LOURIZÁN EXPLORES THE INTEREST OF PHARMACEUTICAL INDUSTRY IN PINE RESIN
Volatile compounds of the pine resin have an unexploited potential. Traditional resining by means of bark pike obtains cade with high percentage of solids—colophony—and with a low percentage of turpentine—the volatile component. That resin is adapted to the traditional applications of the resining industry, focused on the colophony products. However, if a higher quality resin was obtained (with more percentage of turpentine), new uses could be aimed. New uses, such as the pharmaceutical, with greater added value.
The Lourizán Forestry Research Centre has been working a couple of years on this hipothesis. Lourizán studies the adaptation in Galicia of the borehole method in order to obtain resin with greater percentage of the volatile portion. The borehole method used by the centre consists in practicing two holes at the trunk base where polyurethane containers are connected in order to collect the resin.
The Lourizán Forestry Research Centre got in contact with pharmaceutical companies in order to evaluate the interest in the resin obatined by the borehole method. “It’s a resin with double the conventional level of turpentine. In addition, it has a greater percentage of alpha-pinene, from which verbenone is obtained”—explains Enrique Martínez, centre manager.
