Chemicals used were: Acetylcholine chloryste (Fluka AG), Barium chloride (Fluka AG), Atropine (Fluka AG ), Alverine (Sigma).
The antispasmodic activity of methanol, ethyl acetate and chloroform extracts and pure compounds, Bakkenolide and reference drug Alverine, were studied against two spasmogenic substances: acetylcholine (Ach) and barium chloride (Ba[Cl.

The extracts and substances were allowed to act on the preparations for 5 min, and afterwards the agonists such as barium chloride were cumulatively added and were allowed to reach a steady state at each concentration.
