Abstract: We compared the contents of Salvianolicacid B, protein and soluble sugar, light transmittance and DPPH free radical scavenging rate of Salvia miltiorrhiza Bge.between vacuum extraction and conventional extraction. Optimum conditions of vacuum extraction were ethanol concentration of 50%, solid to liquid ratio of 1:10, vacuum degree of 0.07 MPa, temperature of 50 ℃ and extraction time of 1.0 hour. For identical extraction agents, extraction rates of Salvianolic acid B and DPPH free radical scavenging rate were equal for vacuum extraction and heat reflux extraction, greater than those of ultrasonic extraction and warm immersion extraction.The extract yield, contents of protein and soluble sugar of vacuum extraction were higher than those of ultrasonic extraction and warm immersion extraction, but lower than those of heat reflux extraction. Vacuum extraction of Salvia miltiorrhiza Bge.has high extraction rate of Salvianolic acid B, clear extracting solution and less impurity, superior to conventional extraction.

Key words: DPPH, vacuum extraction, Salvia miltiorrhiza Bge., Salvianolic acid B
