Abstract:ObjectiveTo study the best extraction process of Tangkuei Blood-supplementing decoction. MethodsUsing the orthogonal design which contained 3 factors (amount of water, extracted times, extracted hour) and 3 levels to determine the content of ferulic acid as the index of evaluation. ResultsThe optimum conditions for the extraction of ferulic acid were 12 times of water, extracted twice and each time lasted 2 hours. ConclusionThe extraction process for ferulic acid from Tangkuei Blood-supplementing decoction was stable and usable.
