The method and materials of this invention make possible substantially faster techniques for organic-aqueous extractions and routine chemical reactions work-ups. The inventive material uses silicone elastomer-coated glass powders, magnetic powders, and sponges as absorbents to extract organic products from an aqueous mixture. After separation from the mixture, these different forms now loaded with organic products can serve as a convenient input for flash chromatographic separations or other processing. With these techniques, tedious liquid-liquid extractions are replaced by a simple solid filtration or transfer and emulsion formation is eliminated. These versatile sorbents can also be used for larger scale work-ups, various extractions of organics from an aqueous solution (e.g., water purification) or gas phase and various analytical or other applications.

Disclosed herein is a method for obtaining compounds and compositions from plant and fungus materials by thermal treatment, affinity capture, filtration, and release through multi-phasic transitions between gas, solid, and liquid states. The compounds of interest are obtained by manipulating the temperature and pressure of the heating chamber. The compounds in gas phase are passed through an affinity medium which captures the compounds of interest in either solid or liquid phase by exposing the compound of interest to the localized micro-affinity environment of the medium. The compounds are separated from the medium using direct competition with solvent or buffers optimized for the specific chemical properties of compounds.

In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W).sub.a(Q).sub.b(T).sub.c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.
