Origin Discrimination of Osmanthus fragrans var. thunbergii Flowers using GC –MS and UPLC‐PDA Combined with Multivariable Analysis Methods
ConclusionsGC–MS and UPLC‐PDA combined with multivariable analysis methods can discriminate the origin of Osmanthus fragrans var. thunbergii flowers. Copyright © 2017 John Wiley & Sons, Ltd.
PCA was used to qualitatively discriminate the origins, however, SIMCA and RF were used to make classification models. Six effective compounds from GC‐MS and four effective compounds from UPLC‐PDA for discrimination were obtained by the PCA loadings. The RF model based on the four effective compounds from UPLC‐PDA data obtained good result to differentiate the origins. (Source: Phytochemical Analysis)

C18 ‐COOH Silica: Preparation, Characterisation and Its Application in Purification of Quaternary Ammonium Alkaloids from Coptis chinensis
ConclusionA multi‐functionalised silica was synthesised via “click chemistry”. As the high‐performance liquid chromatographic stationary phase, the C18‐COOH silica could be operated in trimodal reversed‐phase/weak cation exchange/hydrophilic interaction mode. The C18‐COOH silica also exhibited potential as solid‐phase extraction sorbent in the purification of quaternary ammonium alkaloids from complex matrices. Copyright © 2017 John Wiley & Sons, Ltd.

Recent Advances in Effect ‐directed Enzyme Assays based on Thin‐layer Chromatography
Abstract
Thin‐layer chromatography (TLC) together with its more modern form high‐performance thin‐layer chromatography (HPTLC) is a rapid and cost effective analytical tool with a long tradition in quality control of medicinal plants, extracts and natural products. Separated compounds are fixed on the solid silica phase to form a compound library. Through direct coupling of visualisable enzyme reactions on the TLC plate, this compound library can also be used for activity screening. Such TLC‐based bioautographic enzyme and enzyme inhibition assays complement first stage development activity screening assays. They p...
