| titleOfInvention | A kind of preparation method of Chemical Constituents of Flavones from Corn Silk |
| abstract | The invention discloses a kind of preparation methods of Chemical Constituents of Flavones from Corn Silk, steps are as follows: taking corn stigma medicinal material that 10 times of amount water is added to decoct 2-4 times, each 2-3h, collecting decoction, filtration, filtrate concentration, centrifugation, take supernatant, adjustment concentration is 0.8g medicinal material/mL, with AB-8 type macroporous resin purification, wet method dress post, upper prop concentration is 0.8g medicinal material/mL, loading speed is 2.5-3.5BV/h, standing adsorption 3-4h, first eluted with the hydrochloric acid solution of 5.5-6.5BV, pH is 2.4-2.6, the 55-65% ethanol elution of 5.5-6.5BV is used again, pH is 10.4-10.6, elution speed is 2.5-3.5BV/h, collect ethanol eluate, it is concentrated under reduced pressure to obtain the final product.This method is easy, quick, easy to operate, and the Maize silk flavones extract of preparation has preferable antigout arthritis effect, can be used for drug preparation. |
