ABSTRACT
AIM:
To test the effect of ethanol precipitation on the purifying technology of chlorogenic acid (CGA).METHODS:
Using HPLC, the effect of the extraction of CGA from the crude Flos Lonicerae Japonica powder with three concentrations of ethanol was compared.RESULTS:
Ethanol with concentration of 60% was optimal. CGA content was raised from 5.5% to 37.72% by use of ethanol precipitation and extraction in combination.CONCLUSION:
The ethanol precipitation can get rid of the impurity in the crude powder of Flos Lonicerae Japonica effectively and the yield of CGA can reach 90.16%.
