Abstract: The best condition for extract flavones in holly leaf was determined by orthogonal test. The UV spectrophotometer was used to determine the content of flavones of extraction, DPPH assay method was used to determine the antioxidant activities of extraction. The best condition for extracting flavones in holly leaf was: extraction 18h with 70% concentration of ethanol, and reflux 4h in total, extraction production rate was 1.13%, the best antioxidant properties was 97.74%, and the content of flavones was directly proportional to the antioxidant activities.

Key words: holly, flavones, extract, activity determination
