Non-invasive localization of thymol
The fruits of many plants in the family Apiaceae accumulate essential oil in canals of the fruit wall. Using chemical shift selective MRI, Gersbach and Reddy (pp. 253-257) identify accumulation sites of thymol and other components from NMR images of Carum copticum fruits. The technique is non-invasive, and provides a significant advantage over conventional histochemical methods involving embedding, cutting and staining.
