| Abstract: | Objective ： To determine the optimal extraction technology of flavonoid from cherry leaves. Methods：Supercritical CO2 extraction was applied with absolute alcohol as entrainer. The influence of extraction pressure,temperature and time on extraction yield was investigated by orthogonal experimentation. Results：The optimal extraction conditions showed pressure 20MPa,temperature 45℃ and time 3h. Conclusion：Method of extraction of flavonoid from cherry leaves with supercritical CO2 is feasible. Product quality is good and extraction yield is relatively high. |
