STUDY ON TECHNIQUE OF EXTRACTION AND ISOLATION OF CHLOROGENIC ACID FROM LEAVES OF EUCOMMIA ULMOIDES

Jing Qian

Abstract

Main factors influencing the extraction of chlorogenic acid from the leaves of Eucommia ulmoides were studied by single factor and orthogonal experiments as well as multiple analysis.Optimized conditions for the extraction of chlorogenic acid were obtained:the whole leaves(unsmashed)were extracted by 40% ethanol at 80 ℃ for 2 h with a ratio (material to solvent) of 1∶16.
