Study on the Isolation of Lentinan within Definite Molecular Weights / 中国药房

ABSTRACT

OBJECTIVE:To study the isolation of lentinan,the average molecular weight of which ranged within400000to600000.METHODS:The fine lentinan was purified by2—diethyllaminoethyl—cellulose anion exchange column chro-matography,which was then isolated by dextran gel G-200column chromatography with the molecular weights determined by high performance gel chromatography.RESULTS:The average molecule weight of the isolated lentinan ranged from400000to600000.CONCLUSION:This method can be used for the isolation of lentinan.
