A 1H-NMR metabolomic fingerprinting of 14 Globe artichoke populations, based on apolar and polar extracts of edible heads and spectral integration followed by principal component analysis, provided identification and quantification of major classes of organic compounds. The Italian landraces Bianco di Pertosa zia E and Natalina showed the highest content of nutraceuticals, including highly unsaturated long chain lipids, organic acids, amino acids, sugars (mainly inulin), caffeoyl derivatives (mainly cynarin), flavonoids and terpenes.

A validated Ultra-high-performance liquid chromatography coupled with hybrid triple quadrupole-linear ion trap mass spectrometry (UHPLC-QqQLIT-MS/MS) method was developed for quantitation of bioactive compounds in roots and leaves of seven Rauwolfia species. Root of Rauvolfia vomitoria showed a high content of ajmaline (48.43 mg/g), serpentine (87.77 mg/g) whereas high quantities of yohimbine (100.21 mg/g) and ajmalicine (120.51 mg/g) were detected in R. tetraphylla. High content of reserpine was detected in R. micrantha (35.18 mg/g) and R. serpentina (32.38 mg/g).

To establish the taxonomic status of Leonurus panzerioides and L. turkestanicus based on their chemical constituents analysed by GC–MS and q-NMR. The q-NMR analyses of Leonurus panzerioides and L. turkestanicus revealed the presence of 8-acetylharpagide, harpagide, leonurine and stachydrine as major components. The major constituents of the essential oil of L. panzerioides were eugenol (30.9%) and p-vinyl guaiacol (15.8%), whereas thymol (40.1%) and octen-3-ol (13.1%) were the principal compounds in the essential oil of L. turkestanicus.
- Supercritical Extraction of Scopoletin from Helichrysum italicum (Roth) G. Don Flowers
Stela Jokić, Marina Rajić, Blanka Bilić and Maja Molnar
Version of Record online: 20 JUL 2016 | DOI: 10.1002/pca.2630
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°C. Extracts have also proven to possess antioxidant activity influenced by both temperature and pressure applied within the investigated parameters.
