Abstract:
Objective: To study the purification process of galangin in Alpinia officinarum Hance with macroporous adsorptive resin. Methods: The static adsorption ratio and elution ratio were used to evaluate the adsorption performance of the tested resins for the separation and purification of galangin. Results: Resin HPD-600 showed good separation performance and was selected to purify galangin in Alpinia officinarum Hance. With this resin, the static adsorption ratio of galangin was 91.8% and the desorption ratio of galangin was 85.36%. Conclusion: The purity of the product was up to 92.4%, while it was just 59.4% before purification. This adoption of macroporous adsorption resin to adsorb and purify galangin in Alpinia officinarum Hance was feasible.
