Protective effect of a polysaccharide isolated from a cultivated Cordyceps mycelia on hydrogen peroxide‐induced oxidative damage in PC12 cells

Cordyceps sinensis as a well-known traditional Chinese tonic has many therapeutic functions. In the present study, an acid polysaccharide (APS) was isolated from cultivated Cordyceps mycelia by ion-exchange and sizing chromatography. The protective capacity of APS against H(2)O(2)-induced oxidative damage in rat pheochromocytoma PC12 cells was investigated by measuring cell viability, lactate dehydrogenase (LDH) release, antioxidant enzyme...
