| titleOfInvention | Steviolbioside metal copper complex and preparation method thereof |
| abstract | The invention provides a steviolbioside metal copper complex and a preparation method thereof, wherein the structure of the steviolbioside metal copper complex is shown as a formula (I), and the complexing rate of metal copper is more than 77%. The preparation method of the steviolbioside metal copper complex comprises the steps of dissolving steviolbioside in lower alcohol, dissolving copper salt in organic acid aqueous solution, mixing the two solutions, adjusting the pH value to be alkalescent, adding an auxiliary complexing agent, heating and stirring, cooling and crystallizing the reaction solution, filtering, washing and drying to obtain the steviolbioside copper complex. In the complexes formed by a plurality of steviolbiosides and metals, the complex formed by the steviolbiosides and the metal copper has obvious antioxidant effect, and the complex formed by other metals and the steviolbiosides has no obvious antioxidant effect, so that the advantages of the steviolbioside metal copper complex provided by the invention are highlighted. |
