Proazulene, also known as matricine, is a member of the class of compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Thus, proazulene is considered to be an isoprenoid lipid molecule. Proazulene is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Proazulene can be found in anise, which makes proazulene a potential biomarker for the consumption of this food product. Chamazulene, a blue-violet derivative of azulene, found in a variety of plants including in chamomile (Matricaria chamomilla), wormwood (Artemisia absinthium) and yarrow (Achillea millefolium) is biosynthesized from matricin .

Cumambrin a 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. Cumambrin a is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Cumambrin a can be found in sweet bay, which makes cumambrin a a potential biomarker for the consumption of this food product.
