Venkateswarlu, Somepalli,Panchagnula, Gopala K.,Subbaraju, Gottumukkala V.

, p. 2183 - 2185 (2007/10/03)

3′,4′,6,7-Tetrahydroxyaurone (1a), an aurone isolated from Bidens frondosa, and five analogues (1b-1f) were synthesized from pyrogallol in three steps. The antioxidative activity of 1a-1f was determined by the superoxide free radical and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging methods.
