| titleOfInvention | Method for extracting and purifying chlorogenic acid from smilax or congeneric plants thereof |
| abstract | The invention discloses a method for extracting and purifying chlorogenic acid from the roots or leaves of smilax or congeneric plants thereof. The method comprises the following steps: grinding the roots, stalks or leaves of the smilax or the congeneric plants thereof; performing sieving through a 2# sieve; performing ultrasonic or reflux extraction through water or low-concentration ethanol, performing filtration, and recovering a solvent until alcohol smell disappears; performing filtration, and loading a filtered solution to polystyrene type macroporous adsorption resin; performing gradient elution; extracting eluate through ethyl acetate, recovering ethyl acetate, and separating out a chlorogenic acid crystal; re-crystallizing 50 percent of ethanol water solution for 3-4 times. The purity of chlorogenic acid obtained through the method can be greater than 98.0 percent. According to the method, the smilax is used as a raw material for extracting chlorogenic acid for the first time, so that medicinal components of the smilax are fully utilized; the method is simple in process, short in production period and high in product purity, and has a broad application value and good social and economic benefits. |
