| 摘要 |
According to the present invention, the biological or pharmacological activity of a test material like a plant or herbal material, an extract of a plant or herbal material, a natural or synthetic compound or some combination thereof, can be quantified by observing the pattern of structural changes induced in a eukaryotic cell's proteins. These structural changes may be evidenced by protein phosphorylation, by protein-protein interactions and the like. The amount and nature of protein phosphorylation is qualitatively and quantitatively related to the in vitro concentration of biologically/pharmacologically active components to which the mammalian cells are exposed. Additionally, formation or loss of protein-protein complexes may be determined in whole cell homogenates through the use of non-denaturing electrophoresis and staining for proteins or protein phosphorylation. The present invention allows natural products to be formulated into nutritional supplements and pharmacological preparations of consistent biological/pharmacological activity without the need to identify any of the chemical constituents responsible for the biological or pharmacological response.
