Lignans - Isolation & purification
Research News and Information
Definition of 'Lignans'A class of dibenzylbutane derivatives which occurs in higher plants and in fluids (bile, serum, urine, etc.) in man and other animals. These compounds, which have a potential anti-cancer role, can be synthesized in vitro by human fecal flora. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Common names: Lignans; Neolignans |

Nitric oxide scavenging lignans from Vitex negundo seeds.
30 Aug 2009 
A new phenyldihydronaphthalene-type lignan, vitexdoin A (1), a new phenylnaphthalene-type lignan alkaloid, vitedoamine B (2), four new phenylnaphthalene-type lignans, vitexdoins B-E (3-6), and four known lignan derivatives (7-10) were isolated from ... Read more...
Oxygenated lignans from the fruits of Schisandra arisanensis.
30 Aug 2009 An acetone extract of the fruits of the Taiwanese medicinal plant Schisandra arisanensis has yielded 11 new oxygenated lignans. Four of these, named arisantetralones A-D (1-4), possess the aryltetralone skeleton, while the other seven, named ... Read more...
Constituents of the leaves of Magnolia ovata.
30 Jul 2009 Two new lignans, magnovatins A (1) and B (2), along with nine known compounds, were isolated from the leaves of Magnolia ovata. The known compounds were identified as acuminatin (3), licarin A (4), kadsurenin M, 4-O-demethylkadsurenin M, oleiferin ... Read more...
