Abstract:

To explore the edible and medicinal value of edible fungi with cinnamon as cultivation material, based on cinnamon wood cultivation material and common cultivation material, the polysaccharides of ‘Xiangwei’ mushroom and Pleurotus citrinopileatus were extracted and determined respectively. The antioxidant capacity of edible fungi polysaccharides was evaluated by ORAC method, and the hypoglycemic effect was analyzed by animal experiment. The results showed that there were great differences in polysaccharide content of edible fungi among different varieties and different cultivation materials. The polysaccharide content of ‘Xiangwei’ mushroom from common cultivation material and cinnamon cultivation material was 16.89% and 14.44% respectively, and that of Pleurotus citrinopileatus from common cultivation material and cinnamon cultivation material was 4.22% and 5.95% respectively. The antioxidant capacity of polysaccharide of Pleurotus citrinopileatus was significantly higher than that of ‘Xiangwei’ mushroom, and the antioxidant capacity of edible fungi polysaccharides from cinnamon cultivation material was significantly higher than that from common cultivation material. The polysaccharide high dose groups of ‘Xiangwei’ mushroom and Pleurotus citrinopileatus from cinnamon cultivation material could significantly relieve the diabetes symptoms in mice. The low dose groups also had a certain degree of improvement on the diabetes symptoms in mice. The efficacy of the experimental groups increased with the increase of dosage. At the same experimental concentration, the hypoglycemic effect of polysaccharide of Pleurotus citrinopileatus from cinnamon cultivation material was better than that of ‘Xiangwei’ mushroom from cinnamon cultivation material. It could be seen that ‘Xiangwei’ mushroom and Pleurotus citrinopileatus from cinnamon cultivation material had considerably high polysaccharide content, and both had strong antioxidant and hypoglycemic effects. The results of this experiment can provide theoretical reference for the development and utilization of cinnamon resources in the production of rare edible fungi such as ‘Xiangwei’ mushroom and Pleurotus citrinopileatus.
