The invention discloses ailanthus altissima extract nano-emulsion and a preparation method and application thereof, the nano-emulsion comprises ailanthus altissima extract, holly essential oil, an emulsifier and water, and the ailanthus altissima extract is ailanthus altissima bark extract; the preparation method comprises the following steps: uniformly mixing the ailanthus altissima extract, the holly essential oil and the emulsifier as an oil phase, dropwise adding water into the oil phase while stirring, and continuously stirring after dropwise adding to obtain the uniform ailanthus altissima extract nano-emulsion. Compared with the ailanthus altissima extract, the ailanthus altissima nano-emulsion has the advantages that the insecticidal effect is obviously improved, the obvious insecticidal effect on various pests is achieved, the plant source pesticide is good in environmental compatibility, diversified in biological activity, safe to higher animals and natural enemies and not prone to generating drug resistance to pests.

This invention discloses a natural plant-extracted biological insecticide and its preparation and application methods, belonging to the field of agricultural biotechnology. The insecticide uses cypress leaves, stemona root, clematis root, pinellia root, and ailanthus leaves as raw materials, prepared through boiling, cooling, filtration, sealed maturation, double-barrel water bath temperature gradient concentration, and pasteurization. This insecticide kills pests by sealing their spiracles and rapidly penetrating their bodies, causing suffocation. It primarily works through contact, exhibiting good residual effect, low resistance development, no chemical residues, and is environmentally friendly. The preparation process is mild, maximizing the retention of heat-sensitive active ingredients. The product is highly stable and low-cost, particularly suitable for controlling Diptera, Coleoptera, Orthoptera, Hemiptera, and / or Lepidoptera pests.

The invention belongs to the technical field of plant tissue culture, and particularly discloses a somatic embryogenesis and plant regeneration method for ailanthus altissima. The method comprises the following steps: (1) taking a leaf axis, a small leaf or a compound leaf of an ailanthus altissima aseptic seedling as an explant, inoculating the explant on an embryogenic callus induction culture medium, and culturing to form an embryogenic callus; (2) inoculating the embryogenic callus obtained in the step (1) to a somatic embryo induction culture medium for culturing; and (3) selecting embryogenic calluses with good growth vigor and somatic embryos on the surfaces, and subculturing the embryogenic calluses in a somatic embryo germination culture medium to obtain somatic culture seedlings. According to the invention, a somatic embryo regeneration system of Ailanthus altissima is established for the first time, and the problem that the embryonic callus and somatic embryo of Ailanthus altissima are difficult to induce is effectively solved.

The invention provides a natural plant extract for treating chronic obstructive pulmonary disease as well as a preparation method and application thereof, and relates to the technical field of medicines. The natural plant extract comprises the following raw materials in parts by weight: 6-10 parts of a cynanchum chinense extract, 5-7 parts of a polygonum palmatum extract, 4-6 parts of an ailanthus altissima extract, 1-3 parts of an elsholtzia calyx extract and 1-3 parts of a streptocaulon griffithii extract. The natural plant extract disclosed by the invention can reduce expression levels of inflammatory factors TNF-alpha, IL-1beta and IL-17A of the chronic obstructive pulmonary disease, can reduce pause time at the end period of expiration of the lung, 50% expiration flow rate and airway stenosis index, can improve the maximum expiration volume of the lung, and can improve the lung function of a model mouse with the chronic obstructive pulmonary disease; a new natural medicine is provided for treating the chronic obstructive pulmonary disease, and the medicine is remarkable in curative effect, safe, non-toxic, free of side effects and good in application prospect.

The application discloses application of a triperpenoid compound of Ailanthus-type or a glycoside thereof in preparation of a liver-protecting medicine. The application also performs glycosylation modification on the triperpenoid compound of Ailanthus-type to obtain a liver-protecting active triperpenoid glycoside of Ailanthus-type. The compound has potential application value in preparation of a medicine for preventing or treating liver diseases.

The application discloses a method for preparing disease-preventing medium-element water-soluble fertilizer by using Chinese herbal medicine extract, and belongs to the technical field of water-soluble fertilizer. The method comprises the following steps: mixing calcium nitrate (tetrahydrate), anhydrous calcium chloride, magnesium sulfate heptahydrate, magnesium nitrate hexahydrate, anhydrous potassium sulfate, boric acid, white carbon black, citric acid, polyvinyl pyrrolidone and Chinese herbal medicine extract mixture, adding into water and stirring uniformly, discharging and packaging, and the disease-preventing medium-element water-soluble fertilizer is obtained; the Chinese herbal medicine extract mixture is prepared by using Ailanthus altissima swingle fresh leaves, broken powder of Vitex negundo seed, Kigelia japonica flower, dry root of Stemona sessilifolia and Periwinkle whole grass, water extraction, and freeze-drying; by compounding Ailanthus altissima, Vitex negundo, Kigelia japonica, Stemona sessilifolia and Periwinkle five kinds of Chinese herbal medicine extract, multi-target point synergistic inhibition of bacteria is formed, meanwhile, medium-element nutrient supply is met, and the integration of nourishment supply and disease prevention is realized.

The invention provides application of ailanone in inhibiting HK2 regulation glycolysis and treating metabolic inflammation cross diseases, and belongs to the technical field of biological medicines. The invention reveals for the first time that ailanone (AIL) can significantly alleviate sepsis-related myocardial damage by targeting HK2, and has good biological safety. After the AIL is used for treating an animal model, the heart blood pumping function can be remarkably recovered; the level of myocardial injury markers is reduced; the tissue damage is obviously relieved. Meanwhile, a staining experiment proves that the AIL can effectively reduce the LPS-induced myocardial cell apoptosis rate and obviously reduce the Ly6G level, and proves that the AIL can improve cell apoptosis and immune injury. The ailanthus altissima ketone inhibits HK2 to regulate glycolysis, breaks the metabolic abnormality loop in the SCM pathogenesis process, and is suitable for treatment of multiple metabolic inflammation cross diseases such as sepsis, myocarditis, inflammatory cardiovascular diseases and the like.
