【Abstract】 A process for isolating L-hydroxyproline and L-proline has been presented. The procedures of this method were as follows: first hydrolyzed the glutin by HCl,then oxidized it by sodium nitrite,and finally isolated L-hydroxy proline and L-proline from hydrolysis solution by positive ion exchange resin-D61. The average yields of obtained pure L-hydroxyproline and L-proline were calculated in the end.更多还原
