Sample preparation for chromatographic analysis of plant material


, : Sample preparation for chromatographic analysis of plant material. Journal of Planar Chromatography - Modern TLC 13(6): 404-413, November-December

Chromatography is the main technique used for analysis of organic compounds in plant material. Preparation of plant samples for chromatographic analysis is a complex, multistage process, and the procedures used vary depending on the goals of the determination. This paper discusses all stages of sample preparation, from sampling, through extraction, to quality assurance and quality control (QA/QC). Modern sample-preparation techniques, including accelerated solvent extraction, supercritical-fluid extraction, microwave-assisted extraction and sonication, are reviewed in the context of plant material analysis. Steps involved in QA/QC are presented and discussed.

Teeth that have suffered trauma can fuse to the surrounding bone in a process called dental ankylosis. Ankylosed permanent front teeth fail to erupt during facial growth and can become displaced, thus resulting in functional and aesthetic problems...

Aging involves neuronal and synaptic loss, and maintenance of function depends on adaptations in cellular responsiveness. We studied olfactory bulbectomy (OBX), a model that recapitulates monoaminergic dysfunction in depression, in 10-week vs 19-m...

In general, it may be said that tinned steel was most susceptible to corrosion, followed in order by Al,...
