“…Another extraction technique frequently reported in the literature is a steam distillation process where fresh leaf material is steam-extracted into hexane or pentane (Muzika et al 1990, Riddle et al 1996. The steam distillation process can last as little as 90 minutes (Hachey and Simard 1987) or as long as 8 hours (Mu&a et al 1990). A survey of the literature shows that both extraction techniques are used in about equal frequency across a wide array of species (Hachey and Simard 1987, Gilmore 1977, Chang and Hanover 1991, Muzika et al 1989.…”

Concentration and composition of monoterpenoids in plant tissue affects a variety of environmental and ecological issues such as plant defenses, plant classification, and phytotoxicity. Developing the techniques for extracting and estimating the concentration and composition of monoterpenoids must be speciesspecific because monoterpenoid storage location varies between species. Ashe juniper f,Juniperus ashei Buchholz) and redberry juniper t,J. pinchotii Sudw) are 2 co-occurring species which differ in palatability and preference. The objective of this study was to determine which of 2 common extraction techniques provided the best estimate of the concentration and composition of monoterpenoids in mature plant tissue. Two extraction techniques were tested by soaking crushed juniper needles in hexane solvent for 6, 12, 18 and 24 hours or by steam distilling samples for 2,4,6, or 8 hours. The extracts were analyzed by using 2 different analytical columns in separate gas chromatographs. The hexane solvent soak, regardless of time in the solvent, yielded a lower total concentration and a decreased compositional diversity of monoterpenoids compared to the steam distillation technique. An g-hour steam distillation yielded the greatest concentration and composition of monoterpenoids. Both types of analytical columns resulted in similar estimates of monoterpenoid concentrations and composition.

“…These species also contain carene and limonene in quite high amounts. 7,8 Appreciable amounts of limonene/β-phellandrene and bornyl acetate, but little carene, were found in needle extracts of P. omorika (native), P. orientalis (arboretum specimen) and P. jezoensis (cultured). 20 In needles of oriental spruce, αand β-pinene, camphene, β-myrcene, α-terpinolene, borneol, terpineols, βcaryophyllene, germacrene and cadinol isomers are other significant compounds.…”

Volatile needle and wood extracts of oriental spruce obtained from trees grown naturally in eastern Black Sea regions and in an cultivated stand near Istanbul were analysed by GC-MS. Despite considerable differences in both tree-to-tree and natural-to-cultivated aspects, the needle and wood extracts exhibit characteristic compounds, which might be of chemotaxonomic interest. The monoterpenes δ-3-carene, limonene and bornyl acetate dominate in the needles, whereas the appreciable amounts of labdadienol isomers and high content of diterpenoids characterize the wood extracts.
