The injection is a sterilized aqueous solution prepared by extracting glabrous sarcandra herb and is characterized in that every milliliter of the solution contains not less than 100 mu g of rosmarinic acid; every milliliter of the solution contains not less than 500 mu g of chlorogenic acid and cryptochlorogenic acid, wherein the ratio of the chlorogenic acid to the cryptochlorogenic acid is (2:1)-(5:4); and the pH value of the solution is 5.0-5.5. The injection is stable in quality.

The invention discloses a method for controlling corn armyworm by using nanometer silicon quantum dots, and belongs to the technical field of nanometer material prevention and control of crop pests. The method of using nano-silicon quantum dots in the present invention to prevent and control corn armyworm, the method is to prepare nano-silicon quantum dots as an aqueous solution of nano-silicon quantum dots, and then apply them to plant roots or leaves as plant fertilizers; wherein the The concentration of the aqueous solution of the nano-silicon quantum dots is 10-150mg / L; the size of the nano-silicon quantum dots is 3-8nm. The method of the present invention not only improves the effect of conventional silicon fertilizers on plant stress resistance, but also directly improves the direct insecticidal effect of nano-silicon and the improvement of the plant's own chemical defense ability; by spraying different concentrations of nano-silicon quantum dots The optimal spraying amount of nano-silicon quantum dots was established in the growth and development experiment of armyworm.

The invention relates to wild honeysuckle flower health protection teabags comprising the following raw materials in parts by weight: 10-20 parts of wild honeysuckle flower, 20-30 parts of wild honeysuckle flower leaves, 10-20 parts of wild honeysuckle flower twigs, 15-25 parts of liquorices, 10-20 parts of tea leaves and 10-20 parts of stevia rebaudianum. A making method of the wild honeysuckle flower health protection teabags comprises the following steps of: screening to remove impurities; washing by using water, and then airing or air-drying; respectively smashing, screening, collecting raw material granules within a range of 60-100 meshes for later use; sufficiently mixing and uniformly stirring according to the parts by weight; irradiating by using ultraviolet rays for disinfection and sterilization; loading into filter paper bags according to the specification of 2-5 grams per bag, and carrying out heat-sealing; respectively loading into packaging boxes, and then checking and warehousing. The wild honeysuckle flower health protection teabags have the beneficial effect of playing a role in enhancing immunity when people drink tea; in addition, the wild honeysuckle flower health protection teabags disclosed by the invention have the advantages of readily available raw material sources, lower cost and price, capability for large-scale production and suitability for ordinary people to drink and can generally increase the level of the physical health of people.

The invention discloses a probiotic feed with high viable bacteria count and a method prepared by fermenting liquor distiller's grains with Lactobacillus plantarum. The probiotic feed with high viable count is made of the following raw materials in parts by weight: dried distiller's grains 70-85 , Eucommia leaf powder 15-30, ammonium sulfate 0-3.0, fructo-oligosaccharide 0.5-2 and inulin 0.5-2. The preparation method is as follows: add Eucommia ulmoides leaf powder, ammonium sulfate, fructooligosaccharide and inulin to the dried distiller's grains, mix evenly, and steam the material with moist water; after steaming, inoculate Lactobacillus plantarum suspension for anaerobic solid-state fermentation to obtain High viable count probiotic feed. The invention utilizes the strong ability of Lactobacillus plantarum to decompose sugars, degrades the macromolecular sugars in distiller's grains and Eucommia leaves, and increases the content of crude protein, small peptides, oligosaccharides and monosaccharides in feed; and after Eucommia leaves are fermented, It also increases the content of chlorogenic acid in the feed, while adding prebiotics also increases the proliferation of Lactobacillus plantarum in the intestinal tract of animals.

The invention provides a method for extracting chlorogenic acid and caffeic acid from coffee beans. The whole set of method is put forward for extracting high-purity chlorogenic acid and caffeic acid from coffee beans by conducting degreasing, conducting pyruvic acid water extraction, making the mixture pass through large-hole adsorption resin, conducting concentration, conducting extraction through ethyl acetate, conducting decoloration through activated carbon, and conducting crystallization and recrystallization. The requirement of the whole separation process for environment conditions is not high, the separation time is short, and purity is the highest. Separation materials can be easily obtained and are cheap, the separation operation process is simple and easy to control, crystallization and recrystallization are adopted, the purification efficiency is high, and yield is high.

The invention discloses a method for increasing the content of chlorogenic acid in chrysanthemum inflorescences. The method comprises the following steps: (a) putting picked fresh chrysanthemum inflorescences into a culture room, and irradiating by using ultraviolet rays UV-B at irradiation intensity of 50-600muW / cm<2> for 15-120 minutes under the conditions that the temperature is 20-25 DEG C and the humidity is 50%-80%; (b) transferring the irradiated inflorescences into a culture box and performing dark culture for 12 hours under the conditions that the temperature is 20-25 DEG C and the humidity is 50%-80% in the box; (c) performing fixation on the inflorescences processed in the step (b) in a drying machine at 100-150 DEG C for 8-10 minutes, and drying at 50-55 DEG C until the weight is constant. According to the preparation method, the process is simple, the environment-friendly effect is achieved, the safety coefficient is high, the production cycle is short, the cost is low, the benefit is high, the operation controllability is good and the chlorogenic acid is suitable for large-scale industrialized production.
