Abstract

The present investigation was planned with an objective to screen phytochemically andneuropharmacologically the ischolar_mains of Carissa carandus Linn.in rats. Carissa carandus Linn.(karaunda), common herb of dogbane family Apocynaceae. It has been used as additive in Indian pickles1. The extraction of Carissa carandus Linn. ischolar_mains was carried out by Soxhlet apparatus by successive solvent extraction in the order of increasing polarity with solvents such as hexane, methanol and water respectively for 24 hours. Phytochemical screening of the extracts reveals the presence of following chemical constituents such as carbohydrates, proteins, lignans, flavonoids, terpenes, saponins glycosides, cardiac glycosides etc. Nootropic activity was carried out with methanolic extract (200 mg/kg) in albino rats by using object recognition test. The rats of all the groups are placed one by one in an empty object recognition test chamber to get habituated to the environment for a period of 5 minutes before the test session. The rats were allowed to explore a familiar object (F) and a new object (F1) on first day test trail for a period of 5 minutes. Second day test trial includes exploration of a previous familiar (F) object and a new object (N). The result obtained indicate that discrimination index with control rats were found to be 0.0470±0.113 sec, whereas with test treated rats discrimination index was found to be 0.2042 ±0.412 sec. This increase in discrimination index with Carissa carandus Linn. methanolic ischolar_main extract treated rats in object recognition test suggests that Carissa carandus Linn. ischolar_mains posseses significant memory enhancing potential.

Abstract

The present research was designed to evaluate the analgesic potential of Boerhavia diffusa ischolar_main powder 150 mg/kg, p.o in albino mice. Boerhavia diffusa is a popular herb in ayurveda which is also known as Punarnava. Boerhavia diffusa ischolar_main powder was procured from a local ayurvedic store. The analgesic effect of the ischolar_main powder was evaluated by using acetic acid induced writhings test in mice. It was found that Boerhavia diffusa ischolar_main powder at a dose of 150 mg/kg treated for 15 days has significantly inhibited pain induced by acetic acid by decreasing the number of writhing responses such as extension of hind limbs (22±0.77), abdominal constrictions (13±0.08) and trunk twisting (20±0.55) when compared to control treated mice i.e extension of hind limbs (38±0.17), abdominal constrictions (26±1.23) and trunk twisting (24±0.55) in control mice. The results were compared with standard diclofenac sodium (25 mg/kg, p.o) treated mice. Hence it is evident from the above results that boerhavia diffusa at 150 mg/kg possesses significant analgesic potential.
