Abstract
[ Objective] To explore the optimal conditions for extracting pvlysaceharide from Auricidaria auricular.and to study its physiochem-ical properties and antibacterial activities. [ Method] The extraction conditions for A. auricular polysaccharidea were optimized by orthogonal test,and its physiochemical characteristics and antagonistic activities on bacteria and molds were tested. [Result] The optimized condition is with sample to liquid ratio of 1:50, temperature of 90 ℃, and extraction time of 2. 5 h. Under (he optimized condition, the yield of polysaecha-ride was 7. 3% ,with polysaccharide content of 77.81%, Containing aldose and amylase.the polysaccharides of A. auricular is soluble in water. The inhibitory effect on bacteria is significantly stronger than on molds that the minimum diameter of inhibition zone for bacteria is 12.7 mm, while 7.9 mm for the molds. [ Conclusion] This study provided scientific basis for the development and utilization of A. auricular polysac-charides.关键词
