while intestinal activities of selected ATPases were also evaluated. Furthermore, the active components in BfME were detected by GC-MS analysis, while molecular docking of the most abundant compounds with muscarinic acetylcholine receptor (M3) and prostaglandin E2 receptor 3 (EP3) were conducted. Results BfME at 400 and 800 mg/kg showed antidiarrheal activity by delaying onset of diarrhea, reduced gastrointestinal transit and increased intestinal activities of Na+ K+-ATPase, Ca2+ Mg2+-ATPase and Mg2+-ATPase. Molecular docking revealed that γ-sitosterol, α-amyrin, and stigmasterol have outstanding binding affinity for M3 and EP3. Conclusions In view of these results, the observed antidiarrheal activity possibly occurs via the activation of ATPases activities and inhibition of M3 and EP3.

Antidiarrheal Activity of Four Different Species of Litsea Available in Bangladesh

The objective of the present study includes the evaluation of the antidiarrheal properties of the methanol extracts of Litsea deccanensis Gamble (MELD) bark, Litsealancifolia (Roxb.) Hook. f. MELL),Litseaglutinosa Gamble (MELG) and Litsea monopetala Roxb. (MELM) leavesin Swiss albino mice. The antidiarrheal activity was evaluated by measuring percentage inhibition of diarrheal feces, total fecal output, gastrointestinal motility and by using peristaltic indices. Castor oil was used to induce diarrhea in the experimental animal. The experiments were carried out by using three different doses (100, 200, and 400 mg/kg body weight) of these four plant extracts. The number of wet feces and total weight of the feces were significantly (p < 0.05) and dose-dependently reduced by all the plant extracts and this effect was comparable with standard drug. MELD, MELL, MELG and MELM extracts at dose of 400 mg/kg body weight demonstrated diarrheal inhibition by 43.55%, 45.16%, 32.26% and 41.94%, respectively while it was 98.39% for the standard loperamide. Percentage (%) of fecal output for MELD, MELL, MELG and MELM extracts at the dose of 400 mg/kg were 40.14%, 62.27%, 64.06%, 46.26%, respectively.The gastrointestinal motility induced by castor oil was also reduced noticeably (p < 0.05) by all the plant extracts with the increasing doses. The percentage inhibition of gastrointestinal motility at the dose of 400 mg/kg were 26.26%, 33.22%, 32.36% and 22.52% for the MELD, MELL, MELG and MELM extracts respectively, while it was 27.56% for loperamide. In most cases, all the plant extracts can reduce the peristaltic indices which were comparable to control. The obtained results from this study revealed that the methanol extracts of four different species of Litsea found in Bangladesh may have antidiarrheal potential. It also provides the basis for the traditional use of these plants to treat diarrhea.

In vitro carminative and in vivo antidiarrheal activity of Citrus maxima

In this study, the methanolic extracts of leaves of Citrus maxima were evaluated for their carminative and antidiarrheal activities. By soxhlet method, the methanolic extract of leaves of Citrus maxima was prepared. Carminative activity of methanolic extract was studied in vitro by acid-base titration technique and antidiarrheal activity was studied in rats by castor oil induced diarrhoea method. The phytochemical screening was done using various chemical tests. Alkaloids, tannins, carbohydrates, flavonoids, terpenoids, amino acids, anthraquinones, glycosides are confirmed to be present in the leaf. Carminative activity of extract was found significantly less with 5mL, when compared with 10mL extract. The antidiarrheal activity observed in the animals treated with 200mg/kg showed significant activity compared with the animals treated with 100mg/kg. The study revealed that carminative activity and antidiarrheal activity of methanolic extract of C. maxima. May be the extract acts on circular and longitudinal intestinal muscle by inhibiting acetylcholine and prostaglandins, which reduces peristaltic movements and prolongs transmit time, reduces fecal volume, increases viscosity and viscous fluid and electrolyte loss. The compound in the extract causes mild irritation resulting in vasodilation of gastrointestinal muscles, thereby relieving cramping and expels gas
