 Dried seed cones, commonly known as "juniper berries", are used as spice in European kitchen, especially for venison and sauerkraut (sour cabbage). There are juniper-flavored distilled beverages like [[http://en.wikipedia.org/wiki/Gin|gin]] and [[http://en.wikipedia.org/wiki/Wacholder|wacholder]].

+"**Juniper berry oil** is stated to possess a wide spectrum of pharmacological activities and its monographs are
 included in some National Pharmacopoeias. The antibacterial and antifungal activity of the oil was reported
 by some authors. In our study we estimated the antibacterial and antifungal activity of three different juniper
 berry oils and their main components. All the micro-organisms used in this experiment were isolated from
 patients of Regional Hospital of Gdansk and some of them showed resistance against commonly used antibiotics. Only one of the oils (labelled A) revealed good antimicrobial properties. None of the single oil components was a stronger antibacterial and antifungal inhibitor than the oil A itself. Our data suggest that the antimicrobial activity of juniper oil A is the result of either the specific composition of the oil A (highest concentration of α-pinene, p-cymene and β-pinene) or activity of a single non-identified compound. The presence of an adulterant in the oil was excluded." \\

 "The analysis of the essential oil from berries of J.communis L. subsp.alpina by CC, GC-RI, GC-MS and 13C-NMR allowed the identification of 65 compounds which represented 95.3% of the whole oil. Monoterpene hydrocarbons constituted the main group of compounds (82.0%), especially limonene (49.3%) and α-pinene (22.1%). Among the sesquiterpenes (7.9%), germacrene-D (2.0%), δ-cadinene (1.2%) and β-elemene (1.1%) were the major constituents. Oxygenated monoterpenes (5.3%) were largely represented by α-terpinyl acetate while the other compounds were present at very low content, less than 0.4%." \\

 "The essential oil of juniper berry has diuretic properties, gastrointestinal irritant and antiseptic properties. The diuretic action of juniper is primarily due to its essential oil, which contains terpinen-4-ol. The content of essential oil in the berry ranges from 0.5 to 2.5% (V/m), and its main compounds are terpen hydrocarbons such as α- and β-pinene, myrcene, sabinene, thujone, limonene, etc. Oil also contains sesquiterpene hydrocarbons (caryophyllene, cadinene, elemene) and terpen alcohols (terpinen-4-ol)...\\

+The main monoterpenoids (representing 70% of the sample’s volatile fraction) detected by SPME in the
+headspace of juniper berries were terpinen-4-ol (22.5-30.6%), p-cymene (7.58-13.5%), β-myrcene (10.6-11.3%), ɣ-terpinene (3.0-10.1%), α-pinene (8.5-13.4%), limonene (4.4-5.9%) and α-terpinene (1.3-4.2%). Main sequiterpenoid was δ-cadinene (3.9-5.9%). Cis-rose oxide was found only by SPME (0.11-0.18%) but not not in SDE. \\
