Efficient extraction and separation method for chemical components in peanut shells

The invention discloses an efficient extraction and separation method of chemical components in peanut shells, which comprises the following steps: crushing raw peanut shells, weighing powder, adding 95% ethanol to soak for 3 hours, carrying out heating reflux extraction for 3 times, carrying out reflux extraction for 40 minutes each time, filtering an extracting solution, carrying out vacuum concentration, steaming until no alcohol smell exists, extracting twice with the same amount of petroleum ether, discarding a petroleum ether phase, then extracting for 3 times with the same amount of ethyl acetate, and carrying out vacuum concentration to obtain the chemical components in the peanut shells. The method is characterized in that a high-speed counter-current chromatography head-tail elution mode is adopted, and a solvent is used for separating the crude extract of the raw peanut shells. According to the method, the crude peanut shell extract can be effectively separated. 本发明公开了一种花生壳中化学成分的高效提取和分离方法，将生花生壳粉碎，称
