Abstract
The residue from tall oil distillation, known as tall oil pitch (TOP), was investigated by GC/MS analysis. Several separation techniques such as preparative TLC and extractions from solutions of different pH were applied. Apart from about 4% distilled free acids (fatty and diterpenoid) and 5% steroids (sitosterol and sitostadiene) two new fatty acids C-26 and C-28 could be detected. About 1% of lignin like material could be isolated after continuous extraction with chloroform.
