The invention relates to the technical field of fresh fruit and vegetable preservation, in particular to environment-friendly fruit and vegetable preservative paper. The environment-friendly fruit and vegetable preservative paper is formed by compounding an upper layer of single-piece wood pulp raw paper and a lower layer of single-piece wood pulp raw paper, wherein the upper-layer paper is bamboo carbon fiber paper; the lower-layer paper is traditional Chinese herbal medicine preservative paper; and the traditional Chinese herbal medicine preservative is formed by spray-coating the raw paper with one to two layers of traditional Chinese herbal medicine preservative liquid. The traditional Chinese herbal medicine components of the raw materials in the preservative liquid have an antibacterial synergistic effect, so the preservative liquid can improve bacteriostatic and preservative effects, is an efficient, broad-spectrum and non-toxic natural fruit and vegetable freshness-retaining preservative and avoids the safety problem of the chemical preservative in the use process. The raw paper is wood pulp paper and bamboo carbon fiber paper, can reduce the humidity of the fruit and vegetable storage space, is antibacterial and anti-mildew, can improve air cleanliness, has an excellent preservative effect, can be used repeatedly, has high degradability and is non-toxic and nuisanceless. The environment-friendly fruit and vegetable preservative paper has a wide application prospect and has an active effect on fruit and vegetable preservation and freshness retaining.

The invention discloses a natural edible liquid detergent which is prepared from the following components in percentage by weight: 20-35% of soapberry peel extracted solution, 15-25% of tea seed powder extracted solution, 1-5% of a thickening agent, 0.01-0.2% of a preservative, 0.01-0.05% of an essence and the balance of deionized water. The invention further discloses a preparation method of thenatural edible liquid detergent. The natural edible liquid detergent is prepared by extracting plants containing natural active ingredients, is scientific in formula proportion, does not contain any artificially synthesized chemicals, is high in dirt-removing power, is mild and non-irritant to human bodies, and does not have toxic or side effect.

The invention discloses an application of norharmane in improvement of antibiotic antibacterial activity. When norharmane is combined with antibiotic polymyxin B, imipenem-cilastatin sodium or levofloxacin for application, the antibacterial activity on drug-resistant pseudomonas aeruginosa can be enhanced, and a synergistic antibacterial effect can be generated. According to the method for obviously improving the killing capacity of the antibiotics on the drug-resistant pseudomonas aeruginosa, the dosage of the antibiotics required for achieving the same treatment effect is greatly reduced, and a research direction is provided for the development of new drugs and the new use of old drugs.

The invention discloses a trefoil toothpaste and a preparation method thereof. The toothpaste is calculated in parts by weight: it includes 3.4-17.8 parts of a mixed wall-broken stock solution and toothpaste paste bases such as xanthan gum and carrageenan; the mixed wall-broken stock solution consists of three Composition of Yeqing, green tea leaves and Panax notoginseng, the weight of the three is 3-15 parts of Sanye Qingxian, 0.3-2 parts of green tea leaves, and 0.1-0.8 parts of Sanqi. The toothpaste uses spectrum sterilization and ultra-low constant temperature vibration The mixed wall-breaking stock solution is obtained by breaking the wall and micro-grinding, and the cell wall-breaking rate is over 98.5%. At the same time, under the condition of temperature control, it is combined with the toothpaste paste matrix. The micro-grinding method can obtain the mixed wall-broken stock solution with the best medicinal properties under controlled temperature conditions, and make it fully integrated into the toothpaste, which not only improves the utilization rate of medicinal materials and increases their added value, but also has a good effect on oral ulcers, periodontitis, and gums. Oral diseases such as bleeding are better than general drug toothpaste, which is more conducive to dental health.

The invention discloses new application of glutathione, particularly application of glutathione respectively in preparation of beta-lactam-antibiotic-containing antibacterial or bactericidal drugs, preparation of antibacterial or bactericidal drugs capable of enhancing pathogenic bacteria removal capacity of beta-lactam antibiotics, and preparation of antibacterial or bactericidal drugs capable of lowering drug resistance of bacteria to beta-lactam antibiotics. The glutathione can obviously enhance the sensitivity of bacteria to beta-lactam antibiotics; and the combination of the glutathione and beta-lactam antibiotics has better antibacterial effects than the single use of the beta-lactam antibiotics under the condition of the same dose.

The present invention provides a preparation method for an Escherichia coli inhibitor, and is characterized in that edible phenolic perfumes are used. The preparation method comprises steps that: adopting filter paper method to identify the bacteriostatic activity against Escherichia coli of 23 phenolic perfumes which have been approved to use in China, determining the minimum inhibitory concentrations of the perfumes by using double dilution method, and screening out 7 edible phenolic perfumes with good inhibitory effects against Escherichia coli; investigating effects of temperature, ultraviolet radiation and pH value on the bacteriostatic stability of the 7 perfumes, and further screening out 4 perfumes with good bacteriostatic stability; and through compounding the 4 perfumes, finding that when the mass ratio of 2-isopropylphenol, 4-propylphenol, 2-ethylphenol and 2-propylphenol is 1: 4: 2: 1, the inhibitory effect on Escherichia coli is best, and the minimum inhibitory concentration is 0.098 mg / mL.

The invention discloses a pharmaceutical composition for treating bacterial dairy cow mastitis. The pharmaceutical composition is prepared from the following raw materials: N-acetylcysteine, ampicillin, polyethylene glycol 400 and polyethylene glycol 4000; the invention further provides a preparation method of the pharmaceutical composition. The pharmaceutical composition has the beneficial effects that a preparation process is simple; the pharmaceutical composition is convenient to use in clinic; after the N-acetylcysteine and the ampicillin are compounded, the minimal inhibitory concentration of the ampicillin for main pathogenic bacteria, including escherichia coli, staphylococcus aureus, streptococcus agalactiae and streptococcus dysgalactiae, of the dairy cow mastitis can be remarkably reduced when being compared with that of single utilization of the ampicillin, so that the bacterium inhibition or bacterium killing effect of the ampicillin on the pathogenic bacteria is enhanced, and the pharmaceutical composition has a remarkable treatment effect on the dairy cow mastitis caused by the pathogenic bacteria; the pharmaceutical composition adopts a paste preparation and is injected into mammary chambers of dairy cows with the mastitis through a teat canal, so that the pathogenic bacteria can be rapidly killed; meanwhile, the pathogenic bacteria in the environment can be prevented from entering the mammary chambers and a prevention effect is realized; the pharmaceutical composition is easily absorbed and breast tissues of the dairy cows with the mastitis are not injured.
