Research in auxiliary mention and antioxidant in vitro of ganoderma lucidum polysaccharides

In this paper,single factor and orthogonal experiments were designed to optimize the microwave extraction conditions of ganoderma lucidum polysaccharides from the aspects of temperature,material-water ratio,microwave power,microwave extraction time in this paper.Results showed that after pre-soaking in distilled water for an hour,when the temperature,material-water ratio,microwave power and microwave extraction time was respectively60 ℃,1∶40,100 W,30 min,the obtaining rate of polysaccharides was the highest.It proved that ganoderma crude polysaccharides had some reducing ability and scavenging capacity of different radicals,which meant it had a certain selectivity of scavenging free radical.It might be related to impurities in the crude polysaccharides,polysaccharide structure and scavenging mechanisms.
