Numbers of compounds and their mixtures, which are produced by plants, can be obtained by extracting plant materials by supercritical fluids. Phytosterols and phytoecdysterotds represent an important family of these plant products. They can be used in a synthesis of supramolecular structures with possible importance for targeted effect of drugs or other biological(y active compounds. Target organisms for the compounds investigated are: (a) insects - pests and human food competitors, also important as model system in investigation of convenient application forms of biologically active compounds; (b) cell cultures used during basic pharmacological research. Supramolecular structures may form convenient matrices for practical application of the biologically active compounds. It has already been proved that numbers of medicinal or cultural plants produce important natural compounds. The present question has appeared to be answered, if so far inutile weeds may be turned into important sources of pro-drugs for disease treatments.
