Disclosed are glycopeptide compounds having activity of resisting drug-resistant bacteria, conforming to glycopeptide compounds represented by general formula (I). The present invention also provides a preparation method for and an application of the glycopeptide compounds. Upon testing, compared with a second-generation glycopeptide drug oritavancin, the glycopeptide antibiotic compounds have higher inhibition activity on drug-resistant bacterial strains, especially MRSA or VRE. Further testing shows that most of the glycopeptide compounds have safety higher than that of oritavancin and can be prepared into drugs for treating or preventing diseases caused by various bacterial infections, such as skin and soft tissue infections, meningitis, sepsis, pneumonia, arthritis, peritonitis, bronchitis, and empyema.

A fixed bed decolorization process for an unsaturated fatty acid, comprising: a polyunsaturated fatty acid or a polyunsaturated fatty acid solution is either passed directly through a fixed bed filler or circulated in the fixed bed filler, a colorless or light-colored polyunsaturated fatty acid product is ultimately produced, at the same time, other than the color, other qualities of the polyunsaturated fatty acid remain unaffected. The decolorization process allows continuous operation or intermittent operation. The fixed bed filler comprises one or a mixture of several among activated carbon, diatomaceous earth, white clay, silicone, and an ion-exchange resin. A top or a middle or a bottom or a combination thereof is employed to feed a polyunsaturated fatty acid feedstock or a polyunsaturated fatty acid feed solution. The filler in the fixed bed can be used repeatedly. The filler can be reused after being washed when decolorization effects thereof become deteriorated or ineffective.

The present invention relates to a method for preparing a carotenoid oil suspension with low viscosity and high fluidity. The method includes the steps of mixing carotenoid crystals with tetrahydrofuran, heating the resulting mixture to a reflux temperature of about 50˜70° C. under stirring, and filtering-the resulting solution to remove fat-soluble fibers. The resulting filtrate is then condensed to dryness, mixed with a ketone solvent, heated to a reflux temperature of about 60˜80° C., and filtered to remove non-soluble phospholipids. The filtrate obtained is condensed to a residue, and absolute alcohol is added to the residue, and then crystallized under stirring at room temperature. The resulting crystals are filtered and dried to-provide carotenoid crystals. The carotenoid crystals are ground and mixed with plant oils to provide a carotenoid oil suspension with low viscosity and high fluidity, which provides easy filling, for example, into capsules.

Abrégé
This invention has disclosed a method for preparation of food-grade zeaxanthin through chemical isomerizaton reaction from lutein. The technical issues to be solved in this invention are quite low product yield obtained with existing methods, need of purification treatment process, and inadaptability to industrialized production. The technical schemes of this invention are: a. Mix xanthophyll crystal or its fatty acid ester with food-grade glycol or propylene glycol, for full dissolution under 60-90° C. temperature. Add organic alkali into the mixed liquor acquired from step 1, for isomerization reaction to take place under inertial environment. c. Dilute the reaction solution gained from step b with the mixed solution of deionized water and ethanol, and separate the obtained crystal with conventional separating method. d. Vacuum dries the acquired crystal from step c, to get the zeaxanthin crystal. Glycol or propylene glycol is used in this invention for isomerization reaction under inertial environment after it has fully dissolved raw material under proper temperature. The product yield is reachable to more than 60%, very adaptable to industrialized product, without the need for further purification treatment.
