[0002] Scyllo-inositol is a diastereomer of myo-inositol, which exists in plants, animals and some bacteria. It has certain effects on the treatment of brain diseases such as Alzheimer's disease, Down syndrome and Angelman syndrome. In addition, scyllo-inositol can lower uric acid levels and is used to treat hyperuricemia.

[0003] At present, the preparation method of scyllo-inositol is mostly to add boric acid and crude enzyme solution to myo-inositol for conversion, and myo-inositol is converted into scyllo-inositol and then into scyllo-inositol. Boric acid is added in advance to react with the generated scyllo-inositol to obtain a boric acid scyllo-inositol complex salt precipitation, thereby achieving the purpose of scyllo-inositol separation. Phosphoric acid is then used to decompose the complex salt, and ethanol is then added to obtain scyllo-inositol. This method will produce a large amount of mother liquor while obtaining scyllo-inositol. The mother liquor contains ethanol, phosphoric acid, boric acid, water and a small amount of metal ions.
