Abstract:
Objective To optimize the extraction technology of Morchella polysaccharide.Methods With GIM5.69(Morchella esculenta(L.) Pers.) and GIM5.29(Morchella elata) as the research object,the difference of polysaccharide yield with lixiviation in polysaccharide extraction between ultrasound and enzyme was observed.At the same time,the difference of polysaccharides yield of these two Morchella was compared.Result Ultrasound and enzyme both can improve the polysaccharides yield,and the effect of 10 min of ultrasound was the best.The polysaccharides yield of GIM5.69 was higher than that of GIM5.29,which means different strain has different polysaccharides yield.Conclusion The best extraction condition is 10 min of ultrasound at the frequency of 40 kHz,heating 150 min at 90 ℃ and lixiviation twice.
