Synthesis of gelatin-PVA adsorbent and its application in the separation of ginkgo flavonol glycosides and terpene lactones

摘要

Spherical adsorbents derived from the glutaraldehyde cross-linked hybrid of gelatin and polyvinyl alcohol (PVA) were synthesized, and their adsorption selectivity for ginkgo flavonol glycosides and terpene lactones was also investigated in deetail. An adsorbent with an appropriate gelatin content can selectively adsorb favonol glycosides with a high adsorption capacity based mainly on hydrogen bond interactions, while showing only a fairly low adsorption capacity for terpene lactones.
