The paramagnetic metal complex has a good effect on raising the early diagnosis levels of diseases of liver and kidney organs, is about 2 times the relaxation rate of dotarem, has very long targeted radiography imaging time, can be easily prepared into a solution with required concentration for intravenous injection, is suitable for sterilizing and disinfecting with a hot pressing method, can be selectively identified by an asialoglycoprotein receptor on a liver parenchyma surface, and has high selectivity on livers of human beings or other mammals.

The invention discloses a technique which prepares high-purity arabogalactan from a dahuricia larch. The arabogalactan has effects of obvious increase of boy immunity, tumor resistance, mutation resistance, reduction of blood lipid, virus resistance and enhancement of the immunoreactive activity of monocytes, macrophages, T cells and natural killer cells in immune antigens. The preparation technique includes ultrasonic-assisted extraction, ultrafiltration concentration, washing purification and drying. The preprocessed dahuricia larch as a material is mixed with a designated solvent, extraction process is fulfilled in the energy field of ultrasonic energy, so that the crude extractant A of the arabogalactan is produced. The invention applies adsorbent to absorb the non-saccharide ingredients in the crude extractant A, and applies membrane separation techniques, such as microfiltration, ultrafiltration, etc., to separate arabogalactan, and after removing impurities in the crude extractant, small-molecule pigments and partial solvent, the purified arabogalactan solution D. The purified arabogalactan solution D is refrigerated and dried in order to obtain the white or light yellow powdery high-purity arabogalactan, and purity can reach over ninety five percent.

A composition is provided for reducing bacterial growth in food products. The composition includes a wood extract containing polyphenols and may contain arabinogalactan. The composition suppresses or prevents the growth of E. coli and of Salmonella sp. The wood extract imparts little or no residual taste to the food product. However, it can readily be removed if desired by washing before use of the food. The composition may be essentially arabinogalactan-free to further reduce bacterial growth.

The invention discloses a freezing liquid for preserving embryo, especially a freezing liquid for preserving sampled embryo. The freezing liquid comprises ethylene glycol and sucrose, and is characterized by comprising 0.4-5g of arabinogalactan, 75-85mL of ethylene glycol, 30-40g of sucrose, and 910-930mL of PBS buffer solution containing 0.0021 g/mL bovine serum albumin (BSA). A preparation method of the freezing liquid comprises the steps of dissolving ethylene glycol, sucrose and arabinogalactan in the BSA-containing PBS buffer solution. The freezing liquid fully utilizes synergic effects of the four components that ethylene glycol, sucrose, arabinogalactan and bovine serum albumin are coordinated and supported one another, and has higher development rate of thawed sampled embryo in comparison with conventional ethylene glycol freezing liquid.

The invention discloses a method for extracting arabinogalactan and dihydroquercetin from dahurian larch. The method is characterized in that dahurian larch is taken as a raw material and is subjected to supersonic extraction with an ethanol solution; solid and liquid are separated from each other through filtering, so that an extracting solution is obtained; absolute ethyl alcohol is fed into the extracting solution till polysaccharide is sufficiently settled; the polysaccharide is subjected to high-speed centrifugation; precipitation, refrigeration and drying are performed, so that dahurian larch arabinogalactan crude extract is obtained; ethyl alcohol in supernate is concreted till solid matter is obtained; the solid matter is dissolved through hot water and then is enriched through macroporous adsorption resin; elution and recrystallization are performed, so that dihydroquercetin extract is obtained. The method has the main characteristics that the raw material is not required to be dried and directly used, the energy consumption is low, by adjusting the content of ethanol in the ethanol solution for extracting, arabinogalactan and dihydroquercetin are simultaneously extracted, the production cost is low, energy consumption is reduced, the yield of products is high, the process of purification performed by the macroporous adsorption resin is pollution-free, all solvents can be recycled, and the method is convenient for industrial scale production.

The invention discloses a method for extracting larch arabinogalactan. The method is characterized by comprising the following steps: crushing larch wood chips, and soaking with petroleum ether for degreasing; extracting arabinogalactan from the degreased larch wood powder with a chlorinated 1-butyl-3-methylimidazole ionic liquid solution to obtain extract; adding the extract into an ethanol solution to obtain a precipitate; filtering the precipitate; and drying the filter cake to obtain the larch arabinogalactan, wherein the ionic liquid is used for extracting the larch arabinogalactan and has the characteristics of stable property, no volatilization or burning explosion and the like. The technology has the advantages of little loss, low energy consumption, simplicity and convenience in operation, easiness in industrialization and the like; the arabinogalactan filter cake is obtained from the extract by an ethanol precipitation method; the recycled ethanol can be used again, and thus the production cost is reduced; and a new idea is provided for efficient and green large-scale production of arabinogalactan and comprehensive utilization of larch resources.

The object is to provide: a safe immunomodulating agent which can be used as a pharmaceutical or a food material; a method for production of the immunomodulating agent; and a novel application of a coffee extract residue. Disclosed is an immunomodulating agent comprising a coffee extract as an active ingredient. Preferably, the coffee extract is an extract containing arabinogalactan. The immunomodulating effect of the immunomodulating agent relies on the promotion of the proliferation of an immunocompetent cell such as a macrophage. The immunocompetent cell is preferably any one selected from a macrophage like strain RAW264 or J774.1, a murine splenocyte, a murine peritoneal macrophage and a murine dendrocyte. A composition containing the immunomodulating agent can be used as a composition such as a pharmaceutical composition, a food composition and a cosmetic composition.
