ABSTRACT:
Glucopeptide in the form of a white powder, which is effective for prevention or treatment of nephritis, is produced by: preparing a concentrated extract from watermelon pulp juice; adding a lower alcohol to this extract to obtain an alcoholic solution with an alcohol concentration of approximately 80 to 95% by weight; adding acetone to the resulting solution in a volume of 1.5 to 2.5 times the volume of the solution to obtain a precipitate of glucopeptide; repeating at least once the purification procedure for the precipitate which comprises dissolution with a similar alcohol and precipitation from the resulting solution with acetone; and finally removing the remaining solvent to dryness.
