摘要
The DPPH radical scavenging activity of two flavonol glycosides obtained from ethanolic extracts of Aconitum napellus sp. lusitanicurn was studied. The results showed a high DPPH antiradical activity of compound 1 (quercetin 3-O-(6-transcaffeoyl)-beta-glucopyranosyl-(1 -> 2)-beta-glucopyranosyl-7-O-alpha-rhamnopyranoside) when compared with compound 2 (quercetin-3-sophoroside-7-rhamnopyranoside), rutin and ascorbic acid. The relationship between the caffeoyl and rhamnopyranoside groups in the flavonol glycosides structures and the DPPH antiradical activity was also discussed. (c) 2006 Elsevier B.V.
