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

OBJECTIVE@#To study the isolation and characterization of the constituent responsible for the cytotoxic activity of the ethanolic extract of stem of Capparis decidua (C. decidua).@*METHODS@#The preliminary cytotoxic effect of isolated compound (β-Sitosterol triacontenate) was investigated by MTT assay on A549 solid tumor cells.@*RESULTS@#IC(50) 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.@*CONCLUSIONS@#The 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.
