For the utilization of the resources of Dracocephalum rupestre Hance, the content of total phenol and total flavonoids in different polar extracts was determined. The results showed that the content of total phenol and total flavonoids in ethyl acetate fraction was 74.5 mg/g and 426.70 mg/g, respectively, much higher than other fractions. Six compounds, eriodictyol, komaroviquinone, pedalitin, dracocequinone A, gardenin B and cirsimaritin were identified from the samples by LC-MS. In vitro antioxidant analysis showed that the D. rupestre Hance had strong antioxidant activity.
