Dynamic microwave-assisted extraction (DMAE) technique was used for the fast extraction
from Saussurea medusa Maxim. In order to achieve the optimal extraction conditions,
variables involved in the extraction procedure such as extraction methods, extraction solvents,
methanol concentration, ratio of solvent to raw material, extraction time, microwave
power and extraction cycles were investigated. Orthogonal L9 (3)4 test design in the
extraction mode was used for optimization extraction conditions and the maximum content of
arctignenin was 10.891 ± 0.003 mg g-1 obtained by once DMAE at 390 W with 50 mL
methanol for 20 min. The extraction efficiency of arctigenin with DMAE was higher than
other traditional extraction methods.
