A new seco-neolignan glycoside from the root bark of Ailanthus altissima.[Pubmed: 21916771 ]

METHODS AND RESULTS:
A new seco-neolignan glycoside, seco-dehydrodiconiferyl alcohol-4-O-β-D-glucopyranoside, together with eight known compounds, were obtained from the EtOH extract of the root bark of Ailanthus altissima. Their structures were elucidated based on the spectroscopic data.
CONCLUSIONS:
Three neolignan glycosides including 7,9,9'-trihydroxy-3,3',5'-trimethoxy-8-O-4'-neolignan-4-O-β-D-glucopyranoside, sonchifolignan B and Citrusin B exhibited moderate in vitro inhibitory effect on tobacco mosaic virus replication with IC₅₀ values 0.30, 0.35 and 0.26 mmol L⁻¹, respectively.

A new lignan from stems of Sargentodoxa cuneata.[Pubmed: 24079238]

Sargentodoxae Caulis was prepared from the stems of Sargentodoxa cuneata.
METHODS AND RESULTS:
Twenty compounds from the the stems of S. cuneata collected in Huangshan Mountain, Anhui province, were isolated and purified by column chromatography on macroporous resin (HPD100), silica gel, Sephadex LH-20 and semi-preparative HPLC. Their structures were elucidated on the basis of physico-chemical properties and spectral data analyses as (7R,8S)-3,3 '-5-trimethoxy-4,9-dihydroxy-4',7-expoxy-5',8-lignan-7'-en-9'-oic acid 4-O-beta-D-glucopyranoside(1), 1-O-(vanillic acid) -6-O-vanilloyl-beta-D-glucopyranoside(2), 4-hydroxyphenylethyl-6-O-coumaroyl-beta-D-glucopyranoside(3), Citrusin B(4), cinnamoside(5), (-) -isolariciresinol 4'-O-beta-D-glucopyranoside (6), (-) -isolariciresinol 4-O-beta-D-glucopyranoside (7), 1-O-(vanillic acid) -6-(3", 5"-dimethoxy-galloyl) -beta-D-glucopyranoside (8), 4-hydroxyphenyl-ethyl-6-O-(E) -caffeoyl-beta-D-glucopyranoside (9), (-)-syringaresinol 4'-O-beta-D-glucopyranoside (10), (-)-syringaresinol di-O-beta-D-glucopyranoside (11), aegineoside (12), calceolarioside B (13), 4-hydroxy-3-methoxy-acetophenone-4-O-alpha-L-rhamnopyranosyl-(1 --> 6)-beta-D-glucopyranoside (14), 4-hydroxy-3-methoxy-acetophenone-4-O-beta-D-apiofuranosyl-(1 --> 6) -beta-D-glucopyranoside (15), (-) -epicatechin (16), salidroside (17), 3,4-dihydroxy-phenyl ethyl-beta-D-glucopyranoside (18), chlorogenic acid (19) and protocatechuic acid (20).
CONCLUSIONS:
Compound 1 was a new compound and compounds 2-7 were isolated from this plant for the first time.
