  • A compound has been isolated from the methanol extract of Styrax japonica bark using conventional chromatographic methods including silica gel chromatography, TLC and HPLC. The molecular formula of Styraxlignolide F analyzed by spectrometric analyses using FAB-MS, NMR was found to be $C_{27}H_{34}O_{11}Na$. The cytotoxicity of the styralignolide F was showed 15.2% in $1.0mg/m{\ell}$ on human kidney cell (HEK 293). As anticancer activity of $CH_2Cl_2$ fraction, over 60% of AGS and MCF-7 cells were inhibited in concentration of $1.0mg/m{\ell}$. In the results of anticancer test using quantification of Bcl-2, $CH_2Cl_2$ fraction showed lower Bcl-2 and p53 expression than those of styraxlignolide F and other fractions. In apoptosis of human lung carcunoma cancer cell (A549), $CH_2Cl_2$ fraction showed the highest inhibition rate (46.9%) and styralignolide F was the next (43.5%). The $CH_2Cl_2$ fraction showed higher anti-cancer activities than isolated substance (styraxlignolide F), probably due to the crude extract showing synergic effects by other components.
