Metabolite Identification
Common NameSantal
DescriptionSantal belongs to the class of organic compounds known as 7-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C7 atom of the isoflavone backbone. Thus, santal is considered to be a flavonoid. Santal has been detected, but not quantified in, green vegetables. This could make santal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Santal.
