The use of chromatographic assays to assess the residual complexity of materials that are purified from natural sources by chromatographic means is, in a sense, a case of the fox watching the henhouse. Beside their static residual complexity, which is intrinsic to their metabolic origin, biologically active natural materials can also be involved in chemical reactions that lead to dynamic residual complexity. The present study examines the dynamics of the hop prenylphenol, desmethylxanthohumol…

Dynamic residual complexity of the isoliquiritigenin-liquiritigenin interconversion during bioassay.
TLDR
This time-resolved study investigates the isomerization of isoliquiritigen in and liquiritigenin in two culture media with and without MCF-7 cells, and demonstrates how both nonchiral reactions and enantiomeric discrimination can occur in bioassay media, with or without cells.
Isolation and structural characterization of dihydrobenzofuran congeners of licochalcone A.
Dynamic changes in composition of extracts of natural products as monitored by in situ NMR
TLDR
The direct in situ NMR observation and quantification of the inter‐conversion of secoiridoid derivatives due to temperature and solvent effects is demonstrated in complex extracts of natural products without prior isolation of the individual components.
Analysis and Purification of Bioactive Natural Products: The AnaPurNa Study
TLDR
The study provides numerical measures of the common means of sourcing NPs, the chromatographic methodology employed for NP purification, and the role of spectroscopy and purity assessment in NP characterization.
Countercurrent Separation of Natural Products: An Update
TLDR
The goals of this review are to deliver the necessary background with references for an up-to-date perspective of CCS, to point out its potential for the natural product scientist, and thereby to induce new applications in natural product chemistry, metabolome, and drug discovery research involving organisms from terrestrial and marine sources.
Dereplication, residual complexity, and rational naming: the case of the Actaea triterpenes.
TLDR
Two new tools are developed that enable rapid dereplication of more than 170 known triterpenes and facilitates elucidation of new compounds and a predictive computational model based on classification binary trees (CBT) allows in silico determination of the aglycone type.
Orthogonal Analysis Underscores the Relevance of Primary and Secondary Metabolites in Licorice
TLDR
The combined orthogonal methods enable the mass balance characterization of licorice extracts and highlight the relevance of 1°Ms, and accompanying metabolites, for botanical quality control.
Analytical condition setting a crucial step in the quantification of unstable polyphenols in acidic conditions: analyzing prenylflavanoids in biological samples by liquid chromatography-electrospray ionization triple quadruple mass spectrometry.
TLDR
It was concluded that a neutral pH (pH 7.0) is necessary for the analysis of prenylflavanoids, in order to maintain the stability of compounds for at least 24 h.
