Objective: To investigate the optimum extraction technology of bergenin from Yinxian Tongfeibao granules. Method: The optimum extraction process was investigated by L9(34)orthogonal design with the content of bergenin as index.The chief factors were ethanol concentration
the amount of ethanol
flow rate of percolation fluid which influencing extraction efficiency. Result: The optimum extraction technology was as follows:percolated with 60% ethanol
collected 10 times(to raw material)percolation fluid
flow rate of percolation was 5 mL·min-1·kg-1. Conclusion: The optimum extraction technology is scientific
