In vitro potential effect of Pipper longum methanolic extract against protoscolices of hydatid cysts

This study aimed to evaluate the efficacy of methanolic extract of P. longum (PLM) against protoscolices of hydatid cyst in vitro. Four different concentrations of PLM extract (25, 50, 100 and 150 mg/ml) were used for the experiments. The metabolites in the PLM extract were characterized by Gas chromatography-mass spectrometry (GC-MS). The results showed the highest lethality of PLM extract in 50 mg/ml for 60 min exposure. The IC₅₀ value obtained about 20 mg/ml for 60 min of PLM extract exposure. In this study, valuable findings were obtained for the first time about the scolicidal activity of P. longum, which is expected to conduct further studies in this field in the future.
