Introduction. Parsley (Petroselinum crispum) is used in the traditional herbal medicine to treat intestinal disorders. The aim of this study was to examine the effect of aqueous and ethanol extracts of parsley on spontaneous and acetylcholine induced contractions on isolated rat ileum. Material and methods. Wistar albino rats (250-300g) were used in this study. The ileum portions were isolated out and cleaned off mesenteries. Preparations 2 cm long were mounted in 20 ml tissue baths containing Tyrode's solution maintained at 37?C and aerated with a mixture of 5% carbon dioxide in oxygen. In the first part of experiments, contractile responses to the aqueous (ethanol) extracts of parsley were recorded. In the second part, increasing concentrations of acetylcholine were added to the organ bath for a full concentration response curve and then concentration response curves were obtained after adding the aqueous (ethanol) extracts of parsley. Results and discussion. Our results showed that aqueous (62.22?7.15%) and ethanol (79.16?9.34%) extracts of parsley in dose dependent manner decreased the tonus of spontaneous contractions of isolated rat ileum. The aqueous (32.16?2.75%) and ethanol (53.96?4.86%) extracts of parsley reduced the acetylcholine induced contraction, the reduction was greater with ethanol extract than with the aqueous one. Conclusion. It can be concluded that the aqueous and ethanol extracts of parsley exert antispasmodic activity on rat ileum. The relaxant effect of ethanol extract was better comparing to aqueous extract of parsley.

Objective: The purpose of this study was to investigate the relaxative effects of blackcurrant juice on the gastrointestinal smooth muscle in vitro. Materials and Methods: Berries of the blackcurrant cultivar Ometa were used for the preparation of the juice used. The spasmolytic activity of blackcurrant juice was tested on rat ileum isolated from male Wistar rats by monitoring its influence on spontaneous contractions, as well as contractions induced by potassium chloride (KCl), barium chloride (BaCl2), calcium chloride (CaCl2), and acetylcholine (Ach). The results are expressed as the mean ± standard deviation obtained in 6 measurements and statistical significance was determined by the Student t test, with p < 0.05 taken as significant. Results: The blackcurrant cultivar Ometa significantly reduced the frequency and the amplitude of spontaneous contractions (57.94 ± 3.44%) and Ach-induced contractions (42.74 ± 5.36%; p < 0.05) of the isolated rat ileum. Cumulative concentrations (0.01–3 mg/mL) of the Ometa juice also reduced contractions of the isolated rat ileum stimulated by KCl (51.46 ± 6.87%), CaCl2 (57.54 ± 6.47%), and BaCl2 (58.54 ± 10.55%). The inhibitory effects of the juice were proportional to the applied concentration. Conclusion: The antispasmodic effect of Ometa cultivar shows that common gastrointestinal disorders could be treated by the functional food.

Abstract Cinnamomum tamala and Cinnamomum verum are known for their folk medicinal usage in treating gastrointestinal ailments. The spasmolytic activity of essential oils was studied using isolated rat ileum. The results indicate that C. tamala, despite having a lower content of eugenol (60%), shows a spasmolytic potential of 68.01 ± 2.63% (EC50 = 110.12 ± 13.58 μg/mL) while C. verum with rich eugenol (80%) shows lesser spasmolytic potential (38.96 ± 0.63%) and fails to attain an EC50 value. Upon comparison with standard eugenol’s percentage of spasmolytic (35.68 ± 2.57%), it is evident that the action of these essential oils does not solely rely on the major component but the synergistic role in association with other components of the mixture influences the pharmacological action of the essential oils. In silico docking of phytochemicals of leaf essential oils with M2 (M2AChR) and M3 muscarinic (M3AChR) and nicotinic acetylcholine receptor (nAChR) was carried out to determine the type of receptors through which the essential oils had spasmolytic potential. The binding affinity for eugenol with nAChR shows a better docking score than M2AChR and M3AChR.

Both methionine- and leucine-enkephalin caused the isolated rat ileum to relax in a concentration-dependent manner; the EC50 values were in the order of 10−8 to 10−7 M. This isolated preparation was generally not sensitive to morphine. The enkephalin-induced inhibitions were not blocked by the classical narcotic antagonist, naloxone.
