Abstract:

The present study aimed to optimize supercritical carbon dioxide extraction of lignans from flaxseed using
response surface methodology based on a 3- variable, 3- level Box-Benhnken design. The results showed that the optimum
conditions were extraction pressure of 25.69 MPa, extraction temperature of 41.54 ℃, extraction time of 182.80 min. Under
these conditions, the model predicted and experimental values of lignans yield were 2.401% and 2.398%, respectively.

Key words: response surface methodology, flax seed, lignans, supercritical CO2 extraction
