| Abstract: | This paper studied the technology of extracting saponin from seeds of camellia oleifera with SFE-CO 2 technology.The optimal extracting conditions were as follows: pressure being 25 MPa,temperature of 50℃,65% ethanol being used as entrainer, time of 3h and flow rate of CO 2 being set at 25～30*#L/h.The yield was 15.23% .The content of camellia saponin extracted by SFE-CO 2 was 78.65% at the conditions listed above, 54%higher than that extracted by ethanol. |
| Keywords: | supercritical-CO 2 extraction camellia oleifera saponin |
