Objective: To optimize SFE-CO2 technique for Fufang Kuiyang Gao. Method: Using the paste rate
the contents of total anthraquinones
imperatorin and ferulic acid as composite index
the effect of condition including temperature
pressure
extraction time on SFE-CO2 extraction was invesitaged by orthogonal design. Result: The influencing sequence of factors on SFE-CO2 for composite index was temperature>pressure>extraction time
and temperature was the most remarkable factor. The optimized extraction condition was as follows: temperature at 55 ℃
pressure at 30 MPa and extration time 1 h. Conclusion: The optimized extraction technology was stable
