ZHANG Xiao-juan et al(School of Biological Science and Engineering,Shaanxi University of Technology,Hanzhong,Shaanxi 723001)  
[Objective]The study aimed to improve the extracting rate of water-soluble pachyman and find the optimal conditions of extraction. [Method]The main influencing factors of microwave-assisted enzyme extraction method were optimized by uniform design.[Result]The optimal conditions were obtained as follows:microwave extraction time 17 min,power 550 W,ratio of solid to liquid 1:30,extraction times 2, enzymolysis temperature 60℃,enzymolysis time 120 min,enzyme quantity 0.5%,pH value 6.Under the above conditions,the extracting rate of pachyman was 3.58%.[Conclusion]Microwave-assisted enzyme extraction is the effective method for extraction of Pachyman.
