Abstract
Combinations of silver nitrate column, gel permeation and gas liquid chromatography were used to isolate 8,15-pimaradien-18-oic, 8,15-isopimaradien-18-oic and the secodehydroabietic, 2α-[2′(m-isopropylphenyl)ethyl]1β,3α-dimethylcyclohexanecarboxylic acids as their methyl esters from a fraction of distilled tall oil.
