Rosins are natural compounds derived from pine tree resin. They have many uses in industry, including paints, adhesives and soldering fluxes. In this work HPLC and CE was used to characterise rosin samples which are composed of 90% acidic compounds and 10% neutral compounds including aldehydes and terpenes. Cyclodextrin-modified CE methods were developed for the separation of acids, terpenes and aldehyde groups. The presence and concentration of acids in several rosin samples was investigated.
