Cytotoxic Effects of the Ethanolic Extract from Benjakul Formula and its Compounds on Human Lung Cancer Cells
Main Article Content
Abstract
Benjakul have also been used for cancer therapy by folk medicine. The ethanolic
extracts, five fractions and three pure compounds from Benjakul were investigated for
cytotoxic activities against two types of human lung cancer cell lines (COR-L23 and A549)
and one normal human lung myofibroblasts (MRC-5). The cytotoxic activities of the BEN-3
fraction which fractionated with vacuum liquid chromatography method by chloroform
solvent showed stronger cytotoxic activities against COR-L23 and A549 cells than the
ethanolic extracts and other fractions (IC50 values 28.09 and 34.43 μg/ml, respectively). Its
pure compounds, plumbagin exhibited the greatest cytotoxic activity against COR-L23,
A549 and MRC5 with IC50 values 0.36 , 0.59 and 2.17μg/ml, respectively Piperine and
gingerol exhibited cytotoxic activities against CORL23 more than A549. In conclusion, all
Benjakul extracts shown high cytotoxic activities against COR-L23 but less activities against
other cells.
