Gastrointestinal Motility and Acute Toxicity of Pistagremic Acid Isolated from the Galls of Pistacia integerrima

Abstract

© 2017 Bentham Science Publishers. Background: Pistacia integerrima has many medicinal uses in therapeutic as well as folk medicine. P. integerrima has been used for the treatment of different ailments such as blood purifier, anti-inflammatory, and as remedy for gastrointestinal disorders such as vomiting and diarrhea, expectorant, cough, asthma and fever. Objective: The main objective of this research work was to evaluate the effect of pistagremic acid (PA) isolated from the galls of Pistacia integerima in acute toxicity and gastrointestinal (GIT) motility tests. Methods: Compound 1 namely pistagremic acid (PA) (at 10, 50, 100 mg/kg i.p) were assessed for their in-vivo gastrointestinal motility test using charcoal screening model. Results: Results revealed that pretreatment of PA exhibited substantial safety in acute toxicity test up to the dose of 500 mg/kg p.o. However, when studied in charcoal meal GI transit test, PA caused significant (p < 0.05) attenuation of GIT motility and an increase in intestinal transit time, comparable to atropine (a muscarinic receptor blocking agent). Conclusion: In conclusion, PA displayed a strong dose-dependent reduction in GIT motility with considerable safety.
