    摘要: A method for preparation of Timosaponin BII, which uses Chinese traditional medicine Rhizoma Anemarrhenae or fresh rhizoma or fibrous root of Anemarrhena asphodeloides Bge. as raw material, and comprises isolation of Timosaponin BII by one or more processes selected from solvent extraction, resin adsorption, polyamide chromatography, reversed phase column chromatography, Sephadex LH-20 column chromatography, etc, combining with conventional drying method such as reduced pressure drying, freeze drying, spray drying, and so on. Timosaponin BII obtained by the present method is of over 90% purity, and the method is simple, practicable and suitable for industrial production.

    摘要: The present invention relates to a pharmaceutical composition for combating a thrombotic disease and a method for making the same and a use thereof. The pharmaceutical composition mainly comprises timosaponin AIII and timosaponin BII, and optionally pharmaceutically acceptable excipients, characterized in that the amount of timosaponin AIII is greater than or equal to the amount of timosaponin BII. The present invention further relates to a use of timosaponin AIII and timosaponin BII in manufacturing a medicament or product for the prophylaxis or to treatment of a thrombotic disease. The present pharmaceutical composition can not only bring about effects of prophylaxis or treatment of a thrombotic disease, but also alleviate blood bleeding or bleeding tendency in patients.

    摘要: The invention provides a synthetic route from sarsasapogenin to timosaponin BII and related compounds. A diketone intermediate is provided, which can advantageously be used for in situ assembly of complex sugar moieties of the desired glycone end product. The diketone compound is then selectively reduced using a borohydride reducing agent to form the desired end product, certain of the end products and intermediates are novel compounds perse.
