Abstract: Response surface methodology was used to optimize the microwave-assisted aqueous enzymatic extraction of cyclic adenosine 3’,5’-monophosphate (cAMP) from Chinese jujube (Zizyphus jujuba Mill.) grown in Xinjiang. The anti-fatigue effect of the cAMP extracted was investigated. The optimal extraction conditions was found as follows: enzyme concentration 1.5% (a mixture of cellulase, hemicellulase and pectinase, 1:1:1 (m/m)), temperature 31.3 ℃, time 20 min and microwave power 500 W. Under these conditions, the yield of cAMP was 560.9 μg/g. The results showed that the cAMP could extend exhaustive swimming time and enhance swimming endurance in mice, suggesting good anti-fatigue effect. Therefore, cAMP holds great promise for its application in the food and pharmaceutical industry.

Key words: Zizyphus jujuba, cyclic adenodsine 3’,5’-monophosphat (cAMP), microwave-assisted aqueous enzymatic extraction, swimming time
