Abstract:
AIM:To study the extraction of Schisandra Chinensis (Turcz) using supercritical carbon dioxide as extracting ageat. METHODS: The study was carried out through orthogonal test design,the content of schizandrin from Schisandra Chinensis (Turcz) was selected by 3 influencing factors, extract temperature, extract pressure and separation temperature. RESULTS:The optimal condition for the extraction as A3B2C1 Schisandra Chinensis (Turcz) was extracted by supercritical carbon dioxide, extract pressure was 25MPa, extract temperature was 50?C, separation was 7 MPa, separate temperature was 60?C, extract time was 2.5h and runing amount of CO2 was 15kg?h -1. CONCLUSION:It is feasible that supercritical carbon dioxide is used in the preparation of Schisandra Chinensis (Turcz).
