Abstract: In this paper, saponin was purified by flocculation-precipitation, and crude extraction from camellia oleifera seed shell was as raw material. On the basis of single factor experiments, purification process was optimized using response surface methodology, and a mathematical regression model was established by Mintab15.0 software. Optimal purification conditions obtained from this model were as follows: 16% Chitosan solution added in crude extraction; 1.78% Ca O was added in supernatant after flocculation to subside for 3.01 h at 32.75℃; 4.09% NH4HCO3 was added to the sediment, and then released at 52.2℃ for3.17 h. Under conditions, content of camellia saponin was 60.4% in the final.
