  • Hydrolysis and purification of active plant compounds suitable for topical application
    Patent number: 7718813
    Abstract: A composition suitable is disclosed for topical application for preventing and treating changes associated with skin aging and formation of abnormal skin lesions. The composition is derived by hydrolyzing a source composition in an acidic solution. The source composition can be, e.g., a soy composition and can include one or more isoflavones, phytoestrogens, sitosterols and saponins. After hydrolysis, water is added to the acidic solution to produce a first precipitate, which is then dissolved in an alcohol solution. The alcohol solution is then separated from undissolved portions of the first precipitate, and the alcohol in the separated alcohol solution is eliminated to produce a second precipitate of solids that were dissolved in the alcohol. This second precipitate is then dissolved in an organic solvent to produce a composition suitable for inclusion in a dermatological or cosmetic preparation.
