| titleOfInvention | A method of preparing flavone extract in Armstrong |
| abstract | The invention discloses a kind of methods for preparing flavone extract in Armstrong, and steps are as follows：It by Armstrong pulverizing medicinal materials, is extracted 2-4 times, each 40-50min, power 650-750W with the EtOH Sonicate that volume fraction is 60-70%, Extracting temperature is 45-55 DEG C, and combined extract, extracting solution is concentrated under reduced pressure to give medicinal extract；Large pore resin absorption column chromatographic isolation is used after medicinal extract is dissolved with suitable quantity of water, successively with pure water, the ethanol gradient elution of volume fraction 10%, 30%, 50%, 70%, 95%, is collected 70% alcohol elution, then separate through silica gel column chromatography, is successively used volume ratio 32:1,26:1,11:1,3:1 chloroform-methanol elution, collects 11:1 elution fraction, is concentrated to obtain the final product.This method Extracting temperature is low, the time is short, and extraction efficiency is high, can effectively obtain flavones ingredient in Armstrong, has bright prospects. |
