Abstract:

A new chalcone glycoside, butein-4-methoxyl-4'-O-(6''-O-acetyl)-β-D-glucopyranoside(2), along with seven known compounds, namely, quercitrin(1), luteolin-7-O-β-D-glucopyranoside(3), butein-4'-O-β-D-glucopyranoside(4), butein-4-methoxyl-4'-O-β-D-glucopyranoside(5), butin-7-O-β-D-glucopyranoside(6), isoquercitrin(7), and sulfurein(8) was isolated from aerial parts of Bidens ceruna L. Their structures were elucidated on the basis of spectroscopic studies. Compounds 1―8 were tested for their DPPH radical scavenging activity and, except compounds 2 and 5, other compounds showed scavenging activity.

Key words: Bidens ceruna L.; Constituent; Flavonoid; DPPH radical; Scavenging activity
