Abstract
Juniper seed oil extracted by steam distillation has been a useful material as a medicine, insect repellant, and flavorant for alcoholic beverages. As the result of juniper seed oil analysis, the acid value, saponification value, unsaponification value phosphorus contents, and refractive index were 91.04, 85.15, 15.52, 11.04 ppm, 1.47, respectively The content of neutral lipids, glycolipids and phospholipids were 85.4%, 12.2% and 2.4%, respectively. From the fatty acids analysis, the major fatty acids from the juniperseed harvested in August were lauric acid (31.9% ), palmitic acid (28.0% ), stearic acid (9.9%), and oleic acid (8.5%) . However, maturated seed oil harvested in October mainly consists of linoleic acid (47.6%), linolenic acid (17.6%), oleic acid (16.1%), and palmitic acid (11.9%). Upon these analyses, fatty acids composition of juniper seed oil depends on the seed maturation. According to volatile compounds analyses of essential oil extracted using steam distillation method and SPME, the major compounds were $\beta$-myrcene, $\alpha$-pinene, $\beta$-farnescene, $\beta$-cubebene, limonene, trans-caryo-phyllene, $\alpha$-terpinolene, camphene, sabinene, and $\beta$-pinene.
