GC ‐MS and q‐NMR based chemotaxonomic evaluation of two Leonurus species
ConclusionThe major components in Leonurus panzerioides and L. turkestanicus as identified by the GC–MS and q‐NMR analyses, were similar to those present in other Leonurus species and thus provided chemotaxonomic evidence for the placement of these species under the genus Leonurus.

Profiling and Simultaneous Quantitative Determination of Anthocyanins in Wild Myrtus communis L. Berries from Different Geographical Areas in Sardinia and their Comparative Evaluation
ConclusionThe developed methodology allows the identification of quali‐quantitative differences among M. communis samples and thus defines the quality and value of this raw material for marketed products. Moreover, the reported data have an immediate commercial value due to the current interest in developing antioxidant nutraceuticals from Mediterranean plants, including Sardinian Myrtus communis.

Ultra‐high Performance Liquid Chromatography with Photodiode Array and Chemiluminescence Detection for the Determination of Polyphenolic Antioxidants in Erigeron acris L. Extracts
ConclusionCoupling of UHPLC with CL detection has been developed for the first time. This advanced chromatographic technique coupled with sensitive CL detection is a powerful approach for the investigation of polyphenolic profiles in natural products. The shorter analysis time and diminished waste generation makes the UHPLC method more environmentally friendly and more cost‐effective in comparison with conventional HPLC.

Supercritical Extraction of Scopoletin from Helichrysum italicum (Roth) G. Don Flowers
ConclusionThe extraction conditions, especially pressure, exhibited significant influence on the extraction yield as well as the yield of extracted scopoletin and antioxidant activity of extracts. Copyright © 2016 John Wiley & Sons, Ltd.
Supercritical CO2 extraction of H. italicum flowers at different values of pressure and temperature was performed in order to optimize the extraction process using response surface methodology in terms of getting higher extraction yield and yield of scopoletin. The greatest extraction yield and the highest yield of scopoletin were obtained under extraction conditions of 20 MPa and 40...

Metabolomic Fingerprinting of Romaneschi Globe Artichokes by NMR Spectroscopy and Multivariate Data Analysis
ConclusionMetabolomic approach coupling NMR spectroscopy with multivariate data analysis allowed for a detailed metabolite profile of artichoke and cardoon varieties to be obtained. Relevant differences in the relative content of the metabolites were observed for the species analysed. This work is the first application of 1H‐NMR with multivariate statistics to provide a metabolomic fingerprinting of Cynara scolymus. Copyright © 2016 John Wiley & Sons, Ltd.

Pro ‐toxic 1,2‐Dehydropyrrolizidine Alkaloid Esters, Including Unprecedented 10‐Membered Macrocyclic Diesters, in the Medicinally‐used Alafia cf. caudata and Amphineurion marginatum (Apocynaceae: Apocynoideae: Nerieae and Apocyneae)
ConclusionsThe presence of pro‐toxic dehydropyrrolizidine alkaloids suggests that medical preparations of these plants pose potential health risks to consumers. Dehydropyrrolizidine alkaloids are evidently more widespread in Apocynoideae than previously assumed, and it would seem rewarding to study other members of this family for the presence of pyrrolizidines, dehydropyrrolizidines and dihydropyrrolizines.
