BACKGROUND
Apium leptophyllum (Pers.) is an annual herb with traditional appreciation for various pharmacological properties; however, the scientific information on this herb is insufficient. The aim of the present investigation was undertaken to evaluate flavonoidal fraction of A. leptophyllum fruit (FFALF) against diarrhoea on albino rats.
METHODS
The antidiarrhoeal study was conducted by castor oil induce diarrhoea, prostaglandin E2 (PGE2) induced enteropooling and intestinal transit by charcoal meal test. The rats were divided into five groups (six/group). Group I served as control and received orally 2% acacia suspension; Group II served as standard and received orally loperamide (3 mg/kg) or atropine sulphate (5 mg/kg); Group III, IV and V served as test groups and received the FFALF at doses of 5, 10 and 20 mg/kg orally, respectively.
RESULTS
In castor oil-induced diarrhoeal model, the FFALF significantly (p < 0.001) reduced the frequency of diarrhoea, defecation and weight of faeces as well as increased the sodium-potassium ATPase (Na+K+ATPase) activity and decreased nitric oxide (NO) content in the small intestine. In prostaglandin induced enteropooling model, it significantly (p < 0.01) and dose dependently slowed the intestinal fluid accumulation by decreasing the masses and volumes of intestinal fluid where as in charcoal meal test, it decreased charcoal meal transit in gastrointestinal tract as compared with control.
CONCLUSIONS
The study reveals that the FFALF possess anti-diarrhoeal properties mediated through inhibition of hyper secretion and gastrointestinal motility which support the traditional use of the plant.
