Abstract:
... The phenolic constituents of the roots ofTaxus cuspidata (Japanese yew) were investigated. Four lignans, [(+)-taxiresinol (1), (+)-lariciresinol (2), (−)-secoisolariciresinol (3), and (+)-pinoresinol (4)] were isolated and identified. The assignment of proton and carbon atoms for the lignans were finally solved by one- and twodimensional-nuclear magnetic resonance spectra. The enantiomeric excess ...

Abstract:
... The plant lignans secoisolariciresinol and matairesinol occur in numerous foods such as oilseeds, whole grains, vegetables, and fruits. We have studied the hitherto unknown oxidative metabolism of secoisolariciresinol and matairesinol in hepatic microsomes from untreated and Aroclor 1254-induced Wistar rats and from humans. Five oxidative metabolites of secoisolariciresinol and 10 oxidative metabo ...

Abstract:
... HPLC-SPE-NMR has been applied to the analysis of a number of structurally similar lignans present in Phyllanthus urinaria. A reversed-phase HPLC system, using a C8 column eluted with tetrahydrofuran-water-methanol and detected at 225 nm was developed that gave good resolution for seven lignans from Phyllanthus urinaria. Coupling of this system with SPE-NMR provided clean 1H-NMR spectra for nine li ...
