Separation of 10-Hydroxy-2-Decenoic Acid from Royal Jelly by Use of Macroporous Resin

doi:10.7506/spkx1002-6630-201306025

Abstract

Abstract: 10-Hydroxy-2-decenoic acid (HDA), a special bioactive component in royal jelly, has many physiological functions. In this study, we investigated the adsorption and desorption properties of HDA from royal jelly on macroporous resin and explored the optimal elution solution. X-5 resin had the best adsorption and desorption capacity for HDA and its saturated absorption capacity was 9.7 mg/g. The optimal elution solution was 90% alcohol, resulting in a dynamic desorption rate of 91.7%. The final product prepared by vacuum freeze-drying was white power with a purity of 80.4% as analyzed by HPLC.

Key words: royal jelly, 10-hydroxy-2-decenoic acid, macroporous resin, isolation and extraction
