The concentration-dependent inhibitory effect of the petroleum ether (Pet.EH) (a-b), chloroform (CHCl3.EH) (c-d), ethyl acetate (Et.Ac.EH) (e-f) and aqueous (Aq.EH) (g-h) fraction of E. hirta against spontaneous [(in absence and presence of atropine, (0.1 μM)], low K+ (20 mM) and high K+ (80 mM)-induced contractions on rabbit jejunum. The data shown as mean ± S.E.M, n = 4–6 individual experiments using tissues of 4 to 5 different animals
