Abstract: Taking Acer truncatum Bunge leaves as the raw material, the best enzyme was screened from different enzymes for extracting the chlorgenic acid. The single factor tests, orthogonal experimental designs and variance analyses were applied to optimize manipulation parameters of enzymes in the extracting technology. The results showed that the cellulase possessed the optimum effect to extract chlorgenic acid among the other enzymes. The optimum manipulation parameters are: cellulase dosage 0.015%, pH value 4.5, 50℃ and extraction time 2.2h.

Key words: Acer truncatum Bunge, chlorgenic acid, cellulase, extraction
