Icariin extract

Icariin extract is a product processed from the dried stems and leaves of Epimediumbrevicornum, etc. The commercial extract has many specifications, and usually takes icariin or total flavones as the standardized index. There are about 30 species of Icariin in Berberis Chemicalbook family in the world, and 20 species in China. Except Korean Epimedium which is distributed in north Korea, the others are endemic in China. Chinese epimedium origin is more, mainly produced in Shaanxi, Shanxi, Gansu, Anhui, Hunan, Hubei and other places.

Analytical method

1. By thin-layer identification method, 0.5g of herb powder or an appropriate amount of extract of Herba fuli was taken, 10ml of ethanol was added, soaked in warm water for 30 minutes, filtered, the filtrate dried, and the residue was dissolved with 1ml of ethanol to form the test solution. Weigh the icariin control product, dissolve it with methanol and dilute it into 0.1mg/ml, that is, the control product solution. The test solution and the control solution were absorbed 10μl each on the silica gel H thin layer plate with the same sodium carboxymethyl cellulose as binder, and the solution was divided into ethyl acetate, butyl ketone, formic acid and water (10:1:1: 1) For the developing agent, unfold, remove, dry, put ultraviolet lamp (365nm) to examine, the test product chromatogram, and the control product chromatogram in the corresponding position of the same dark red spots; Spray aluminum trichloride solution, and then ultraviolet lamp (365nm) to examine, the same orange-red fluorescence spots. 2. The content of total flavonoids in Epimedium and its extract was determined by spectrophotometry. The control product icariin was accurately weighed and prepared into a standard solution of 10ug/ml with methanol. Accurately weigh the appropriate amount of this product powder (equivalent to about 1mg containing icariin), use 25ml methanol ultrasonic chemical book for 30 minutes, fixed volume in 50ml measuring bottle, with 0.45μm microporous filter membrane filtration, that is, the test product solution. Take the test solution and the control solution, take the reagent as blank, and measure the absorption at 270nm wavelength. 3. Determination of icariin in Epimedium and its extracts by HPLC chromatographic conditions and systematic applicability test: ODS25uC18(4mm×150mm) column; Mobile phase: acetonitrile-water (30:70); Detection wavelength: 270nm; Flow rate: 0.8ml/min. The theoretical plate number is not less than 1500 icariin. Preparation of reference solution: The reference product icariin was precisely weighed and prepared into 0.1mg/ml solution with methanol. Preparation of test product solution: Accurately weigh the appropriate amount of this product powder (equivalent to about 1mg containing icariin), ultrasonic with 25ml methanol for 30 minutes, fixed volume in 50ml measuring bottle, with 0.45μm microporous filter membrane filtration, that is, the test product solution. Determination method: The sample solution and the control solution were injected 10μl into the HPLC instrument respectively, and the area was calculated by external standard method.
