Objectives: This study was conducted to investigate the antiemetic, antimicrobial and anti-radical activity of methanolic extracts of Foeniculum vulgare. Â
Materials and Methods: The antiemetic assay was carried out by using chick emetic model with minor modifications by calculating the mean decrease in the number of retching. The antimicrobial activity of the crude extract was performed by Disc Diffusion method. The anti-radical activity was determined by the 2, 2-diphenyl-2-picrylhydrazyl hydrate (DPPH) method.
Results: The anti-emetic activity of Foeniculum vulgare leaves on young chicks revealed that these extracts have a less anti-emetic effect. The group of chicks treated with Chlorpromazine was found to have 60.6 retches as compared to the 66 retches of the control group, thus Chlorpromazine reduced the retches by 7.93%. The chickens treated with leaves extracts inhibited the retches up to 2.03%. The minimum antimicrobial effect was found in this methanol crude extract. The extract did not appear potent in terms of both zones of inhibition and spectrum of activity. In anti-radical activity test, the extract showed moderate free radical scavenging activity with IC50 value 240.39Î¼g/ml. while compared to that of the reference standard ascorbic acid.
Conclusion: Methanolic extract of Foeniculum vulgare leaves have minimum anti-emetic and anti-microbial activities and moderate anti-radical properties.
