Method for preparing salvianolic acid A by catalytically converting salvianolic acid B

The invention discloses a method for preparing salvianolic acid A by catalytically converting salvianolic acid B. The method is characterized in that the converted raw material is a salvia miltiorrhiza aqueous extract (salvianolic acid B=>50%) primarily purified through combined chromatography; the concentration of the raw material salvianolic acid B is 0.5-2%; urea is taken as the catalyst; the mole ratio of urea to the salvianolic acid B is 0.3-0.7; the conversion reaction temperature is 100-125 DEG C; and the reaction time is 3-6 hours. The method has the following beneficial effects: urea is taken as the catalyst, thus greatly shortening the time for which the salvianolic acid B is in easily destroyed state and remarkably increasing the yield of the salvianolic acid A; the primarily purified salvia miltiorrhiza extract is taken as the converted raw material, thus not only removing the metal ions which are not beneficial to conversion but also removing most colloid-like impurities and frontal impurities which are not beneficial to following separation of the salvianolic acid; and the directional conversion rate of the salvianolic acid B to the salvianolic acid A prepared by the method is not less than 10% and even reaches 60%.

Chinese medicinal preparation for treating bone fracture and preparation method thereof

The invention relates to a Chinese medicinal preparation for treating bone fracture, which is prepared from 84 raw medicinal materials such as radix astragali, Chinese angelica, rehmanniae vaporata, rehmanniae praeparatum, suberect spatholobus stem, human placenta and the like. The medicament can be made into an oral preparation and external application preparation. A preparation method comprises the following steps: preparing an aqueous extract of the raw medicinal materials, and preparing an oral solution and a spraying agent from the aqueous extract; and preparing extracting pulvis from the aqueous extract, and preparing granules, pills, medicinal granules, tablets or capsules from the extracting pulvis. Raw medicinal powder also can be ground into raw powder pulvis which can be prepared into the granules, the pills, the medicinal granules, the tablets or the capsules, or the raw powder pulvis is prepared into external application ointment. In addition, the raw medicinal materials also can be infused to form medicinal liquor. The Chinese medicinal preparation has good curative effect on bone fracture diseases of different types, is mainly used for treating different types of fracture, muscles and bones breakage, traumatic injury, new and old incised wound and gunshot wound, bleeding and blood stasis which are caused by traumatism and other symptoms, and has the obvious curative effect on rheumatoid arthritis. The Chinese medicinal preparation is prepared from pure Chinese medicaments, and has convenient use, safety, reliability, no toxic or side effect and long-term use.

Chinese medicinal preparation for treating diabetes and preparation methods thereof

The invention relates to a Chinese medicinal preparation for treating the diabetes, which is prepared from 47 raw material medicaments in part by weight: astragalus, siberian solomonseal rhizome, common yam rhizome, cornus fruit and the like. A preparation method 1 for the Chinese medicinal preparation comprises the following steps: (1) preparing aqueous extract of the raw material medicaments; (2) preparing oral liquid from the aqueous extract; (3) drying and crashing the aqueous extract obtained by the step (1), and passing the powders through a screen to prepare medicament extract powders; and (4) preparing tablets, granules, pills, soluble granules or capsules with the medicament extraction powders. A preparation method 2 for the Chinese medicinal preparation comprises the following steps: (1) drying fresh pig pancreas and grinding the fresh pig pancreas into powders; (2) crushing other raw material medicaments, passing the powder through a screen to prepare medicament powders; (3) uniformly mixing the pig pancreas powders and the medicament powders, disinfecting and sterilizing to obtain raw powders; and (4) preparing oral tablets, granules, pills, soluble granules or capsules with the raw powders. Based on the principle of monarch, subject, assistant and envoy, the medicament of the invention has synergistic effect, addresses both the symptoms and root causes, has better curative effect on the diabetes, and has obvious effect of treating serious diabetes. The raw medicinal materials adopted by the Chinese medicinal preparation are common Chinese medicaments, have low production cost and have no toxic or side effects basically.

Preparation of brightness stabilization agent for lignin containing pulp from biomass pyrolysis oils

A process for producing a brightness stabilization mixture of water-soluble organic compounds from biomass pyrolysis oils comprising:a) size-reducing biomass material and pyrolyzing the size-reduced biomass material in a fluidized bed reactor;b) separating a char / ash component while maintaining char-pot temperatures to avoid condensation of pyrolysis vapors;c) condensing pyrolysis gases and vapors, and recovering pyrolysis oils by mixing the oils with acetone to obtain an oil-acetone mixture;d) evaporating acetone and recovering pyrolysis oils;e) extracting the pyrolysis oils with water to obtain a water extract;f) slurrying the water extract with carbon while stirring, and filtering the slurry to obtain a colorless filtrate;g) cooling the solution and stabilizing the solution against thermally-induced gelling and solidification by extraction with ethyl acetate to form an aqueous phase lower layer and an organic phase upper layer;h) discarding the upper organic layer and extracting the aqueous layer with ethyl acetate, and discarding the ethyl acetate fraction to obtain a brown-colored solution not susceptible to gelling or solidification upon heating;i) heating the solution to distill off water and other light components and concentrating a bottoms fraction comprising hydroxyacetaldehyde and other non-volatile components having high boiling points; andj) decolorizing the stabilized brown solution with activated carbon to obtain a colorless solution.
