Fig. 3. NMR images of transverse slice across ajowan schizocarp (A and B) and mericarp (C and D). Spatial resolution is 25 µm × 25 µm and slice thickness is 300 µm. A, Non‐selective image of overall lipid distribution, comprising reserve oil and thymol; B, same image as in A showing location of oil canals; C, chemical shift selective image (δ = 5·2 ppm) of reserve oil (triglyceride) distribution; D, chemical shift selective image (δ = 6·2 ppm) of thymol distribution. The image corresponds with the location of the canals as shown in Fig. 1B, and confirms that thymol is localized in the canals.
