This invention relates to the field of veterinary drug formulation and new feed additive technology, and proposes a compound emulsion based on hydroxypropyl chitosan-encapsulated essential oil-phytosterols, its preparation method, and its application. The compound emulsion is composed of the following raw materials in weight percentages: 10%–15% hydroxypropyl chitosan essential oil-encapsulated emulsion, 6%–9% phytosterol liposome dispersion, 6%–10% medium-chain triglycerides, 1.5%–2.5% beeswax, 2%–3% hydrogenated soybean lecithin, 3%–4% polysorbate 80, 0.3%–0.5% xanthan gum, 5%–7% glycerol, 3%–5% glucose, 0.05%–0.1% potassium sorbate, 0.005%–0.008% antioxidant, and the balance being water. This technical solution solves the problem of poor treatment efficacy for bacterial diseases in calves in related technologies.

The invention discloses a dexheptane structure prostacyclin-loaded nano transdermal patch and a preparation method, the dexheptane structure prostacyclin-loaded nano transdermal patch comprises 10-30 parts of dexheptane precursor liposome, 10-20 parts of a prostacyclin nano-structure lipid carrier and 50-70 parts of an acrylate pressure-sensitive adhesive, the dexheptane precursor liposome comprises 8-12 parts of dexheptane and 36-54 parts of hydrogenated soya bean lecithin, and the prostacyclin nano-structure lipid carrier comprises a prostacyclin nano-structure lipid carrier and an acrylate pressure-sensitive adhesive. The prostacyclin injection comprises the following components in parts by weight: 36-54 parts of mannitol, 80-240 parts of absolute ethyl alcohol, 150-450 parts of purified water, 0.150-0.200 part of prostacyclin, 80-150 parts of glyceryl monostearate, 20-50 parts of oleic acid, 10-30 parts of soybean lecithin and the balance of purified water, wherein the total amount of the prostacyclin injection, the glyceryl monostearate, the oleic acid, the soybean lecithin and the purified water is 1000 parts. According to the invention, the dextroheptane is used as a functional penetration enhancing component in transdermal drug delivery, the dextroheptane and the prostacyclin are synergistically integrated in the nano-lipid carrier, the transdermal penetration rate and the cumulative penetration amount of the prostacyclin are improved, the treatment effect is improved, and continuous and stable release of the prostacyclin is realized under the combined action of the nano-structure lipid carrier and the patch matrix.

The present application relates to the field of cosmetic technology, in particular to a liposome for encapsulating ergothioneine, a preparation method and application thereof, comprising a phospholipid bilayer formed by compounding soybean lecithin and hydrogenated soybean lecithin, and ergothioneine encapsulated in the phospholipid bilayer; the mass ratio of the soybean lecithin to the hydrogenated soybean lecithin is 5:5-8:2; the intermembrane space of the phospholipid bilayer is filled with tocopherol and polyglycerol-10 laurate. The product is mild and can simultaneously solve the degradation odor of ergothioneine, balance the stability and transdermal permeability, meet the stringent requirements of edible grade safety standards for sensitive parts such as the lip mucosa, and has extremely high market promotion value.

The invention discloses an alligator penis active peptide and application thereof in thrombus treatment, and belongs to the technical field of biological medicine. The invention provides an active peptide extracted from alligator penis aiming at the problems of side effects of existing antithrombotic drugs and blank research on active substances of the alligator penis. The active peptide can effectively inhibit carrageenan-induced mouse tail thrombosis, the action mechanism of the active peptide is related to anti-platelet aggregation and anti-inflammatory dual pathways, and the active peptide shows good safety. The invention provides a phospholipid composite liposome containing the active peptide, the active peptide and hydrogenated soybean lecithin, cholesterol and the like in a specific proportion are constructed into a nano liposome, and a phospholipid combination with high and low phase transition temperatures is preferably adopted, so that the bioavailability and targeting property of a medicine are improved. According to the preparation, the synergistic effect of decrement and synergism and the synergistic effect of the same amount in an animal model is achieved, and a new candidate substance and preparation scheme is provided for developing novel, efficient and safe antithrombotic drugs or functional products.

The present application provides a liposome-encapsulated whitening composition, a preparation method and an application thereof, and belongs to the field of medical, dental or cosmetic preparations. The components of the present application are 4-butyl resorcinol, tranexamic acid, alpha-arbutin, coenzyme Q10, Ceylon cinnamon oil, sweep leaf Australian tea branch / leaf oil, hydrogenated soybean lecithin and a humectant. The present application is compounded with a variety of different whitening components, covering the three major pathways of "inhibiting tyrosinase activity, inhibiting melanin transfer and accelerating melanin metabolism" for melanin production; in line with the modern multi-target whitening trend. At the same time, the additional plant essential oil has the effect of promoting penetration and strengthening the inhibition of tyrosinase; at the same time, the liposome-encapsulated preparation solves the problem of mutual incompatibility between raw materials and increases the transdermal absorption rate and reduces the irritation. It can be added to a variety of different specific products, such as serums, creams, lotions, etc.
