Establishment of dynamic model for flaxseed lignans extraction with solvent method

摘要

The flaxseed lignans were extracted with 70% ethanol solution at ambient temperature. Based on the first Fick' law, the extraction model was established; according to the experimental data obtained at different conditions, the model was solved by means of "minimum two multiplication" method and the pending constants were determined; the model was validated with experimental data and the results proved that the forecasting precision of this model was error less than 7%.
