Pentalenolactone F
A tetracyclic sesquiterpene lactone obtained by formal epoxidation of the 4-methylene group of pentalenolactone E.
Artecanin
Artecanin belongs to guaianolides and derivatives class of compounds. Those are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. Artecanin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Artecanin can be found in sweet bay, which makes artecanin a potential biomarker for the consumption of this food product.

11-Hydroxy-12-methoxydihydrokawain is found in beverages. 11-Hydroxy-12-methoxydihydrokawain is a constituent of Piper methysticum (kava). FDA advises against use of kava in food due to potential risk of severe liver damage (2002)
Tyrosyl-Proline
Tyrosyl-Proline is a dipeptide composed of tyrosine and proline. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
