A new trans-4-methoxy derivative of pipecolic acid was isolated from the tropical legume, Inga paterno. Structure elucidation and conformational analysis were ascertained using a variety of NMR techniques; A hitherto unknown keto fatty acid has been isolated from Gardenia lucida seed oil. It has been characterized as 7-keto-octadec-cis-11-enoic acid based on spectrometry and chemical degradations.
