Effects of Anethum graveolens L. seed extracts on experimental gastric irritation models in mice.

Background: As a folk remedy, Anethum graveolens seed (dill) is used for some gastrointestinal ailments. We aimed to evaluate aqueous and ethanolic extracts of anti-ulcer and acute toxicity effects of the Anethum graveolens in mice.

Results: Gastric mucosal lesions were induced by oral administration of HCl (1 N) and absolute ethanol in mice. The acidity and total acid content of gastric juice were measured in pylorus-ligated mice. LD50 values of the aqueous and ethanolic extracts were 3.04 g/kg, i.p., (1.5, 6.16) and 6.98 g/kg, i.p., (5.69, 8.56), respectively. The efficacy of high dose of extracts (p.o.) was similar to sucralfate. The acidity and total acid content were reduced by the orally or intraperitoneally administration of the extracts.

Conclusions: The results suggest that A. graveolens seed extracts have significant mucosal protective and antisecretory effects of the gastric mucosa in mice.
