Embodiment 1
[0071] Embodiment 1: the extraction example of pharmaceutical composition in the present invention
[0072] Epimedium and Fructus Cnidii are properly crushed, mixed thoroughly at a ratio of 2:1, a total of 1000g, extracted twice with 70% ethanol (10 times the amount, 1.5h; 8 times the amount, 1h); , concentrated under reduced pressure, and then centrifuged to remove the precipitate; after the solvent was recovered under reduced pressure, an appropriate amount of water was added, and the sample was suspended by ultrasonic treatment. On the sample liquid (pretreatment has been completed) macroporous adsorption resin AB-8, the amount of resin is 500g, the impurities that are not adsorbed are washed with water, and then eluted with 70% ethanol; the collected liquid is concentrated, spray-dried to obtain the 34.29g of dry powder with total flavonoids of Husk and total coumarin of Cnidium as the main active ingredients, the yield is 3.43%.
Embodiment 2
[0073] Embodiment 2: Determination of content of icariin, total flavonoids of Epimedium, osthole, total coumarin of Cnidium
[0074] 2.1. Both icariin and osthole were purchased from China National Institute for the Control of Pharmaceutical and Biological Products, and both were used as reference substances for purification research and content determination.
[0075] 2.2. The content of icariin, total flavonoids of Epimedium, and osthole were determined according to the provisions of the content determination item of Chinese medicinal materials in the Pharmacopoeia of the People's Republic of China in 2000, respectively, using high-performance liquid chromatography, ultraviolet-visible Spectrophotometry, thin-layer scanning chromatography. In Example 1, icariin is 18.42%, total flavonoids of Epimedium is 41.1%, and osthole is 7.3%.
[0076] 2.3. Determination of the total coumarin content of Cnidium Fructus refers to the literature [Zhang Xinyong, Xiang Rende, Zhang Genyuan...
Embodiment 3
[0077] Embodiment 3: the influence of the present invention on guinea pig allergic asthma
[0078]3.1 Materials and methods
[0079] 3.1.1 Animal grouping: 60 hartley guinea pigs, weighing 230±20g, were randomly divided into A model control group, B dexamethasone group, and C epimedium total flavonoids (provided by the Analytical Chemistry Laboratory of Chinese Medicine, Shanghai University of Traditional Chinese Medicine, content 62.1%) , yield is 2.35%.) group, D Cnidium total coumarin (provided by Shanghai University of Traditional Chinese Medicine Analytical Chemistry Office of Chinese Medicine, content 57.4%, yield is 1.84%.) group, E Epimedium, snakehead of the present invention Fructus Cnidii composition (provided by the Laboratory of Analytical Chemistry of Chinese Medicine, Shanghai University of Traditional Chinese Medicine, the ratio of Epimedium and Fructus Cnidii is 2:1, decocted in 10 times the amount of water, 1 hour each time, twice in total, and the filtrate i...
