Applications of in vivo and in vitro solid-phase microextraction techniques in plant analysis: A review

• Recent applications of SPME in plant analysis are summarized.
• Characteristics of the applications are discussed.
• Future development of SPME in plant analysis is prospected.

As a very popular sample preparation technique, solid-phase microextraction (SPME) coupled with various analytical instrumentation, has been widely used for the determination of trace levels of different plant compounds, such as volatile organic compounds (VOCs) emitted from the different plant organs, and environmental contaminants in plants. In this review, recent applications of in vitro and in vivo SPME in plant analysis are discussed and summarized according to the different organs of plants, including fruits, flowers, leaves, stems, roots and seeds, and the whole plant as well. Future developments and applications of SPME in plant analysis, especially in vivo sampling approaches, are also prospected.
