The invention belongs to the technical field of traditional Chinese medicine modernization and medicine development, and particularly relates to a uric acid reducing product based on folium apocyni veneti extract and application of the uric acid reducing product. The core active component of the product is the folium apocyni veneti extract. In-vivo experiments prove that the extract can remarkably reduce the blood uric acid level and xanthine oxidase (XO) activity of a mouse with hyperuricemia. Six active ingredients entering blood are identified through in-vivo metabolism research. The direct interaction between the main active component and the target protein XO is verified from the molecular level through molecular docking, surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) technologies, and the uric acid reducing action mechanism of the compound is completely clarified. The invention provides a scientific basis and a high-quality product for developing a new uric acid-reducing drug effect of the folium apocyni veneti.

The application discloses a preparation method of long apocynum venetum wet-spun yarn. First, a base copolymer is prepared by free radical copolymerization of 2-hydroxyethyl methacrylate, 2-(dimethylamino) ethyl methacrylate and glycidyl methacrylate, and then reacted with 1-bromododecane to obtain an antibacterial component containing a quaternary ammonium salt antibacterial structural unit, a hydroxyl compatible structural unit and an epoxy anchoring structural unit; then the antibacterial finishing liquid is prepared, apocynum venetum fibers are impregnated, liquid rolled, dried, opened, carded and drawn, then wetted, wet-spun, dried and set, and wound to obtain long apocynum venetum wet-spun yarn. The application can improve the inherent stability of the antibacterial component in the wet spinning process, and has antibacterial durability, spinnability and yarn quality.

The application discloses a cultivation method of apocynum venetum and a special growth aid. After the apocynum venetum grows to a height of 10-30 cm, water is poured 3-4 times per month, and once fertilization is selected in the 3-4 times of water pouring per month; 5-12 Kg of urea and 3-5 Kg of potassium dihydrogen phosphate are applied per mu each time, and the growth aid is applied once 2-4 days after the water pouring and fertilization, and is sprayed on the apocynum venetum plants; the growth aid comprises the following substances: 0.5-1 parts by weight of naphthalene acetic acid, 2-3 parts by weight of fulvic acid, 2-3 parts by weight of titanium dioxide and 1-2 parts by weight of seaweed extract; the growth aid is diluted by 300-500 times for spraying, and 20-70 Kg is applied per mu. The application has the advantages that not only can apocynum venetum leaves with higher chlorophyll and effective component contents and better quality be obtained, but also the adhesion degree of the apocynum venetum skin and the apocynum venetum bone can be effectively reduced, so that the apocynum venetum skin can be easily peeled from the apocynum venetum stem, the peeling difficulty of the apocynum venetum is effectively reduced, the utilization rate of the apocynum venetum skin is improved, and the economic benefits of large-scale planting of the apocynum venetum are greatly improved.

The invention discloses a patch for treating gout based on folium apocyni veneti and a preparation method of the patch, and belongs to the technical field of folium apocyni veneti. Comprising a backing layer, an adhesion layer and an anti-sticking layer, wherein the adhesion layer comprises the following components in percentage by weight: 5-10% of folium apocyni veneti general flavone extract; 1-3% of a transdermal absorption enhancer; 2-5% of an auxiliary material; the balance of adhesive matrix; the preparation method of the folium apocyni veneti total flavone extract comprises the following steps: crushing dried folium apocyni veneti, sieving, and carrying out ultrasonic extraction by using an ethanol solution; filtering and concentrating under reduced pressure; and purifying through a macroporous resin column to obtain the apocynum venetum leaf general flavone extract. The purification process is as follows: the used adsorption resin is selected from AB-8 type macroporous resin; the concentration of the added sample is 1-4 mg / mL, and the pH value is 4.8-5.2; the sample loading amount is 2.0-3.0 mL / g resin mass, and the adsorption time is 3-6 hours; and eluting with an ethanol solution which is 2-4 times of the column volume, and analyzing for 1.5-3.0 hours.

The invention discloses an apocynum venetum pelletized seed coating structure and application thereof, belongs to the field of apocynum venetum breeding, and aims to solve the problem that mechanical seeding operation of pelletized apocynum venetum seeds is difficult to realize due to limitation of geographical conditions in high mountain areas such as Xinjiang. The invention relates to an apocynum venetum seed pellet which comprises a paper coated shell, hollow plant straw and a plurality of pelletized apocynum venetum seeds, the paper coated shell is spherical, the pelletized apocynum venetum seeds are located at the inner bottom of the paper coated shell, and the remaining space in the paper coated shell is filled with the hollow plant straw. By adopting the application, a planter can carry out loading in the form of a backpack, and the apocynum venetum pelletized seed coating structure can be put into a to-be-repaired region through the slingshot in the to-be-repaired mountainous area, which cannot be realized by the existing pure pelletized apocynum venetum seeds. In addition, a plurality of apocynum venetum pelletized seed coating structures are manually put into a to-be-repaired region, so that the formation of block-connected apocynum venetum populations is facilitated.
