Fig. 4 Sampling area for DMI-GC/MS analysis of the coriander leaf and root
1) A plant of coriander. 2) Magnified view of the coriander leaf. Red rectangles denote vines, while blue ellipses denote the spaces between the vines.
3) Magnified view of a coriander root slice. Blue circles (ᶉ – ᶋ) and ᶌ have been targeted. The area indicated by the red arrow ᶌdenotes the surface of the
coriander root. All areas are cut off, and each piece is used for DMI-GC/MS analysis, similar to the prepared sample Fig. 1.
