Two new lignans from Schisandra henryi.
Two new lignans, henricines A (1) and B (2), were isolated along with the eight known lignans, ganshisandrine (3), wulignan A(2) (4), epiwulignan A(1) (5), deoxyschisandrin (6), wulignan A(1) (7), epischisandrone (8), schisantherin A (9), and schisandrol A (10), from the stems of Schisandra henryi. The structures of the new compounds were elucidated based on the spectral analysis, including 1D ...
متن کاملNeglschisandrins C-D: two new dibenzocyclooctadiene lignans from Schisandra neglecta.
Two new dibenzocyclooctadiene lignans, neglschisandrins C-D (1-2), were isolated from the stems of Schisandra neglecta. Their structures and stereochemistries were elucidated by spectroscopic methods, including 1D- and 2D-NMR and HR-ESI-MS techniques.

متن کاملNeglschisandrins E-F: two new lignans and related cytotoxic lignans from Schisandra neglecta.
Phytochemical investigation of an ethanolic extract of stems of Schisandra neglecta led to the isolation and identification of two new dibenzocyclooctadiene lignans, designated neglschisandrins E (1) and F (2), and thirteen known lignans. All structures and stereochemistries were determined by spectroscopic methods, including 2D-NMR techniques. The isolates were evaluated for in vitro cytotoxic...
متن کاملNew Thymoquinol Glycosides and Neuroprotective Dibenzocyclooctane Lignans from the Rattan Stems of Schisandra chinensis.
Three new lignans (1 - 3), together with four new thymoquinol glycosides (4 - 7), were isolated from 70%-EtOH extract of the rattan stems of Schisandra chinensis. The structures of 1 - 7 were elucidated by detailed spectroscopic analyses, and these new compounds were identified as pinobatol-9-O-β-d-glucopyranoside (1), 1,2,13,14-tetramethoxydibenzocyclooctadiene 3,12-O-β-d-diglucopyranoside (2)...
