piperidine Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor de ...

. Alkaloids with a piperidine building block are widespread and are usually further subdivided according to their occurrence and biogenetic origin. The most important representative of piperidine alkaloids is piperine, which is responsible for the pungent taste of pepper. The piperidine alkaloids also include the sedum alkaloids (e.g. sedamine), pelletierine, the lobelia alkaloids (e.g.
