Abstract: The protease from the fruits of siraitia grosvenorii was purified by ultra filtration(UF)and DEAE Sepharose CL- 6B chromatography.Meanwhile,the processing conditions of the purified protease,such as optimal temperature,and optimal pH were studied.The results can provide scientific basis for the further development and appfication of the protease.

Key words: Siraitia grosvenorii(Swingle)C.Jeffrey, protease, purification, characteristic
