Cola nitida has been used in traditional medicine to treat diverse ailments including diarrhea. This study is carried out to investigate the antidiarrheal activity of the ethanol and chloroform seed extract of Cola nitida in Wistar albino rats. The ethanol and chloroform extracts of Cola nitida were evaluated with different doses (100mg/kg, 300mg/kg and 650mg/kg of animal weight) orally for antidiarrheal activity using castor oil induced-diarrhea, gastrointestinal motility test and castor oil-induced gastroenteropooling in Wistar albino rats. The observed activity was compared to standard antidiarrheal drug Lopermaide hydrochloride (2mg/kg) and to distilled water (10ml/kg) which served as the negative control. Cola nitida ethanol extract at 150, 300 and 650mg/kg showed 55.64%, 59.73%, and 71.34% inhibition in gastrointestinal motility respectively. A significant reduction in diarrheal episodes (p<0.0001) was also observed with 650mg/kg of both extracts showing 100% inhibition. A reduction in the volume of fluid in the small intestine was also seen, this was however not significant. The chloroform extract of Cola nitida on the other hand produced a significant reduction in volume and weight of small intestinal content (p<0.05) with 650mg/kg showing a 92.73% inhibition of intestinal fluid accumulation. The ethanol and chloroform extract of Cola nitida showed anti-diarrheal activity in animal model by decreasing the frequency of defecation and by reducing gastrointestinal motility and intraluminal fluid accumulation in the intestine.
Peer Review History:
UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
