Lignans from Torreya jackii identified by stopped-flow high-performance liquid chromatography-nuclear magnetic resonance spectroscopy
Journal of Chromatography A, 837(1999)83-91，-0001，（）：
Coupled reversed-phase HPLC-NMR spectroscopy has been applied to the rapid detection and identification of plant metabolites of Torreya jackii, a species of Taxaceae. Analysis consisted of gradient HPLC elution and directly coupled H NMR (500 MHz) spectroscopic detection in a stopped-flow mode. Seven lignans were detected and their structures were 1 elucidated, based on their HPLC-1 H NMR spectra and MS data. The structures were confirmed by isolation of the single components followed by conventional NMR measurements.
