Neglschisandrins 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 کاملSchizandrol A: a lignan from Schisandra chinensis
THE TITLE COMPOUND (SYSTEMATIC NAME 1,2,3,10,11,12-hexa-meth-oxy-6,7-dimethyl-5,6,7,8-tetra-hydro-dibenzo[a,c]cyclo-oc-ten-6-ol), C(24)H(32)O(7), has a dibenzocyclo-octa-diene skeleton. There are three mol-ecules in the asymmetric unit, which are related by a pseudo-translation in the direction of the c axis. Nevertheless, the three mol-ecules differ in the torsion angle of one of the meth-oxy ...
متن کاملChemical constituents from the leaves and stems of Schisandra lancifolia.
A new nortriterpenoid, 20-hydroxymicrandilactone D (1) and a novel lignan glycoside, lancilignanside A (2) were isolated from leaves and stems of Schisandra lancifolia, together with three known nortriterpenoids (3-5) and nine known phenolics (6-14). The structures of new compounds 1 and 2 were determined by detailed analysis of their 1D and 2D NMR spectra, and chemical evidences. In addition, ...
متن کاملNew Dibenzocyclooctadiene Lignans from Schisandra sphenanthera and Their Pro-inflammatory Cytokine Inhibitory Activities
Investigation of the fruits of Schisandra sphenanthera led to the isolation of two new dibenzocyclooctadiene lignans, methylgomisin O (1) and chloromethyl schisantherin B (2), together with twelve known lignans (3 – 14). Their structures were elucidated by using extensive spectroscopic techniques including 1D and 2D NMR spectra. Compound 2 was identified as a cyclooctadiene moiety substituted w...
