Patent Title: Molercularly imprinted polymeric pearls for selective extraction of hypericin from phytoextracts
Publication date: 2014
Publication number: RO129825

Abstract: The invention relates to molecularly imprinted polymeric pearls meant for the selective extraction of hypericin from phytoextracts. According to the invention, the pearls are made of acrylonitrile-co-acrylic or methacrylic acid copolymers with 75...90% acrylonitrile and, for the remainder, acrylic or methacrylic acid, having a relative polymer viscosity of 1.45...1.95, a diameter of 0.8...1.2 mm, a specific surface of 70...120 m/g and an imprinting factor of 2...4.5.
