With the molecular formula C17H28O3S1, and knowing it’s found in aspen root exudate, this could be jasmonyl sulfate or a related compound. Jasmonates are plant hormones, and their sulfated derivatives have been found in root exudates.
However, I should note that while I can suggest this based on the formula and source, without access to spectroscopic data or primary literature confirmation, I cannot be completely certain. The same molecular formula could potentially correspond to other compounds as well.
Would you be able to share any additional analytical data about this compound, such as:
- Mass spectrometry data
- NMR spectra
- Or other structural characterization information?
This would help make a more definitive identification.
