  5. 3. Sample preparation and analysis of metabolites from plants in the families of Cyperaceae, Poaceae and Apiaceae

    Author : Linus Svenberg; Åsa Emmer; Jenny Lindh; Margareta Sandahl; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gas chromatography; Mass spectrometry; Ultrasound assisted extraction; Solid-phase microextraction; Volatile compounds; Allelopathy; Bioassay; Gaskromatografi; Masspektrometri; Ultraljudsassisterad extraktion; fastfas-mikroextraktion; Flyktiga ämnen; Allelopati; Bioanalys; Kemi; Chemistry;

    Abstract : An important aspect of understanding how plants effect their environmentis the study of volatile compounds and how these influence interactions between plants and other living organisms. The study of these secondary metabolites from plants can be used in practical applications, such as behaviour control of insects, and is an important part in the search for novel compounds that can be used to influence the behaviour of disease spreading vectors.
