Dihydroisocoumarins

Phyllodulcin is a dihydroisocoumarin found in Hydrangea macrophylla and Hydrangea serrata. It is a sweetener 400–800 times sweeter than sugar.

Hydrangenol is a dihydroisocoumarin. It can be found in Hydrangea macrophylla, as well as its 8-O-glucoside. (−)-Hydrangenol 4′-O-glucoside and (+)-hydrangenol 4′-O-glucoside can be found in Hydrangeae Dulcis Folium, the processed leaves of H. macrophylla var. thunbergii.

Monocerin is a dihydroisocoumarin and a polyketide metabolite that originates from various fungal species. It has been shown to display antifungal, plant pathogenic, and insecticidal characteristics. Monocerin has been isolated from Dreschlera monoceras, D. ravenelii, Exserohilum turcicum, and Fusarium larvarum.

Xylindein is a quinone pigment, a dimeric naphthoquinone derivative. It is produced by fungi in the genus Chlorociboria. This pigment causes green staining of wood infected by the fungi.

6-Hydroxymellein is a dihydroisocoumarin, a phenolic compound found in carrots. It has also been isolated in Aspergillus terreus and shows an inhibition of pollen development in Arabidopsis thaliana.

Mellein is a dihydroisocoumarin, a phenolic compound produced by the mold species Aspergillus ochraceus.

6-Methoxymellein is a dihydroisocoumarin, a phenolic compound found in carrots and carrot purées. It is responsible for bitterness in carrots. It is a phytoalexin, induced in carrot slices by UV-C, that allows resistance to Botrytis cinerea and other microorganisms.
