Hyphenated NMR methods in natural products research, part 1: Direct hyphenation
Open accessAbstract
This review describes the current status of the development of techniques combining liquid chromatography and nuclear magnetic resonance and their use in the context of natural products. HPLC-NMR methods have a rapidly growing impact on natural products research by enabling structure determination of natural products directly from small amounts of extracts, i. e., prior to the investment in an often lengthy and laborious preparative-scale isolation process. This speeds up extract dereplication and helps to avoid re-isolation of already known extract constituents. Direct HPLC-NMR hyphenation techniques, defined as methods in which NMR spectra are recorded using the HPLC eluate, are described. The recently developed indirect HPLC-NMR method employing an automated solid-phase extraction interface between HPLC and NMR, which replaces the chromatographic solvent with a different solvent for NMR data acquisition, is described in the second part of this review.

Hyphenated techniques have considerable potential in the dereplication of biological samples.
“Although complicated and expensive to establish, hyphenated techniques have considerable potential in the dereplication of biological samples, i.e., samples can be quite rapidly screened to determine if they contain only already-known analogues or to differentiate the unknown analogues from the known ones so that time and research effort are not wasted in rediscovering compounds [143].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
