  2. Dietary burden of phenolics per serving of "Mountain tea" (Sideritis) from Macedonia and correlation to antioxidant activity.

    Natural product communications 6(9):1305 (2011) PMID 21941904

    This work was afforded from 2 points of view, phytochemical evaluation and relation to antioxidant activity and dietary burden of phenolics of a cup of "Mountain tea", a drink obtained by domestic infusion of Sideritis. Phytochemically, two extraction protocols using water and methan...
  3. Approach to the study of C-glycosyl flavones acylated with aliphatic and aromatic acids from Spergularia rubra by high-performance liquid ch...

    Rapid Communications in Mass Spectrometry 25(6):700 (2011) PMID 21337631

    The use of mass spectrometry (MS) coupled to liquid chromatography (LC) as working tool for the study of the C-glycosyl flavones acylated with aliphatic and aromatic acids has allowed the tentative characterization of these compounds in Spergularia rubra and the establishment of the...
  4. Rumex induratus leaves: interesting dietary source of potential bioactive compounds.

    Journal of Agricultural and Food Chemistry 54(16):5782 (2006) PMID 16881678

    The phenolic compounds of Rumex induratus leaves were determined by HPLC-DAD-MS/MS-ESI. The results revealed a profile composed of 19 compounds: caffeoyl-hexoside, two p-coumaroyl-hexoside isomers, feruloyl-hexoside, sinapoyl-hexoside, 6-C-hexosyl-quercetin, 8-C-hexosyl-luteolin, 6-C-hexosyl-luteoli...
  5. Structural characterization of phenolics and betacyanins in Gomphrena globosa by high-performance liquid chromatography-diode array detectio...

    Rapid Communications in Mass Spectrometry 25(22):3441 (2011) PMID 22002699

    The metabolite profiling of Gomphrena globosa inflorescences was performed by high-performance liquid chromatography-diode array detection/electrospray ionization multi-stage mass spectrometry (HPLC-DAD/ESI-MS(n) ). Based on the fragmentation patterns, 24 phenolic compounds were char...
  6. Iron deficiency enhances bioactive phenolics in lemon juice.

    Journal of the Science of Food and Agriculture 91(12):2132 (2011) PMID 21560131

    BACKGROUND This study was designed to describe the phenolic status of lemon juice obtained from fruits of lemon trees differing in iron (Fe) nutritional status. Three types of Fe(III) compound were used in the experiment, namely a synthetic chelate and two complexes derived from natu...
