Background: Murraya paniculata is traditionally used for management of gut, air way and cardiovascular disorders. The study was conducted for provision of pharmacological rationalization for folkloric uses of Murraya paniculata in gut, air way and cardiovascular problems. Methods: Aqueous-ethanolic extract of Mp. Cr was tested using in vitro techniques on isolated tissue of rabbit (jejunum, trachea and aorta) to detect the possible presence of spasmolytic activity. The responses of tissues were recorded using isotonic transducers coupled with PowerLab data acquisition system. Results: Application of the extract of Mp. Cr relaxed spontaneous and high K+ (80mM)-induced contraction in rabbit jejunum preparation. Because it shifted the CRCs (Calcium response curve) towards the right side so the possible blockade was of calcium channel similar to verapamil. In rabbit trachea, extract of Mp. Cr produced relaxation of carbachol and high K+ induced contractions. When plant extract was checked further on isolated aorta for its possible vasodilator effect, it caused relaxation of phenylephrine and high K+-induced spastic contractions at different doses. Conclusion: These results indicate that Murraya paniculata shows anti-spasmodic, bronchodilator and vasodilator activity facilitated through Ca++ antagonist mechanisms.
