A CRUDE EXOPOLYSACCHARIDES PRODUCED FROM LEATIPORUS SULPHUREUS VAR. MINIATUS HAVING HYPOGLYCEMIC ACTIVITY AND PREPARATION METHOD OF THE SAME

摘要

An extracellular polysaccharide which is derived from media of Leatiporus sulphureus var. miniatus is provided to have recovering effects of insulin secretion cells which is damaged by streptozotocin and treat insulin secretion failure. An extracellular polysaccharide which is derived from media of Leatiporus sulphureus var. miniatus has anti-diabetes activity and comprises carbonhydrate and protein. A method for producing the extracellular polysaccharide comprises: a step of adding deep sea water in culture media and preparing liquid culture media; a step of centrifuging of liquid media; a step of adding alcohol in supernatant; a step of centrifuging; and a step of freeze-drying the precipitate.
