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.
