In-vitro cytotoxic activity of β-Sitosterol triacontenate isolated from Capparis decidua (Forsk.) Edgew

ObjectiveTo study the isolation and characterization of the constituent responsible for the cytotoxic activity of the ethanolic extract of stem of Capparis decidua (C. decidua).MethodsThe preliminary cytotoxic effect of isolated compound (β-Sitosterol triacontenate) was investigated by MTT assay on A549 solid tumor cells.ResultsIC50 value of the β-Sitosterol triacontenate was found to be 1 μM. The cytotoxic activity increased in a dose dependent manner in case of β-Sitosterol triacontenate.ConclusionsThe data therefore provide direct evidence for the role of β-Sitosterol triacontenate as a potent antimetastatic agent, which can markedly inhibit the metastatic and invasive capacity of malignant cells.
