Metabolite Identification
Common NameSemilicoisoflavone B
DescriptionSemilicoisoflavone B belongs to the class of organic compounds known as pyranoisoflavonoids. These are isoflavonoids that contain a pyran ring fused to either of the A, B, or C ring of the isoflavonoid skeleton. Thus, semilicoisoflavone b is considered to be a flavonoid. Semilicoisoflavone B has been detected, but not quantified in, root vegetables. This could make semilicoisoflavone b a potential biomarker for the consumption of these foods. Semilicoisoflavone B is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Semilicoisoflavone B.
