Abstract: 【Objective】To investigate and optimize manipulation parameters of extraction technology of the chlorgenic acid in Herba Artemisia Scoparira by alcohol;【Method】Taking herba artemisira scoparira as the raw material, the single factor tests,orthogonal experimental designs and variance analyses were applied to optimize manipulation parameters of alcohol extraction technology;【Results】The results showed that alcohol possessed the strongest effect to chlorgenic acid among different solvents, the optimum manipulation parameters were as follows: 1.5h extraction in 60℃ 60% alcohol , and herba artemisira scoparira and 60% alcohol r proportion 1:15(g/ml);【Conclusion】It’s a good method to extract chlorgenic acid from Herba Artemisia Scoparira by 60% alcohol.
