Studies on the anthelmintic activity of Tagetus patula on common poultry worms Ascaridia galli and Heterakis gallinae

Abstract

Fresh petals of T. patula locally known as “Genda” was dired in shade and grind to obtain fine powder. This
powder is subjected to extraction in soxhlet apparatus using alcohol as solvent for 20-24 hrs. The greasy mass
obtained after the coplete removal of solvent is diluted to prepare different concentration i.e. 2%, 4% and 6%
and tested for in vitro anthelmintic activity. 2% extract caused mortality in A. galli after an exposure of 12 hrs.
and in H. gallinae after 10 hrs. At 6% concentration mortality was observed after 8 and 7 hrs. respectively in
A. galli and H. gallinae. The effect of the extract was also examined on glucose uptake, glycogen contents, lactic
acid production, acid and alkaline phosphomonoesterases and cholinesterase activity to find out the possible
mode of action of the extract.
