linum perenne/lignan

From the dichloromethane extract of aerial parts of Linum perenne L. (Linaceae), in addition to three lignans of the arylnaphthalene type (justicidin B, isojusticidin B and retrohelioxanthin), we isolated four lignans of the aryldihydronaphthalene type. The major constituent contains a novel type of

BACKGROUND Hairy root cultures of Linum sp. are an alternative for the high production of lignans. Linum perenne is known to produce arylnaphthalene-type lignans such as justicidin B, isojusticidin and diphyllin. OBJECTIVE To elucidate the presence of aryltetralin-type lignan diastereoisomers,

A cDNA encoding a pinoresinol-lariciresinol reductase PLR (PLR-Lp1) was isolated from a cell culture of Linum perenne Himmelszelt accumulating the arylnaphthalene lignan justicidin B. The recombinant PLR-Lp1 prefers (+)-pinoresinol in the first reaction step, but (-)-lariciresinol in the second

Mature seeds of 20 Linum species were analyzed for their content of lignans. The seeds of common flax (Linum usitatissimum L.) are known to contain as characteristic lignan sesoisolariciresinol diglucoside (SDG), whose presence in seeds of some other Linum species has also been reported. In order to
