“…This seems to greatly facilitate the adsorption and consequently the interaction with organic compounds, like gentiopicroside ( 1 ) and amarogentin ( 2 ), presumably due to interactions of a lipophilic nature or of the van der Waals type. The present results confirm a trend exhibited by these same materials (especially by Mg Al azelate, entry E) with other classes of natural products like anthraquinones, phenolic acids, flavonoids, purine alkaloids, diarylheptanoids, capsaicinoids, oxyprenylated coumarins, apocarotenoids, and anthocyanins …”

In a search for methods of manufacturing bitter principles from Gentiana lutea, mainly represented by gentiopicroside (1) and amarogentin (2), as an alternative to extraction from the roots of this plant, in this short communication it is shown that the leaves of this plant can be regarded as an additional source of such phytochemicals. Extraction of G. lutea leaves was coupled to solid-phase adsorption by differently structured solids as a separation technology step, providing a selective isolation of both these secondary metabolites in good to excellent yields. Thus, the extraction of bitter secoiridoids can be achieved in an equivalent or improved way rather than processing the roots of G. lutea while preserving the biodiversity of the species.

“…38 During the last three years, lamellar solids have found extensive use in phytochemistry and have been shown to be tremendously efficient for the selective extraction of classes of plant secondary metabolites like flavonoids, catechins, alkaloids, 39 diarylheptanoids, 40 bitter secoiridoids, 41,42 capsaicinoids, 43 oxyprenylated coumarins, 44 tetraterpenes, 45 and anthocyans. 46 48 The pattern of adsorption was practically the same, allowing good to excellent recovery of anthraquinones (all or some) by using the same two sorbents mentioned above in addition to magnesium aluminum azelate, which also displayed good performance. Among the five anthraquinones assayed, rhein (5) was the one adsorbed to the highest extent.…”

“…Thus, no appreciable loss of adsorption capacities by both solid supports was observed upon their recycling after each experiment. Encouraged by these preliminary results, Epifano and coworkers extended the study about the effectiveness of lamellar solids for the selective extraction of anthraquinones to a panel of five further molecules, namely emodin ( 1 ), aloe‐emodin ( 6 ), rhein ( 5 ), chrysophanol ( 2 ), and physcion ( 3 ), from three ethanolic extracts of well‐known plants with purgative effects (frangula, senna, and rhubarb) 48 . The pattern of adsorption was practically the same, allowing good to excellent recovery of anthraquinones (all or some) by using the same two sorbents mentioned above in addition to magnesium aluminum azelate, which also displayed good performance.…”

Introduction: Solid-phase extraction applied to plant matrices is nowadays a wellvalidated technique allowing to concentrate and purify different secondary metabolites. Several classes of phytochemicals have been selectively extracted by this methodology. During the last decade attention has been focused on biologically active anthraquinones from numerous sources like edible, healthy, and medicinal plants. Objectives: The aim of this review is to provide a detailed literature survey of the solid-phase adsorption methodologies for the extraction of natural anthraquinones reported so far and to discuss and propose future directions in this field of research. Materials and Methods: Substructure search was performed in the SciFinder Scholar, PubMed, Medline, and Scopus databases. Results: The first report about application of solid-phase adsorption for the purification of anthraquinones appeared in the literature in 2002. From this date, and in particular during recent years, the most notable examples included the use of chitin-and chitosan-based polymers, of molecularly imprinted polymers, of coated magnetic nanoparticles, of miniaturized matrix solid-phase dispersion, of functionalized resins, of differently structured lamellar solids, and finally of vortex-synchronized matrix solid-phase dispersion. Conclusions:The herein detailed solid-phase adsorption methodologies are powerful tools to selectively extract natural anthraquinones and/or provide anthraquinoneenriched phytopreparations. Nevertheless, many other important methods have been applied to synthetic anthraquinones (e.g., azo dyes). These could be conveniently employed also for natural anthranoids. Studies in this field are discussed in this review article.
