Research on antibacterial activity of Schisandra chinensis extracts by microwave-assisted.This paper investigated

the optimum microwave-assisted extraction process of Schisandra chinensis by application of orthogonal tests. 

Taking the antibacterial activity as index, with extraction time, extraction power, solvent and solid-liquid 

ratio as factor's, extraction technology was optimized by L9 (34) orthogonal test. By using the mycelium growth

rates method, the inhibition of Schisandra chinensis extracts were measured, the lethal concentration EC50 

were calculated. 


It was found that the optimum extraction technology were: microwave power at 400W, extraction time at 5 min, 

solid-liquid ratio is 5:70 and solvent is acetone.
