Three new phenylpropanoid glycosides, named 1-O-[3-O-acetyl-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranosyl]-3-hydroxycinnamaldehyde (1), 1-O-[2,3-O-diacetyl-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranosyl]-3-methoxycinnamaldehyde (2), and 1-O-[3-O-acetyl-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranosyl]-4-allyl-2-methoxyphenol (3), were isolated from the 95% EtOH extract of the dry fronds of Conyza japonica. The structures of the new compounds were elucidated by spectral methods.
