Chemical Information
FooDB NameCoclaurine
DescriptionCoclaurine, also known as (r,s)-coclaurine or machiline, is a member of the class of compounds known as benzylisoquinolines. Benzylisoquinolines are organic compounds containing an isoquinoline to which a benzyl group is attached. Coclaurine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Coclaurine can be found in custard apple and soursop, which makes coclaurine a potential biomarker for the consumption of these food products. Coclaurine is a nicotinic acetylcholine receptor antagonist which has been isolated from a variety of plant sources including Nelumbo nucifera, Sarcopetalum harveyanum, Ocotea duckei, and others. It belongs to the class of tetrahydroisoquinoline alkaloids. Dimerization of coclaurine leads to the biscoclaurine alkaloids such as cepharanthine .
