Abstract:ObjectiveTo establish the optimal extraction technology for Wendan Dripping Pills. MethodsUsing the orthogonal design, observed the effect of extractive time, extractive number and solvent amount on the extraction results, with the content of the total amino acids and aurantiamarin as the indexes. ResultsThe best extraction condition is that the crude drug is added 12 times amount water and extracted for 3 times, each time for 1.5 hours. ConclusionThis extraction technology is stable and can be used in industrial production.
