Abstract

Abstract:

The total flavonoids of Emilia sonchifolia were extracted by ethanol refluxing and separated by polyurethane column, and their scavenging activities to 1,1-diphenyl-2-picrylhydrazyl (DPPH·) and hydroxyl radicals were measured by spectrophotometry. The results showed that the obtained products from Emilia sonchifolia are total flavonoids confirmed by thin layer chromatography, the separation effect of total flavonoids from Emilia sonchifolia is satisfying, and the total flavonoids present good scavenging activities to DPPH· and hydroxyl radicals with the IC50 values of 4.8×10-3 mg/ml and 0.53 mg/ml, respectively.

Key words: Emilia sonchifolia, total flavonoids, DPPH radical, hydroxyl radical, anti-oxidant action
