Further example details can be found in… A LC-MS approach is presented for the isolation of minor key plant biomarkers, in view of their characterization by NMR at the microgram scale …using ultra-performance liquid chromatography- time-of-ﬂight mass spectrometry (UPLC-TOF-MS) … then transferred to semi-preparative LC conditions with MS detection … and subsequent characterization by capillary NMR (CapNMR).
Hot Off the Press: Natural Products Workflow Herein we present a method of extract evaluation using HPLC proﬁling with biological evaluation 16 followed by capillary probe NMR spectroscopy/ESMS/UV combined with NMR database (AntiMarin) evaluation, which reduces the crude extract requirement for dereplication to submilligram quantities. 17
