Comparatively sundried flowers are more suitable to be extracted as an industrial material although the concrete yield of fresh flowers is a little more. At the same time the experiment process fully proves the selectivity of SFE-CO2. Low temperature and low pressure are suitable to extract concrete from natural flavor and fragrance;(2) The materials prepared to extract rutin are the flowers that are gotten rid of concrete by SFE-CO2. The extraction methods include the SFE-CO2 modified by alcohol, the method of hot alkali-precipitate with acid, and alkaly dissolving and acid subsiding combined with microwave or ultrasonic.
