Juniper essential oil characteristics determined

SHERIDAN, WYThroughout the western United States, Canada, and Mexico, Rocky Mountain juniper (Juniperus scopulorum Sarg.) is known for its pleasant fragrance and valuable wood. The juniper's woodhighly valued for its durability, rich color, and pleasant aromais popular for use as interior paneling, furniture, and fence posts. For centuries, the leaves and berries of Rocky Mountain juniper, which contain strongly aromatic essential oil, have been used extensively by native people of North America to treat a number of medical conditions. A recent study evaluated several aspects of variations in essential oil composition and content of the popular tree.

Valtcho D. Zheljazkov and Ekaterina Jeliazkova from the University of Wyoming's Sheridan Research and Extension Center, along with Tess Astatkie of Canada's Dalhousie University, published their research results in the July 2013 issue of HortScience. "We thought that the essential oil content and composition may be different in male and in female trees and also may be affected with seasonal changes throughout the year," Zheljazkov explained. The team evaluated one male and one female Rocky Mountain juniper tree over the course of 1 year. They found that the concentration of essential oil in fresh leaves varied from 0.335% to 0.799%. The team also determined that, at most of the sampling points, the oil content in the biomass of the male tree was greater than that in the biomass of the female tree.

"This study demonstrated that there are seasonal differences in essential oil content and composition within male or female trees. Also, at any given sampling point, the concentration of some oil constituents may be higher in the oil from the female trees, whereas the concentration of other oil constituents may be high in the oil of male trees," Zheljazkov said.
