Isolation and structure elucidation of ligustroflavone, a new apigenin triglycoside from the leaves of Ligustrum vulgare L.
A new flavone, apigenin-7-O-beta-(2",6"-di-alpha-rhamnopyranosyl)-glucopyranoside , named ligustroflavone, was isolated from the leaves of common privet (Ligustrum vulgare L., Oleaceae), whose popular use was well known in the Mediterranean historical medicine and ethnomedicine as anti-inflammatory. The structures of other five apigenin and luteolin derivates, isolated from the polar fractions of the methanolic leaf extracts, were elucidated.
