Abstract
The hydrolyzate of Delonix Regia seed extract is fractionated sequentially on Dowex 50 X 8 resin and on QAE Sephadex A 25. Purification is completed by recrystallisation from ethyl alcohol. 3-hydroxyproline is destroyed by NO2H and by chloramine T, which prevents from using most of the colorimetric reactions in use for 4-hydroxyproline. For its characterization, 3-hydroxyproline may be clearly separated from 4-hydroxyproline by TLC chromatography and by high voltage paper electrophoresis.
