Objective: To develop a simple method for effectively extracting protein from schisandra with the comparison of three extractive methods. Method: The extracts of the three methods were determined with SDS-PAGE

the content of protein was determined with the Lowry method

and a HPLC method was established for the determination of the amino acids in schisandra extract. Result: The protein content of the three methods was 58.44%

19.21% and 26.18%.The amino acids content of the three methods was 57.46%

15.41% and 23.14%. Conclusion: Purified protein and its amino acids were obtained by defatted ammonium sulfate precipitation procedure

and the content of protein was acceptable.This method is easily and more feasible.
