Metabolite Identification
Common Name17-O-acetylnorajmaline
Description17-o-acetylnorajmaline is a member of the class of compounds known as ajmaline-sarpagine alkaloids. Ajmaline-sarpagine alkaloids are organic compounds containing either of the ajmalan, sarpagan skeleton, or derivative thereof. The Sarpagine (Akuammidine) group, based on the sarpagan nucleus, arises from bond formation between C-16 and C-5 of the corynantheine precursor. Ajmaline alkaloids are based on a 17,19-secoyohimban skeleton (oxayohimban) which is invariably present as an ether. 17-o-acetylnorajmaline is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 17-o-acetylnorajmaline can be found in a number of food items such as black chokeberry, sapodilla, common pea, and cardamom, which makes 17-o-acetylnorajmaline a potential biomarker for the consumption of these food products.
