  • preparative separation of dryofragin and aspidin bb from dryopteris fragrans extracts by macroporous resin Column Chromatography
    Journal of Pharmaceutical and Biomedical Analysis, 2012
    Co-Authors: Xiaojuan Li, Yujie Fu, Wei Wang, Lin Zhang, Chunjian Zhao, Yuangang Zu
    Abstract:

    Abstract A simple, efficient and environment-friendly chromatographic separation method was developed for preparative separation and enrichment of dryofragin and aspidin BB from Dryopteris fragrans. The adsorption properties of twelve macroporous adsorption resins were evaluated. The three selected resins were further screened depending on the separation performance of their packed Columns, in which AB-8 resin showed better separation efficiency for dryofragin and aspidin BB. In order to maximize Column efficiency, the operating parameters (flow rate, ethanol concentration and volume) of the resin Column Chromatography were optimized and compared with the conventional resin Column adsorption. After preparative separation and enrichment on resin Column Chromatography, the contents of dryofragin and aspidin BB in the product were 8.39- and 5.99-fold increased with recovery yields of 91.22% and 75.64%, respectively. Moreover, the regenerated adsorbent exhibited excellent reusability within at least five cycles of adsorption/desorption. It suggested that multi-targets would be enriched effectively by resin Column Chromatography.
