Abstract:
OBJECTIVETo investigate the anti-cancer activities and the possible mechanism of Chinese herb Dioscrea bulbifera.
METHODThe herb was extracted sequentially with petroleum ether, ethanol and water. The anticancer screen were carried out in vivo with HepA in mice.
RESULTThe inhibitory effects on the formation of ascites volume and HepA cell viability in ascites were found in those extracted fractions except water fraction, the petroleum ether fraction being the strongest. Life span of mice bearing HepA ascites was prolonged after exposed to 100 mg x kg(-1) petroleum ether fraction and shortened after exposed to water fraction significantly. Besides, abnormal microstructure on HepA cells surface was found and it was supposed to be potential effect against viability of HepA which was convinced with the regeneration of HepA cells from ascites in mice exposed to petroleum ether fraction.
CONCLUSIONAnticancer active compounds are mainly extracted by petroleum ether from hydrophobic constituents of Dioscrea bulbifera and the anticancer effects were related to direct toxicity on tumor cell.
