Estimation of the metabolite complement of plant material involves a wide range of techniques and technologies and that breadth continues to increase. Metabolomics research typically involves multiple sites for material preparation and analysis and most investigations are ¿high throughput¿, meaning that chemical analysis of sample sets are inevitably carried out over an extended period of time. In, Plant Metabolomics: Methods and Protocols expert researchers in the field detail many of the stages which are now commonly used to study plant metabolomics workflow. Stages of this workflow, up to and including the statistical analysis, accurate and detailed collection of meta-data are also essential for good process management,
