Abstract: The rapid extracting technology for schisandrol A from Schisandra chinensis was investigated by using orthogonal experimental design, and the content of schisandrol A was detected by HPLC. The optimum extracting technology was obtained as follows: 80% ethanol as for the extract liquid, 10 kv/cm electric field intensity, impulsion frequency of 10, and 1:10 as the ratio for material and liquid. The effect levels of these factors successively were electric field intensity, the ratio for material and liquid, and impulsion frequency. The content of schisandrol A was 0.76% in S. chinensis, and the yield of extract was 27.886%. The extracting technology is feasible, economic with high recovery ratio and saving time in the process.
