The Spatial Distribution of Alkaloids in Psychotria prunifolia (Kunth) Steyerm and Palicourea coriacea (Cham.) K. Schum Leaves Analysed by Desorption Electrospray Ionisation Mass Spectrometry Imaging
ConclusionDifferent distributions were found for three alkaloids in Psychotria prunifolia, and the distributions found by MSI were in complete accordance with HPLC–MS analysis and histochemical results. The DESI‐MSI technique was therefore demonstrated to provide reliable information about the spatial distribution of metabolites in plants. Copyright © 2017 John Wiley & Sons, Ltd.

Validated Method for Strigolactone Quantification by Ultra High ‐Performance Liquid Chromatography – Electrospray Ionisation Tandem Mass Spectrometry Using Novel Deuterium Labelled Standards
ConclusionA method was developed for determining endogenous fabacyl acetate and orobanchyl acetate in plant tissue based on novel deuterium labelled standards. A method of orobanchol quantification using a synthetic SL GR24 as internal standard was proposed. Copyright © 2017 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)

Quantification of the Pyrrolizidine Alkaloid Jacobine in Crassocephalum crepidioides by Cation Exchange High ‐Performance Liquid Chromatography
ConclusionThe developed method is sufficiently sensitive for reproducible detection of jacobine in C. crepidioides. Simple sample preparation and rapid separation allows for quantification of jacobine in plant material in a high‐throughput manner. Thus, the method is suitable for genetic screenings and may be applicable for other plant species, for instance Jacobaea maritima. In addition, our results show that C. crepidioides cannot be considered safe for human consumption. Copyright © 2017 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)

Screening of Hallucinogenic Compounds and Genomic Characterisation of 40 Anatolian Salvia Species
ConclusionThis is the first report of screening 40 Salvia species in Turkey according to their psychoactive constituents, salvinorin A and salvinorin B and their genomic structures. It is possible that some of these Salvia species may exhibit some psycho activity. Thus, they need to be screened further. Copyright © 2017 John Wiley & Sons, Ltd. (Source: Phytochemical Analysis)

Quantitative Analysis of Ingenol in Euphorbia species via Validated Isotope Dilution Ultra ‐high Performance Liquid Chromatography Tandem Mass Spectrometry
ConclusionThe newly established UHPLC–MS/MS method shows to be an appropriate tool for screening of the Euphorbia genus for ingenol content and allows selection of species suitable for raw material production and/or in vitro culture initiation. Copyright © 2017 John Wiley & Sons, Ltd.
Ingenol is the key precursor for the synthesis of ingenol mebutate (angelate), used to treat actinic keratosis.
Various species of the Euphorbia genus contain diterpene ingenol and ingenol mebutate (ingenol‐3‐angelate), a substance found in the sap of the plant Euphorbia peplus and an inducer of cell death. An ultra‐high perform...

Identification of some Bioactive Metabolites in a Fractionated Methanol Extract from Ipomoea aquatica (Aerial Parts) through TLC, HPLC, UPLC ‐ESI‐QTOF‐MS and LC‐SPE‐NMR Fingerprints Analyses
ConclusionThe HPLC and TLC results showed that HPLC fingerprints give more and better separated peaks, but TLC helped in determining the class of the active compounds in some fractions. Bioactive constituents were identified as well using MS and NMR analyses. Two flavonoids and two phenolic compounds were tentatively identified in this species for the first time, to the best of our knowledge. Copyright © 2017 John Wiley & Sons, Ltd.
