Abstract

The invention relates to a Stellera chamaejasme L extract and an anti-tumor action thereof. The Stellera chamaejasme L extract of the invention is extracted by absolute ethyl alcohol to obtain a primary extract; the primary extract is further treated by macroporous resin column chromatography or polyamide column chromatography and then eluted by water and ethyl alcohol to obtain a secondary extract; and in the secondary extract, the secondary extract separated by a macroporous resin column is further treated by polyamide column chromatography and then eluted by water and ethyl alcohol to obtain a tertiary extract.
