An Aryldihydronaphthalene Lignan with a Novel Type of Ring System and Further New Lignans from Linum perenne L. [PDF]

open access: closedPlanta Medica, 2007
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.

A new species of Linum perenne group (Linaceae) from Calabria (S Italy)

open access: closedPlant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2011
Abstract A new heterostylous species, Linum katiae, is described from Calabria (southern Italy). This species differs from the closely related Linum alpinum − occurring in Alps and Apennines − by leaf width (3.1 ± 0.5 mm vs. 1.6 ± 0.4 mm), different flower color (bluish-white vs. blue), petals' size (25.8 ± 1.3 mm vs.

Origin of the Flax Cultivar ‘Appar’ and Its Position within the Linum perenne Complex

open access: closedInternational Journal of Plant Sciences, 2008
The ‘Appar’ flax germplasm was originally released by the USDA Soil Conservation Service as a cultivar of Linum lewisii. The observation that ‘Appar’ is heterostylic, a key taxonomic character distinguishing Lewis flax from other members of the Linum perenne complex, created a need for further study in order to resolve the taxonomic position of both ...

Arylnaphthalene and aryltetralin‐type lignans in hairy root cultures of Linum perenne, and the stereochemistry of 6‐methoxypodophyllotoxin and one diastereoisomer by HPLC‐MS and NMR spectroscopy

open access: closedPhytochemical Analysis, 2015
AbstractIntroductionHairy 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.ObjectiveTo elucidate the presence of aryltetralin‐type lignan diastereoisomers, besides the known arylnaphthalene‐type lignans, in ...

Justicidin B 7-hydroxylase, a cytochrome P450 monooxygenase from cell cultures of Linum perenne Himmelszelt involved in the biosynthesis of diphyllin

open access: closedPhytochemistry, 2007
Cell suspension cultures of Linum perenne L. Himmelszelt accumulate justicidin B as the main component together with glycosides of 7-hydroxyjusticidin B (diphyllin). A hypothetical biosynthetic pathway for these compounds is suggested. Justicidin B 7-hydroxylase (JusB7H) catalyzes the last step in the biosynthesis of diphyllin by introducing a hydroxyl

Life History Variation in Blue Flax (Linum perenne: Linaceae): Seed Germination Phenology

open access: closed, 1994
Linum perenne L. is a nonclonal perennial herb widely distributed across a range of habitats. Variation in seed germination patterns was examined for 21 Intermountain collections and for the commercial cultivar 'Appar'.
