Abstract:
Objective:To optimize the ethanol reflux extraction process for Aitong cataplasm .Methods: Orthogonal design was used to investigate the effect of solid-liquid ratio,extraction time and times on the extraction technology of Aitong cataplasm with the content of asarinin and dry extract yield as the indices .Results:The best extraction conditions were as follows:extracted 3 times with 8-fold amount of 70%ethanol, and 1 hour for each time.Conclusion: The optimized extraction process is stable and feasible , which can be used to extract Aitong cataplasm .
