Parasiticidal and brine shrimp cytotoxicity potential of crude methanolic extract of rind of Punica granatum Linn against round worms and tape worms

ABSTRACT

Rind of Punica granatum is traditionally used for anthelmintic purposes. The current work describes the possible anthelmintic activity of crude methanolic extract of Punica granatum [Pg. Cr] against round worms [Ascaridia galli] and the tape worms [Raillietina spiralis]. Brine shrimp cytotoxicity is also performed. Brine shrimp cytotoxic activity was tested using different concentrations [1000µg/ml, 100µg/ml and 10µg/ml] of Pg.Cr. In vitro anthelmintic activity of Pg. Cr was determined against the parasites using albendazole and piperazine citrate as st and ard anthelmintic drugs in concentration 10 mg/ml. LC50 value for Brine shrimp cytotoxicity was 189.44+/-28µg/ml. In test concentration of 40mg/ml of the Pg. Cr, Raillietina spiralis was paralyzed in 23 minutes. However, for parasiticidal activity [death of the parasite], it took less time [40 minutes] as compared to st and ard Albendazole. Time taken for death of the parasite Raillietina spiralis, in concentration 40 mg /ml, is 40 min. While st and ard drugs took more time to kill the Raillietina spiralis. Pg. Cr took 19 minutes to paralyze the Ascaridia galli at concentration 40 mg/ml whereas; it took 48 minutes for to kill the parasite Ascaridia galli. The current work confirms the traditional use of rind of Punica granatum as anthelmintic against Raillietina spiralis and Ascaridia galli. Results of brine shrimp cytotoxicity assay warrant for the isolation of cytotoxic compounds. List of abbreviation Pg. Cr = Crude methanolic extract of Punica granatum
