Compared with a traditional method, the technology has good precision and reproducibility, the data result is accurate and reliable, meanwhile, the technology can identify the 13 components at the same time under the same chromatographic condition, the analysis efficiency is remarkably improved, synchronous monitoring of multiple effective components is achieved, and the consistency and stability of the preparation quality can be guaranteed.

The invention belongs to the technical field of detection, and discloses a method for detecting the content of five components in a traditional Chinese medicine preparation child heat-clearing and lung-benefiting oral liquid. According to the method, the contents of five active ingredients, namely ephedrine hydrochloride, pseudoephedrine hydrochloride, tectoridin, forsythin and arctiin, in the oral liquid for clearing heat and benefiting lung for children are simultaneously detected by adopting a multi-wavelength switching method through a specific solvent and chromatographic conditions. Compared with the prior art, the method has the advantages that the problems of single component, long detection period, high labor and reagent cost and the like in content determination of the oral liquid for clearing heat and benefiting lung for children are solved, the method is simple, convenient, high in specificity, good in repeatability and accurate in result, and reference can be provided for process research, quality guarantee and quality standard improvement of the oral liquid for clearing heat and benefiting lung for children.

This invention belongs to the field of novel pharmaceutical uses, and more specifically, relates to the application of arctiin in the preparation of drugs for treating porcine reproductive and respiratory syndrome (PRRS). This invention is the first to discover that arctiin has a significant antiviral effect against PRRSV, and demonstrates through Western blotting and qRT-PCR techniques at multiple levels that arctiin can significantly inhibit PRRSV infection and replication, exhibiting significant anti-PRRSV activity. It can be used to prepare drugs for treating PRRSV, and also for preparing drugs to treat PRRSV infection.

The hermetia illucens insect sand organic fertilizer is prepared from the following components in parts by weight: 90 to 110 parts of hermetia illucens insect sand, 11 to 15 parts of corn straw powder, 8 to 12 parts of sawdust and 2 to 2.5 parts of bioactive substances, the bioactive substances comprise arctiin and magnolol; the mass ratio of arctiin to magnolol is (1-9): 9. According to the organic fertilizer and the preparation method thereof, the double breakthrough of efficient recycling of the kitchen garbage and high-value utilization of the organic fertilizer is achieved, the organic fertilizer provided by the invention can remarkably promote plant growth and prevent and treat clubroot of plants, the problems of chemical pesticide residues and drug resistance of pathogenic bacteria can be avoided, and an effective solution is provided for recycling of the kitchen garbage and development of green agriculture.

The invention discloses a method for synchronously and quantitatively detecting 14 components in fructus forsythiae based on ultra-high performance liquid chromatography, and belongs to the technical field of quality detection of traditional Chinese medicinal materials. Dissolving the fructus forsythiae powder in a methanol aqueous solution, and extracting to obtain a to-be-detected sample; the method comprises the following steps: respectively preparing a standard solution and a mixed standard solution by taking chlorogenic acid, forsythiaside I, forsythiaside B, rutin, forsythiaside A, forsythiaside H, tectoridin, pinoresinol-beta-D-glucoside, naringin, forsythin, arctiin, quercetin, kaempferol and forsythiaside as standard substances; the method comprises the following steps: acquiring a standard curve corresponding to each standard substance, a peak position and a chromatographic result of a to-be-detected sample solution through ultra-high performance liquid chromatography, and substituting the chromatographic result into a standard curve equation of the standard substance; and calculating the contents of chlorogenic acid, forsythiaside I, forsythiaside B, rutin, forsythiaside A, forsythiaside H, tectoridin, pinoresinol-beta-D-glucoside, naringin, forsythin, arctiin, quercetin, kaempferol and forsythiaside in the sample to be detected.

This invention discloses a quality testing method for pediatric throat-clearing granules, belonging to the field of traditional Chinese medicine preparation quality control technology. The method optimizes the identification methods for indigo naturalis and burdock seed using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC), and adds identification methods for dandelion, scrophularia, and forsythia. Furthermore, HPLC is used to simultaneously determine the content of arctiin and forsythoside. This invention enables quality control of the five medicinal materials in pediatric throat-clearing granules, thus allowing for more effective and comprehensive control and evaluation of the quality of this traditional Chinese medicine preparation. Moreover, this method has advantages such as safety, durability, and good repeatability.
