Product Description

ADS-17 Macroporous adsorption resin (Hydrogen key)

1.Application :

ADS-17 resin is medium-polar type adsorbent. It can form hydrogen bond with flavonoid molecule tha can enhance the selectivity of adsorbent resin and gains GBE with high flavonoid content,ADS-17 is stable under high temperature,solvent and acidic or alkaline condition.the longest use life is 7 years.Extraction of ginkgo flavone glycoside and ginkgolide with high selectivity, their contents can reach 40% and 10% respectively.
