Objective: To optimize extraction process of total flavonoids from Viscum ovalifolium
and to preliminary evaluate in vitro inhibitory effect of total flavonoids on human hepatoma cell Hep3B. Method: With rutin as standard substance
the content of total flavonoids was determined by UV
orthogonal test was used to optimize extraction technology of total flavonoid from V. ovalifolium with extraction time
extraction temperature
solid-liquid ratio and the concentration of ethanol as factors
extraction times was investigated by single factor test;In vitro inhibition effect of total flavonoids on Hep3B was measured by MTT method. Result: Optimum extraction technology was:extracted 2 times with 30 times the amount of 60% ethanol at 80 ℃
2 h per time;In vitro anti-tumor activity screening showed
when treated with the concentration of total flavonoid 500 mg·L-1
rate of growth inhibition on Hep3B was 51.40%. Conclusion: Optimized extraction conditions was stable and feasible
total flavonoids from V. ovalifolium showed some in vitro inhibitory effect on Hep3B.
