3,4-Dehydro-6-hydroxymellein is a member of isocoumarins. 3,4-Dehydro-6-hydroxymellein has been reported in Conoideocrella tenuis, Streptomyces, and other organisms with data available.

Noreugenin, also known as 5,7-dihydroxy-2-methyl-4h-1-benzopyran-4-one, is a member of the class of compounds known as chromones. Chromones are compounds containing a benzopyran-4-one moiety. Noreugenin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Noreugenin can be found in carrot and wild carrot, which makes noreugenin a potential biomarker for the consumption of these food products.
