Introduction: The plant Combretum hypopilinum has many medicinal uses in Africa. Infusion of fresh or dry leaves are commonly taken as cholagogic, diuretic, and purgative and also to treat gastrointestinal disorders, including diarrhoea, dysentery, and stomach achesObjective: To carry out phytochemical and antidiarrheal studies on the methanol stembark extract of C. hypopilinum.Methods: The C. hypopilinum stembark (1kg) were extracted with methanol using cold maceration method for 9 days. The solvent was removed by rotary evaporator and the extract was partitioned with n-hexane, chloroform and ethyl acetate to give the n-hexane, chloroform, and ethyl acetate fractions respectively. The extract was subjected to preliminary phytochemical screening, acute toxicity study and antidiarrheal activity using animal models.Result: The following metabolites: carbohydrates, alkaloids, phenol, steroids, terpenes, saponins, flavonoids and tannins were revealed when the phytochemical screening of the plant extract was carried out. The oral median lethal dose (LD50) of crude extract in mice and rats was estimated to be above 5000 mg/kg. The antidiarrheal activity carried out at dose 150, 300 and 600 mg/bw i.p. using castor oil induced diarrheal, gastric-transit time and anti-enteropooling tests in mice and rats. The extract significantly (P<0.05) inhibited diarrheal in mice and rats with highest protection/ inhibition of 93.1% and 87.9% at doses of 600 and 300 mg/kg (dose dependently) which compared with atropine sulphate (86.2%) respectively, in the castor-oil induced diarrheal test in mice. The extract also significantly (P<0.05) inhibited diarrheal in charcoal meal test with the highest % protection of 24.38% at dose 600 mg/kg and compared with loperamide (28.80%). The anti-enteropooling test in rats showed 68% inhibition of diarrheal as compared to atropine sulphate with 78% inhibition.Conclusion: The results indicated that the methanol stembark extract of Combretum hypopilinum possesses significant dose dependant antidiarrheal activity (p<0.05) in all the antidiarrheal tests. Thus, the traditional use of the plant for the treatment of diarrheal is highly justified in this study.

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.

Different parts of Vitellaria paradoxa plant have many applications in ethno-medicine. Some of the uses of this plant include treatment of diarrhoea and other GIT disorders. In this study the antidiarrhoeal activity of the ethanol extract of Vitellaria paradoxa was evaluated using three experimental models: Castor oil-induced diarrhoea; small intestinal motility and intestinal fluid accumulation (enteropooling) models in mice. Five groups of five mice were used for each model. Group one mice received 10 ml/kg of distilled water, while groups 2, 3, and 4 received 125, 250 and 500 mg/kg of the extract orally respectively. Group 5 mice received Loperamide 5 mg/kg orally. Oral median lethal dose (LD50) of the extract was determined using OECD (2008) Guideline 425. Phytochemical studies were conducted using standard procedures. The LD50 was estimated to be greater than 5000 mg/kg body weight and there were no signs of mortality or visible signs of toxicity in all the mice treated. Phytochemical screening revealed the presence of carbohydrates, alkaloids, flavonoids, saponins, tannins, triterpenes, steroids, cardiac glycosides and anthraquinones glycosides. Extract showed a dose-dependent anti-diarrhoeal activity by reducing stool frequency and consistency. The extract at the higher doses significantly (p < 0.05) inhibited GIT motility and castor oil-induced enteropooling, comparable to that of the reference control drug Loperamide. The study showed that ethanol stem bark extract of Vitellaria paradoxa possess anti-diarrhoeal activity and thus justifies its ethno-medicinal use in the treatment of diarrhoea.

Background: The aqueous extract of Mangifera indica leaves (AEMIL) has been substantiated for its antidiarrhoeal activity without information on the antidiarrhoeal-rich solvent fraction.Aim: This study evaluated the antidiarrhoeal activity of solvent–solvent fractions from M. indica leaves in female Wistar rats.Setting: This is laboratory animal-based phytopharmacological investigation conducted at the University of Ilorin.Methods: Aqueous extract of M. indica leaves was successfully fractionated to give ethyl acetate fraction (EAF), n-butanol fraction (NBF) and aqueous residual fraction (ARF). The fractions at 25, 50 and 100 mg/kg body weight (bw) were screened for antidiarrhoeal activity. The antidiarrhoeal index (ADI) was also computed.Results: Ethyl acetate fraction, NBF and ARF significantly (p 0.05) extended the onset of diarrhoea, reduced fecal parameters (number, weight and water content of feaces and number of diarrhoeal feaces), masses and volumes of intestinal fluid, distance covered by charcoal meal, peristaltic index and its inhibition, with ARF exhibiting the most pronounced effects. The ADI at 25 and 100 mg/kg bw (equivalent doses of 14.09 and 56.3 mg/kg bw, respectively) of ARF which were 55.19 and 49.87, respectively were similar to 48.50 produced by loperamide/atropine sulphate. The ADI of 32.36 and 10.18 for 100 mg/kg bw each (equivalent of 26.41 and 17.24 mg/kg bw) of EAF and NBF respectively, were lower than that of loperamide/atropine sulphate (48.50).Conclusion: Of all the fractions, the 25 mg/kg bw of ARF produced the most profound antidiarrhoeal activity via anti-motility and anti-secretory mechanisms.

Punica granatum (Family: Punicaceae) is a widely consumed fruit in Bangladesh locally known as Anar or Bedana. Traditionally the plant is used to treat diarrhoea, dysentery, hemorrhage, tuberculosis and chronic periodontitis. The present study was undertaken in order to justify and authenticate the traditional use of rind of P. granatum fruit in diarrhoea. Methanolic extract of the rind of the fruit was tested in castor oil- and magnesium sulfate-induced diarrhoea in mice at the doses of 200 and 400 mg/kg body weight. The results of the present study revealed significant antidiarrhoeal activity (p<0.001) in both animal models. The extract inhibited 31.25% defaecation at the dose of 200 mg/kg and 53.75% at the dose of 400 mg/kg in castor oil-induced diarrhoea while standard drug loperamide inhibited 71.25% defaecation. In magnesium sulfate-induced diarrhoea the inhibition of defaecation was 45.71 and 57.14% at the doses of 200 and 400 mg/kg respectively while loperamide inhibited 64.29% defaecation. The antidiarrhoeal effect of the extract was concentration dependent in both castor oil-induced diarrhoea and magnesium sulfate-induced diarrhoea. Phytochemical screening of the extract revealed the presence of flavonoids and alkaloids that may play key role in its antidiarrhoeal activity. The results of the present study validate the folkloric use of the rind of P. granatum in the treatment of diarrhoea.DOI: http://dx.doi.org/10.3329/icpj.v2i5.14437 International Current Pharmaceutical Journal, April 2013, 2(5): 101-104

Background of the Study. As a widely used traditional medicine, Galla Chinensis is rich in tannins. However, there are few detailed studies about pharmaceutical preparations of Galla Chinensis tannin extract (GTE). In the present experiments, for better application and to investigate the possibility that Galla Chinensis tannin extract can be used as an antidiarrheal drug, we prepared Galla Chinensis oral solution (GOS). Materials and Methods. GOS was prepared with GTE, and its physicochemical and microbiological stability was evaluated. The oral acute toxicity of GOS was calculated by the 50% lethal dose (LD50). The antidiarrheal activity was determined in a castor oil-induced diarrhea model in mice through diarrhea symptoms, fluid accumulation ratio, and percentage of distance moved by charcoal meal. Results. The tannin content of GTE was 47.75%. GOS could endure a high temperature without a significant decrease of tannin content. After storage for six months, the tannin content of GOS was still more than 90%. GOS was determined to be nontoxic. Meanwhile, GOS showed significant antidiarrheal activity in a castor oil-induced diarrhea model in mice (P<0.01). Conclusion. The results suggested that GOS is an effective and stable antidiarrheal drug that can be used to complement other therapies.

Background. Hagenia abyssinica is one of the most commonly used medicinal plants for the treatment of diarrhea in Ethiopia. Therefore, this study aimed to evaluate the antidiarrheal effect of methanol crude extract of H. abyssinica leaves in mice. Methods. Acute toxicity testing was conducted using Organization for Economic Cooperation and Development guidelines. The antidiarrheal activity of the crude extract of H. abyssinica was investigated using three animal models such as small intestine transit, enteropooling, and castor oil-induced diarrhea models. The extract was administered at three different doses (100, 200, and 400 mg/kg) to the test groups, while the positive control group received 3 mg/kg of loperamide and the negative control group received 10 ml/kg of vehicle (distilled water). Results. The crude extract of H. abyssinica did not exhibit death at the limit dose (2 g/kg) throughout the observation period. In the castor oil-induced model, the crude extract at a dose of 200 and 400 mg/kg exhibited a significant ( P < 0.05 ) antimotility effect as compared to the negative control. The crude extract revealed a significant reduction in the volume and weight of intestinal contents at 200 and 400 mg/kg doses of the extract. Moreover, the highest antidiarrheal index (ADI) was obtained with the dose of 400 mg/kg of crude extract, which was comparable to the standard drug. Conclusion. The crude extract of Hagenia abyssinica possesses antidiarrheal activity and supports the traditional use of H. abyssinica for the management of diarrhea.

Valeriana hardwickiiis indigenous to Pakistan, Burma and Ceylon, where it is traditionally being used as an antispasmodic and antidiarrheal, besides its culinary use as spice. The aim of this paper was to provide pharmacological validation to these medicinal uses. The crude aqueous-methanolic extract ofValeriana hardwickiirhizome (Vh.Cr) was studied on isolated rabbit jejunum and castor oil-induced diarrhea in mice for spasmolytic and antidiarrheal properties, respectively. Vh.Cr caused concentration-dependent (0.01–1 mg/mL) relaxation of spontaneous contractions in isolated rabbit jejunum and inhibited K+-induced contractions (0.01–0.3 mg/mL), similar to verapamil, suggestive of calcium channel blockade (CCB). The CCB effect was confirmed when pretreatment of the jejunum preparations with Vh.Cr produced a concentration-dependent (0.03–0.1 mg/mL) rightward shift in the Ca++concentration-response curves, as caused by verapamil. Vh.Cr exhibited dose-dependent (100–300 mg/kg) protection against castor oil-induced diarrhea in mice. Loperamide, a standard antidiarrheal drug, similarly prevented the diarrhea. These data indicate the presence of CCB effect in the extract ofValeriana hardwickiirhizome, possibly mediating its antispasmodic and antidiarrheal activities and provide a scientific base for its traditional use in hyperactive gut disorders.

Abstract 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.
