Applications of Supercrifical Fluid Exiraction Technique in Alkaloids Extraction

Supereritical fluid extraction technique which possesses the advantage of good selectivity,high yield,simple technology,temperate operation state,environmental protection and so on,has be used in the extraction and separation of Chinese herbal medicine extensively.The current applications and traits of supercritical fluid extraction technique in alkaloids' extraction were reviewed emphatically in this paper according to the classification of alkaloids' pharmacological action.Furthermore,the tendency,prospect and problem eximed presently of SFE technique were also expected and discussed.The result showed it could efficiently extract alkaloids from the plants and the combination of it and other separate methods would be the developmental direction of natural alkaloids'extraction and separation in future.
