DescriptionN-Methyl-14-O-demethylepiporphyroxine, also known as glycerol tri-a-eleostearate or tri-a-eleostearoylglycerol, belongs to the class of organic compounds known as rhoeadine alkaloids. These are alkaloids with a structure based on rhoeadine. They usually contain a benzazepine system fused with a six-membered hemiacetal or acetal. Based on a literature review very few articles have been published on N-Methyl-14-O-demethylepiporphyroxine.
