      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 performance liquid chromatography tandem mass spectrometry-based screening method suitable for quantitative analysis of ingenol in 38 species of the Euphorbia genus was developed. The 18O–labelled ingenol analogue was used as an internal standard for ingenol content determination and method validation.

      Version of Record online: 2 AUG 2017 | DOI: 10.1002/pca.2712

      Qualitative and quantitative analysis of flavonoids and phenolic acids in methanol extracts of aerial flowering parts of 28 Hieracium species from the Balkans was performed by LC-MS. Multivariate statistical data analysis included nMDS, UPGMA and PCA. Chemical analysis demonstrated that these metabolites are good indicators of chemosystematic relationships within Hieracium, particularly between non-hybrid species and groups from the same location. The antioxidant potential of the extracts, evaluated using three colorimetric tests, was satisfactory and in accordance with their phenolics composition.

      Version of Record online: 25 JUL 2017 | DOI: 10.1002/pca.2708

      Conditions for the most efficient polyphenol extraction from C. Ragusina L. were determined: the 80% EtOH/water solvent system for callus and leaf ex vitro samples and 80 or 96% EtOH for leaf in vivo samples. Significantly higher levels of chlorogenic acid and naringenin were detected in callus tissue than in wild plant. Ethanolic extracts exhibited the significant antibacterial activity against Staphylococcus aureus ATCC 25923. DNA/RNA active compounds in plant extracts were detected by thermal denaturation and circular dichroism methods.

      Version of Record online: 19 JUL 2017 | DOI: 10.1002/pca.2702

      This study revealed the potential of integrating NMR-MAS and transcriptomic data. The primary metabolites were up-regulated by water deficiency and were properly assigned in the 1H HR-MAS spectrum, rigid and semi-rigid polysaccharides were readily observed using CP-MAS and mobile components were observed by SPE-MAS during the SSNMR analysis. In addition, multiple copies of the genes involved in the biosynthesis of the compounds affected by the water deficiency were identified in the soybean genome.

      SC-CO2 extraction of lavender flowers was performed under different parameters determined by Box-Behnken design. The interaction between the pressure and CO2 flow rate as well as between the temperature and CO2 flow rate showed statistically significant influence on the yield. The optimum extraction conditions for higher monoterpenes and lower coumarin content were at 10 MPa, 41°C and CO2 flow rate 2.3 kg/h, and at 30 MPa, 50°C and CO2 flow rate 3 kg/h for higher monoterpenes and coumarin content.

      Version of Record online: 12 JUL 2017 | DOI: 10.1002/pca.2706

      The phytochemical investigation of different Soldanella species resulted in the isolation of three oleanane-type saponins, two being new natural products, and the development of an HPLC method for their separation. For the latter Hydrophilic Interaction Liquid Chromatography and Evaporative Light Scattering Detection were used. Method validation confirmed that the assay meets all respective requirements, and quantitative results revealed a total saponin content ranging from 1.09 % (S. montana leaves) to 5.14 % (S. alpina roots).

      Version of Record online: 7 JUL 2017 | DOI: 10.1002/pca.2701

      The flavonoid pattern of a typical Citrus sinensis variety, an original product of the Calabria region, namely Tarocco Lempso, has been investigated thoroughly. The qualitative/quantitative profiling was performed using a UHPLC-PDA-IT-TOF platform. Moreover, a precolumn DPPH assay coupled to UHPLC-PDA was developed as a fast antioxidant screening method. The entire protocol takes only 50 min per sample, comprising of reaction and analysis. The developed method highlighted higher amount of flavanones and a better antioxidant activity of Lempso clone, in comparison with other Citrus varieties.

      Version of Record online: 2 JUL 2017 | DOI: 10.1002/pca.2704

      An HPLC method for quantification of caffeoylquinic acid derivatives in Hieracium pilosella has been developed and validated. Samples of H. pilosella were prepared by extraction of dried plant material with methanol. Individual substances in the methanol extract were identified by analyses of UV-MS/MS spectra and verified by comparisons with authentic reference substances. The content of caffeoylquinic acid derivatives was determined and expressed as chlorogenic acid. In analyses of 12 batches of H. pilosella contents of caffeoylquinic acid derivatives ranging from 0.7 to 1.9% were found.

      Version of Record online: 19 JUN 2017 | DOI: 10.1002/pca.2700

      A new method for the structural elucidation of Annonaceous acetogenins was based on supercritical fluid chromatography coupled to high resolution tandem mass spectrometry, including lithium post-column cationisation. This method appeared as sensitive as classical liquid chromatography coupled to the same mass spectrometer but significantly improved the chromatographic resolution and thus allowed the annotation of a new group of isomers of montanacin-D.

      Version of Record online: 13 JUN 2017 | DOI: 10.1002/pca.2697

      Phlorotannins in Laminaria digitata were characterised. 13C NMR spectroscopy revealed a fucol-to-phlorethol linkage type ratio of 1:26. Quantitative 1H NMR spectroscopy allowed determination of the response factors required for colorimetric quantification by the DMBA-assay. Mass fragmentation data and 13C NMR spectroscopy (an average number of 1.5 hydrogen atoms per benzene ring) data indicated the presence of branched phlorotannin isomers. MALDI-TOF-MS analysis showed the presence of oligomeric phlorotannins up to DP27.

      A modified matrix solid phase dispersion (MSPD) methodology was developed for analysing flavonoid aglycones in rape bee pollen. The method comprises a MSPD procedure using silica gel as sample disruptor, followed by packing into the column of constant pressure funnel. By refluxing with acid aqueous ethanol solution, the extraction and hydrolysis were accomplished in one step. Compared with already available methods, the present work showed advantages of time and labor saving, higher extraction efficiency and less consumption of acid catalyst.
