Objective To study the optimal supercritical-fluid extraction technique from total xanthones Swertia davidi Franch. Methods The uniform design method was used in experience arrangement. The yield rate of total xanthones was as indicator.Results The optimal extraction conditions were as follows:temperature at 50℃, pressure at 35 MPa,velocity of flow 4.5 ml·min~(-1),100% ethanol(volume fraction) as entrainer. The extraction rate was as high as 0.425%.Conclusion This technique is easy, convenient and workable, and can provide theoretical support for production.
