Objective: To optimize the optional extraction method of Radix Linderae from Dangwu Dispersible Tablet. Method: Extracting method
extraction solvent and extraction times were selected to determine the factors and levels by single-factor test method with the content of linderane as index. Then content of linderane was used as index to evaluate the technologies based on orthogonal design
considering ointment rate at the same time
in which 4 factors considered were the concentration of ethanol
solvent consumption
extraction temperature and extracting time. Result: The optimum extraction processes was ultrasonic extraction technique
50 ℃
adding 6 times amount of 90% ethanol
extracting for two times with 20 min each time. Conclusion: The method has the advantage of speediness
higher extraction rate etc. This process is stable and reliable.
