Taxane analysis by high performance liquid chromatography-Nuclear magnetic resonance spectroscopy ofTaxus species

1998

High performance liquid chromatography–nuclear magnetic resonance spectroscopic analyses of taxane diterpenoids from three Taxus species were carried out employing a stopped-flow technique. Several taxanes have been identified from 500 mg leaf samples without prior isolation. © 1998 John Wiley & Sons, Ltd.

Lignans from Torreya jackii identified by stopped-flow high-performance liquid chromatography–nuclear magnetic resonance spectroscopy

1999

Abstract 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 1 H NMR (500 MHz) spectroscopic detection in a stopped-flow mode. Seven lignans were detected and their structures were 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.
