Abstract

Commercial samples of Tolu Balsam have been analysed by gas–liquid chromatography and the aromatic acid and ester content compared with appropriate BPC standards. Modern samples show an increase in benzoic acid content, a decreased cinnamic acid content and the absence of benzyl cinnamate. Some samples were found to contain additional unreported constituents, namely, cinnamaldehyde and benzyl alcohol.
