Common Name

(3as,6r,6as,8r,9ar,9br)-6-hydroxy-6-methyl-3,9-dimethylidene-8-{[(2r,3r,4s,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-octahydroazuleno[4,5-b]furan-2-one

Description

Ixerin D belongs to the class of organic compounds known as guaianolides and derivatives. These 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. (3as,6r,6as,8r,9ar,9br)-6-hydroxy-6-methyl-3,9-dimethylidene-8-{[(2r,3r,4s,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-octahydroazuleno[4,5-b]furan-2-one is found in Ixeridium dentatum, Ixeris chinensis, Ixeris repens, Ixeris tamagawaensis, Taraxacum erythrospermum and Taraxacum officinale. It was first documented in 2006 (PMID: 17146959). Based on a literature review a small amount of articles have been published on Ixerin D (PMID: 31928353) (PMID: 31731238) (PMID: 25509293).
