350 results about "Magnolol" patented technology

Magnolol is an organic compound that is classified as lignan. It is a bioactive compound found in the bark of the Houpu magnolia (Magnolia officinalis) or in M. grandiflora. The compound exists at the level of a few percent in the bark of species of magnolia, the extracts of which have been used in traditional Chinese and Japanese medicine. In addition to magnolol, related lignans occur in the extracts including honokiol, which is an isomer of magnolol.

Composition for prevention and treatment of diabetic complication

The present invention relates to a composition for the prevention and treatment of diabetic complications, which contains an extract obtained by: crushing and drying any one selected from Euphorbiae radix, gingered Magnolia bark, parched Puerariae radix and Glycyrrhizae radix; extracting the dried herbal material with alcohol or aqueous alcohol solution: filtering the extract; and concentrating the filtrate under reduced pressure. Alternatively, the composition contains a mixture of extracts from Euphorbiae radix, gingered Magnolia bark, parched Puerariae radix and Glycyrrhizae radix, the amount of each of the herbal extracts being 5-85% by weight based on 100% by weight of the herbal extract mixture. Alternatively, the composition contains magnolol obtained by: extracting Magnolia bark with aqueous 80% ethanol solution at ambient temperature for 24 hours; systematically separating the extract in the order of normal-hexane, ethyl acetate and normal-butanol; selecting the normal-hexane layer and separating the selected layer into pre-fractions by normal silica gel chromatography; comparing the pre-fractions with the standard form magnolol on TLC to determine a magnolol-enriched fraction; and separating magnolol from the magnolol-enriched fraction by silica gel column chromatography.

Method for extracting honokiol and magnolol from mangnolia officinalis crude extract

The invention discloses a method for extracting honokiol and magnolol from a mangnolia officinalis crude extract. In existing methods of separating the honokiol from the magnolol in the mangnolia officinalis crude extract, in some methods, the cost is too high, the production volume is low, and mass production is not easy to achieve. In the method disclosed by the invention, by means of the characteristic that the magnolol and the honokiol contained in the mangnolia officinalis crude extract can be completely separated in a weak polar solution under an alkaline condition with certain concentration, the magnolol is extracted from a mixed solution by using a weak alkaline solvent, the honokiol is left in the solution, the honokiol is extracted by a strong alkaline solution, some oily impurities are left in an organic solvent layer, then acid regulation and precipitate out are carried out respectively, at this time, the contents of the honokiol and the magnolol in the obtained coarse-grain are greatly improved. The method disclosed by the invention is simple and feasible in separation and purification process and is suitable for large-scale industrial production, and the prepared magnolol and honokiol can be used for developing new medicines with single components.

Method for preparing stomach pill of aucklandia and amomum fruit

The invention provides a preparation method of stomachic pill with cyperus and amomum, including following steps: banksian rose, amomum fruit, astraolylis lancea formalyrata, dried old orange peel, tuckahoe, pinellia(processed), autgrass galingale rhizome(processed with vinegar), fruit of immature citron(sauted), round cardamom(decladded), bark of official magnolia( baked with ginger),patchouli and liquorice are respectively pulverized and mixed at first, then through the steps such as adding adhesive, granulating, drying, finishing granule, pelleting and lagging cover orderly, the product can be obtained; the adhesive is decoction solution of ginger and jujube. The preparation method has the advantages of simple technology and convenient operation, moreover, the finished product has steady quality, and compared with the former stomachic pill with cyperus and amomum, the stomachic pill with cyperus and amomum can shorten dissolving time by over 70 to 90 percent, thereby the medicine can be absorbed faster, and the contents of magnolol and honokiol are higher, thus solving the problem of nonuniform size of the pellet prepared by the water-pill method, and the dosage of the medicine can be more exact; at the same time, the invention also increases rate of finished products at one time.

Method for extracting total magnolol according to alcoholic-alkaline method

The invention provides a method for extracting total magnolol according to an alcoholic-alkaline method. The method comprises the following steps: firstly drying magnolia bark, smashing the magnolia bark and screening the magnolia bark through a 100 mesh screen, then preparing alcoholic-alkaline solution with 0.01 to 0.025N alkalinity through 50 to 70 percent alcoholic solution, mixing the magnolia bark powder and the alcoholic-alkaline solution according to the ratio of sample to solution (g / ml) being 1:10 to 1:20, performing ultrasonic extraction for 20 to 40 min, performing centrifugal separation, obtaining magnolia bark residue and alcoholic-alkaline solution I containing total magnolol, performing ultrasonic extraction again, concentrating the alcoholic-alkaline solution, adjusting the pH value of the concentrated solution to 2 to 3 through hydrochloric acid, refrigerating the concentrated solution for 6 to 8h at 2 to 6 DEG C, obtaining sediment, washing the sediment through water to be neutral, and the like. The method extracts the total magnolol according to the alcoholic-alkaline method by combining magnolol and physical and chemical properties of the magnolol, and has the advantages that the extraction efficiency is high, the energy consumption is low, the production is reduced, and the method is simple and efficient.
