In vitro anthelmintic activity of Physalis minima ethanolic leaves and stem extracts against Paramphistomum cervi from cattle

Abstract

BackgroundCrude ethanolic extracts of leaves and stem of Physalis minima (Solanaceae) were evaluated for in vitro anthelmintic activity on the Bangladeshi mature parasitic flatworm Paramphistomum cervi (Trematoda) in cattle. To compare the test results, Albendazole was used as a standard drug.MethodsA leaves and stem extract of the P. minima was prepared in a Soxhlet apparatus using ethanol as a solvent. After concentrating in a vacuum rotary evaporator, the extract was analyzed for phytochemical activities. In vitro anthelmintic activity was tested against the flat worm P. cervi.ResultsThe results of anthelmintic activity of P. minima were evaluated by paralysis instead of taking as of the paralysis time and death time of the flatworm. The study concluded that the ethanolic leaves and stem extracts of P. minima had anthelmintic activity in a dose-dependent inhibition of spontaneous motility of flatworm. From the screening experiment, the crude extracts showed the best anthelmintic activity. Furthermore, our phytochemical studies point out that ethanolic extract of the leaves and stem of P. minima contains flavonoids, phenols alkaloids, terpenoids, tannins, steroids, proteins and cardiac glycosides.ConclusionsThe studies of total phenolic and flavonoids content were quantified for all parts of the plant. The results of the present study suggest that P. minima extracts are a promising alternative to the commercially available anthelmintics for the treatment of gastrointestinal nematodes of cattle. Further research is required to confirm the possibility of the antimicrobial and antiproliferative applications.
