Serendipitously this "flushing" procedure has also proved to be the ideal way of cleaning our supercritical cells Supercritical C02 is used to flush out the contents of the cell, thus removing all detectable traces of soluble material and preparing the cell for the next supercritical synthetic reaction.

The equilibrium composition of the imprinted gel, assuming that there are no network defects apart for incomplete saturation of the functional sites of the templates, is obtained by solving Eqs. 7-12. Different materials and preparation conditions are modeled through the interactions parameters which is related to the excluded volume of the monomers, and Xf, which is a measure of the difference in the interactions between the different materials (monomers and templates) and is proportional to the inverse of the temperature [26]. Xf vanishes when the interactions are similar in magnitude, it is negative when the interactions are unfavorable, and it is positive when the interactions are favorable. Thus, different values of the interaction parameters effectively correspond to different preparation conditions defined by the temperature and solvent.

Help for improvements in the presentation of the material for this book was provided by the editor, Mr. D. Coleman, by Mr. B. F. Price, Director of Analytical Research at Brown Williamson, and by Ms. Carol Benton who also made numerous corrections to the material and prepared the index. The cooperation of two of the author s coworkers, Mr. J. B. Forehand and Dr. N. P. Kulshreshtha, was very useful for including most of the original data.

Plant preparations Comminuted or powdered plant material, extracts, tinctures, fatty or essential oils, resins, gums, balsams, expressed juices, and so on, prepared from plant material, and preparations whose production involves a fractionation, purification or concentration process, but excluding chemically defined isolated constituents. A plant preparation can be regarded as the active ingredient whether or not the constituents having therapeutic activities are known.
