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

摘要

Objective:To study the isolation and characterization of the constituent responsible for the cytotoxic activity of the ethanolic extract of stem ofCapparis decidua (C. decidua).Methods:The preliminary cytotoxic effect of isolated compound (β-Sitosterol triacontenate) was investigated byMTT assay onA549 solid tumor cells.Results:IC50 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.
