| Description | Sudachitin belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. Thus, sudachitin is considered to be a flavonoid. Sudachitin has been detected, but not quantified in, a few different foods, such as citrus, mandarin orange (clementine, tangerine), and peppermints (Mentha X piperita). This could make sudachitin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Sudachitin. |
