摘要
Objective To optimize the extract technology of active lignins from the fruits of Schisandra chinensis. Methods The content of schizandrin, gomisin A, and deoxyschizandrin were selected as standards to evaluate the efficiency of smashing tissue extraction (STE). Solid-liquid ratio, extracting times, ethanol concentration, and extracting time were investigated through orthogonal test. Results The optimized conditions for STE were ten times amount of 80% EtOH, extracting for three times, and 2 min for each time. Conclusion STE could obtain relatively higher yield, simplicity of operation, and benefit for environment protection. It could be better choice for the extraction of S. chinensis.
