| Common Name | (R)-Mahanine |
|---|
| Description | (R)-Mahanine, also known as bisisomahanine, belongs to the class of organic compounds known as carbazoles. Carbazoles are compounds containing a three ring system containing a pyrrole ring fused on either side to a benzene ring (R)-Mahanine has been detected, but not quantified in, herbs and spices. This could make (R)-mahanine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (R)-Mahanine. |
