Abstract: The invention discloses a technology for producing ester of carboxylic acid using cellulosic biomass as starting material. This technology comprises the following key steps: converting all of the organic polymers, including such high molecular-weight polymers as carbohydrate components and lignin, in cellulosic biomass into water soluble, small molecular organics completely in relatively short time under relatively mild conditions; separating the resultant water soluble compounds containing aromatic rings by adjusting the acidity/basicity of the reaction solution or by using adsorption resin; and converting the water soluble compounds containing aromatic rings into ester of carboxylic acid by hydrogenation and esterification in a corresponding alcohol solution.

Abstract: A method of refining cellulosic biomass, including synchronous hydrolyzation of at least 85 wt % organic polymers, based on the total weight of the cellulosic biomass, in the cellulosic biomass into small molecular organic compounds. The synchronous hydrolyzation is catalytic hydrolyzation for which the catalyst used is a substance represented by L-M-S-H or L-M=S, wherein “M” represents metal, carbon or silicon, “S” represents a heteroatom, “L” represents one or more ligands, and “H” represents hydrogen.

Abstract: A continuous reaction system is provided, which specifically relates to a continuous reaction system comprising subcritical and/or supercritical liquid as solvents and a reactant as solid. The invention can effectively prevent cavitations in the reaction system effectively, and realize maximum conversion of the solid reactant material.

Abstract: The present invention discloses a process for producing Simvastatin and intermediate thereof. The present invention uses inexpensive and easily available reagents, its condition is mild, and it leaves out the protective and deprotective steps, which are necessary in prior methods. Compared with prior art, the esterifying condition in 8-position is greatly simplified.

Abstract: The present disclosure provides a combined medicament for reducing blood fat with safety and high efficiency, the active ingredients of which include an agent for lowering blood fat such as statins; an agent for protecting and repairing liver such as silymarin; an agent for protecting kidney, heart, blood vessel or muscle such as coenzyme Q10 and various excipients desired for producing medicaments. The present disclosure can safely and reliably lower the concentration of cholesterol in the blood; protect blood vessels of heart and brain and provide them with nutrition; protect and repair other relevant causes of disease which result in the increasing of blood fat; and lower, even eliminate the side effects of the damage of statins on muscle and liver.

Abstract: The invention relates to statin compounds, and it discloses novel small molecule compounds, i.e., huvastatins, which are classified into I, II, and III. The invention also provides the preparation methods thereof and the formulations comprising the huvastatin as active ingredient. The present compounds can be used at lower dosage compared to the existing statin compounds, and also can help to control the desired blood lipid levels of the patients with hyperlipidemia. Huvastatin of the invention exhibits suitable hydrophilicity, strong potency and therapeutical effect for reducing lipid levels, and lower dosage.
