Reaction Steps

The solution thus obtained is filtered and then concentrated, in a reactor under reduced pressure, until an aqueous phase is obtained, according to the same principle as the preceding concentration. It is then readjusted by adding ethanol in order to obtain a stabilized aqueous-alcoholic solution having a solids content of 200 g +/−20 per liter and an alcohol percentage of 35%+/−3.5% volume/volume. A prepurified phase rich in madecassoside and in terminoloside and still containing asiaticoside is thus obtained.
