Dehydroabietylamine (Leelamine) is a diterpene compound, derivatives from gum rosin. After a series of distillation process, the residual liquid of turpentine oil is steamed out. Then filter the residual liquid at 210℃ or so and cool and crystallize to get the finished product.
Dehydroabietylamine has a weak affinity for the cannabinoid receptors CB1 and CB2, as well as being an inhibitor of pyruvate dehydrogenase kinase. Optically active leelamine is also used as a chiral resolving agent for carboxylic acids.
