  1. Optimisation of supercritical fluid extraction of indole alkaloids from Catharanthus roseus using experimental design methodology--comparison with other extraction techniques.

    Phytochemical Analysis 19(1):52 (2008) PMID 17654538

    Response surface modelling, using MODDE 6 software for Design of Experiments and Optimisation, was applied to optimise supercritical fluid extraction (SFE) conditions for the extraction of indole alkaloids from the dried leaves of Catharanthus roseus. The effects of pressure (200-400 bar), tempe...
  2. Simultaneous quantification of five triterpenoid saponins in Clematis L. spp. by high-performance liquid chromatography with evaporative light scattering detection.

    Phytochemical Analysis 19(1):40 (2008) PMID 17654533

    A simple and accurate method involving high-performance liquid chromatography with evaporative light scattering detection was developed for the simultaneous determination of five triterpenoid saponin components in Clematis L. spp. for the first time. The analysis was performed on a Zorbax SB-C(1...
  3. Isoflavones in the Rutaceae family: twenty selected representatives of the genera Citrus, Fortunella, Poncirus, Ruta and Severinia.

    Phytochemical Analysis 19(1):64 (2008) PMID 17654537

    Enzyme-linked immunosorbent assays in combination with semi-preparative high-performance liquid chromatography (HPLC) and analytical HPLC with mass spectroscopy in the selective ion monitoring mode were used for the determination of selected isoflavones, daidzein, genistein, biochanin A and thei...
  4. Selective analysis of phenolic compounds in propolis by HPLC-MS/MS.

    Phytochemical Analysis 19(1):32 (2008) PMID 17654520

    Phenolic compounds (flavonoids and phenolic acid derivatives) are major active constituents of the resinous fraction of propolis, and also represent its allergenic principles. We have developed a chromatography electrospray ionisation tandem mass spectrometry (HPLC-ESI-MS/MS) method to character...
  5. Quantitative analysis by HPLC-MS2 of the pyrrolizidine alkaloid adonifoline in Senecio scandens.

    Phytochemical Analysis 19(1):25 (2008) PMID 17879229

    A quantitative method using HPLC-MS(2) has been developed for the determination of adonifoline, one of the retronecine-type hepatotoxic pyrrolizidine alkaloids in Senecio scandens Buch.-Ham. ex D. Don., a traditional Chinese herb. Using an orthogonal design test, a simple and rapid sample extrac...
  6. High-performance liquid chromatographic separation and identification of polyphenolic compounds from the infusion of Davilla elliptica St. Hill.

    Phytochemical Analysis 19(1):17 (2008) PMID 17654510

    The isolation of polyphenolic compounds from an infusion of the Brazilian plant Davilla elliptica (Dilleniaceae), used as tea by virtue of its digestive properties, is described. An improved preparative HPLC method was used in order to isolate pure polyphenols from the complex mixture. Liquid-li...
  7. Analysis of ellagic acid in pomegranate rinds by capillary electrophoresis and high-performance liquid chromatography.

    Phytochemical Analysis 19(1):86 (2008) PMID 18229889

    Two novel methods for the analysis of ellagic acid in pomegranate (Punica granatum) rinds are proposed. Capillary electrophoresis (CE) was performed in a bare fused-silica capillary using a buffer solution of tri(hydroxymethyl)aminomethane:potassium dihydrogen phosphate (pH 8.4) with an applied ...
  8. Primary flavonoids in marigold dye: extraction, structure and involvement in the dyeing process.

    Phytochemical Analysis 19(1):46 (2008) PMID 17654539

    Flavonoids extracted from marigold flowers were investigated for their dyeing potential. Patulitrin (1) and patuletin (2) were isolated and their structures established using NMR and HPLC-MS. These compounds were identified as the main flavonoids present in the dyeing bath. Following the dyeing ...
  9. Recent methodology in the phytochemical analysis of ginseng.

    Phytochemical Analysis 19(1):2 (2008) PMID 18058794

    This review summarises the most recent developments in ginseng analysis, in particular the novel approaches in sample pre-treatment and the use of high-performance liquid-chromatography-mass spectrometry. The review also presents novel data on analysing ginseng extracts by nuclear magnetic reson...
