This article describes the evaluation of molecularly imprinted polymers (MIPs) obtained by wet phase inversion for facile separation of hypericins from Hypericum perforatum L. (or Saint John�s Wort, SJW). In this respect, concentrated extracts containing hypericin and pseudohypericin were used as �phyto-templates� for creating selective cavities into the pearl shaped MIPs. The obtained MIPs were characterized by infrared and by thermal analyses. Chromatographic evaluation of the MIPs was performed relative to blank samples and it was concluded that the pearls can retain selectively the hypericins from SJW extracts.

The aim of this research has been to develop a new generation of eco-friendly binders, soluble at alkaline pH, which could allow facile recovery of explosive fillers without using organic solvents, while maintaining their chemical and physical characteristics. For this purpose, �smart� polymeric binders are to be designed based on acrylic acid and other acrylic monomers. In this view, theoretical and experimental studies have been performed in order to establish which synthesized polymer is adequate for the desired application.
