Abstract
Objective:
To study the extxtraction process of chlorogenic acid from Yinju sugarless granules.
Methods:
The optimal extraction process was selected with orthogonal design. The content of chlorogenic acid in the extract was detremined.
Results:
The content of chlorogenic acid was influenced by frequency of extraction, the quantity of water and the concentration of ethanol.
Conclusions:
The optimal extraction process is extraction 3 times with 10 times water and with 70% ethanol.
