摘要
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<sub>50</sub> value of theβ-Sitosterol triacontenate was found to be 1μM.The cytotoxic activity increased in a dose dependent manner in case ofβ-Sitosterol triacontenate.Conclusions:The data therefore provide direct evidence for the role ofβ-Sitosterol triacontenate as a potent antimetastatic agent,which can markedly inhibit the metastatic and invasive capacity of malignant cells.
