| Rotundine A | C15H21NO | |
| Rotundine B | C15H23NO4 | Rotundine B belongs to the class of organic compounds known as methylpyridines. These are organic compounds containing a pyridine ring substituted at one or more positions by a methyl group. Rotundine B is a very strong basic compound (based on its pKa). Outside of the human body, rotundine b has been detected, but not quantified in, root vegetables. This could make rotundine b a potential biomarker for the consumption of these foods. |
