The total fractions of choline esters have been isolated from different parts of Sinapis alba. 4-Hydroxybenzoylcholine has been identified and found to be one of the quantitatively dominating choline esters in seed extracts of S. alba.The identity of the new natural product has been confirmed by comparison with synthetic reference compounds.Several different choline esters are present in this plant but in extracts of seedlings, leaves, and inflorescences they are not so quantitatively dominating as in seeds.The modified ion-exchange technique applied appeared to be an ef ficient tool in the isolation and separation of choline esters and amines from other types of phenolic plant constituents.Key Word Index - Sinapis alba; Cruciferae; choline esters; sinapine; 4-hydroxy-3,5-dimethoxycinnamoylcholine; 4-hydroxybenzoylcholine; 3-hydroxybenzoylcholine; 2-hydroxybenzoylcholine; 4-hydroxy-3-methoxybenzoylcholine; 3-hydroxy-4-methoxybenzoylcholine; phenols; choline ester synthesis.
