Abstract:
Objective To analyze the antioxidant activities of extracts from Scutellaria baicalensis Georgi. by different solvents, and to determine the contents of total flavonoids. Methods By employing colorimetric method, contents of total flavonoids in different extracts were determined. The free radical scavenging activity of each extract was measured by DPPH method. Results Different extracts from Scutellaria baicalensis Georgi. by different solvents were provided with DPPH free radical scavenging activities, of which the ethyl alcohol extracts were the highest in scavenging activities. In addition, total flavonoids content of ethyl alcohol extracts was significantly higher than that of others. Conclusion The antioxidant activity of extracts from Scutellaria baicalensis Georgi. was related to the content of total flavonoids in it.
