Abstract:
AIM: To screen macroreticular resins for isolation and purification of flavonoids from the leaves of Diospyros kaki Linn (FLDK). METHODS: 8 kinds of macroreticular resins were assayed for their adsorbability and deadsorbability as well as the adsorption kinetics to FLDK. RESULTS: Polyamide and AB-8 resin were found with good adsorbability and deadsorbability as well as adsorption kinetics to FLDK. CONCLUSION: AB-8 resin and polyamide could be used for preparing high contents of FLDK. FLDK-P70, a flavonoid extract contained more than 77% of flavonoids was prepared from the extract of leaves of Diospyros kaki by polyamide adsorption column isolation.
