Abstract： In this paper， the extraction temperature， pH value and time were used to investigate the effects of single factor test and orthogonal test on the protein extraction effect of Nostoc commune. The results showed that the optimal protein extraction conditions were 50 ℃， 2.0 h and pH=9， and the protein recovery rate was more than 75.01%.

Keywords： Nostoc commune; protein; extraction process
