Selective extraction of bioactive compounds from plants using recent extraction techniques: A review.

Plant extraction has existed for a long time and is still of interest. Due to technological improvements, it is now possible to obtain extracts with higher yields. While global yield is a major parameter because it assesses the extraction performance, it can be of interest to focus on the extraction of particular compounds (specific metabolites) to enrich the sample and to avoid the extraction of unwanted ones, for instance the primary metabolites (carbohydrates, triacylglycerols).

Development of an analytical method for chlorophyll pigments separation by reversed-phase supercritical fluid chromatography.

Chlorophyll pigments give the green colour to plants, which is a quality attribute of food and vegetables. However, the chemical structure of native chlorophyll can change during varied processes (drying, freezing, extraction) applied to plants, which produce degradation compounds that could have a brown and unwanted colour. Systematic experiments have been conducted in supercritical fluid chromatography with a C18 stationary phase to understand and model the chromatographic behaviour of the compounds with respect to the nature of the modifier (MeOH, ACN, and MeOH/ACN 50/50) and its percentage, from 10% to 100%.
