A method of preparing ganglioside

摘要

A method of preparing Ganglioside GM3 which comprises converting Ganglioside GD3 into Ganglioside GM3 in an alkaline condition is disclosed. The conversion of Ganglioside GD3 into Ganglioside GM3 is preferably carried out by thermal treating Ganglioside GD3 in an alkaline condition. The thermal treatment is preferably carried out at a pH ranging from 8 to 11 and at a temperature ranging from 30 DEG C to 140 DEG C.
