Abstract: The effects of extraction temperature, extraction pressure, extraction time and the dosage of modifier on the extraction of nagringenin from peach leaf by supercritical CO2extraction technology have been studied in this article. By the experiment, the optimization conditions have been confirmed as: extraction temperature 60℃, extraction pressure 30MPa, extraction time 6h and the ratio of peach leaf mass and ethanol mass 1:2.0 (the modifier is 95% ethanol).

Key words: supercritical CO2, peach leaf, nagringenin
