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.
