Covering the literature from mid-2004 until the end of 2011, this review continues a previous
literature overview on quantitative 1H NMR (qHNMR) methodology and its applications in …

1H and 13C NMR spectroscopy is routinely used for the elucidation of structures of newly
synthesized compounds, natural products and semi-synthesized compounds. The …

In the fields of medicine and health, traditional high-performance liquid chromatography or
UV-visible spectrophotometry is generally used for substance quantification. However, over …

Covering: marine indole alkaloids (n= 2048) and their reported bioactivities up to the end of

This study demonstrates how regio-and diastereo-isomers with near-identical NMR spectra
can be distinguished and unambiguously assigned using quantum mechanical driven 1H …

In order to discover novel probes that may help in the investigation and control of infectious
diseases through a new mechanism of action, we have evaluated a library of phenol-based …

The skyllamycins are a class of heavily modified, non-ribosomal peptides, first isolated from
Streptomyces sp. KY11784. A Streptomyces strain with potent antibiotic activity against …

Introduction Nuclear magnetic resonance (NMR) spectroscopy is increasingly employed in
the quantitative analysis and quality control (QC) of natural products (NP) including …

This review aims at providing an analysis of the various available reference methods in
nuclear magnetic resonance, based on recent literature. This paper will provide a tool to …
