Plantago arenaria

The same group (61) has also investigated the formation of boschniakine (121) in Plantago arenaria. Alkalinization of the plant extract with ammonia increased the alkaloid level compared with the use of NaHC03, and the content of both boschniakine (121) and methyl boschniakinate (24) were increased. In the former case this was traced to the iridoid plantarenaloside... 

Seeds of the Plantago arenaria plant yield an alkaloid, 4 called arenaine (133) whose structure was assigned by Rabaron et al.9S mainly on the basis of nC nuclear magnetic spectroscopy.

A new alkaloid, methyl boschniakinate (24), was isolated from the two Plantago species, P. arenaria and P. psyllium (61). The alkaloid was charac-...
