The paper of M. J. Kato et al. demonstrates the GC- MS monitoring of the major secondary metabolites and fatty acids occurring in the seeds of Virola surinamensis, duringgerminationandseedlingdevelopment.Theauthors conclude that the germination of V. surinamensis seeds and the seedling development are processes in which both fatty acidsandsecondarymetabolites(lignans,isoflavonoidsand juruenolides) are equally consumed in the seeds indicating their potential physiological role as energy and carbon sources. The article of P. J. Gates and N. P. Lopes describes the application of negative ion chip-based nanospray tandem mass spectrometry for the analysis of flavonoid aglycones. The methodology is tested by the analysis of a crude green tea extract, where the expected flavonoids were readily identified.
