| Abstract: | Objective The extraction technology of chlorogenic acid from Eucommia ulmoides leaf was studied with Ethanol as solvent. Methods Main factors influencing the extraction of chlorogenic acid from the leaves of Eucommia ulmoides were studied by single factor experiments, and then the optimized conditions for the extraction of chlorogenic acid were studied by orthogonal test.Results Optimized conditions were obtained as follows: Ethanol concentration 60%;extraction temperature 60℃; extraction time 2.5h; material to solvent 1:12. Conclusion The extraction ratio of chlorogenic acid was 2.434% in the optimized conditions. |
