“…In conifers, essential oils are usually mixed with higher terpenes, and thus are referred to as oleoresins. They have been used as environmental and chemotaxonomic markers in many conifer species, with the latter ranging from family to infra-specific level [13][14][15][16][17][18][19][20]. Unlike some members of the Cupressaceae family, oleoresins in Pinus are stored in resin ducts located in leaves and branches, where they are used as protection against predatory insects [21].…”

Many studies show the influence of the environment on terpene composition, but not many of them deal with the terpene composition variability in correlation with environmental factors in Pinus. We chose two endemic species-P. heldreichii Christ. (Bosnian pine) and P. peuce Griseb. (Macedonian pine)-two relict and (sub)endemic species of the Balkan peninsula. They mainly form pure stands but can appear in mixed populations, most commonly with each other. These species belong to different subgenera and thus differ greatly, especially in needle anatomy. α-pinene, limonene and germacrene D predominated in Bosnian pine leaf oleoresins, while Macedonian pine oleoresin contained high amounts of α-pinene. Furthermore, there were three chemotypes present in Bosnian, and only one in Macedonian pine. Oleoresins of Bosnian pine did not show correlation with climate, however, its composition changed in response to geological substrate type. Macedonian pine oleoresin showed a high correlation with the climate but changed only a little in response to geological substrate type. The oleoresin profiles showed strong species-dependent composition and variability. However, since each species expressed different responses to tested environmental conditions, it is important to take into consideration these variables when analyzing natural populations of the species.

“…Conifer terpenes have been used as ecological and chemotaxonomic markers for a long time, first at genus level (Pinus [10] [11], Picea [12] [13], other genera [14] [15], etc. ), and later at family level [16] [17], etc.…”

Terpenes are often used as ecological and chemotaxonomic markers of plant species, as well as for estimation of geographic variability. Essential oils of relic and Balkan endemic/subendemic conifers, Picea omorika, Pinus heldreichii, and P. peuce, in central part of Balkan Peninsula (Serbia and Montenegro), on the level of terpene classes and common terpene compounds were investigated. In finding terpene combinations, which could show the best diversity between species and their natural populations, several statistical methods were applied. Apart from the content of different terpene classes (P. omorika has the most abundant O-containing monoterpenes and sesquiterpenes; P. heldreichii and P. peuce have the largest abundance of sesquiterpene and monoterpene hydrocarbons, resp.), the species are clearly separated according to terpene profile with 22 common compounds. But, divergences in their populations were established only in combination of several compounds (specific for each species), and they were found to be the results of geomorphologic, climatic, and genetic factors. We found similarities between investigated species and some taxa from literature with respect to terpene composition, possibly due to hybridization and phylogenetic relations. Obtained results are also important regarding to chemotaxonomy, biogeography, phylogeny, and evolution of these taxa.

Aus dem Gummiharz von Commiphora mukul Ergl. (Burseraceae) (indisches "Cuggu1"-Harz) wurden die monocyclischen Diterpene &Camphoren (2) und Cembren (4) isoliert. Fur einen Diterpen-Alkohol "AUylcembrol" wird die Struktur des 2-Hydr0xy48.12-trimethy1-impropyl-cyclodecatrien~(3.7.11) (6) vorgeschlagen. 6 wurde auch in den getrockneten oberirdischen Teilen von C.mukul nachgewiesen. Monocyclic Diterpenes From Indian Gum Gugul (Commiphcnr mukul)The monocyclic diterpenoids (Y-camphoreno (2) and cembrene (4) were isolated from gum resin of Commiphora mukul Engl. (Burseraceae) ("Indian gum gugul"). For the diterpene alcohol "allylcembrol" the structure of 2-hydroxy-4.8.12-trimethyl-isopropy1-3.7.ll-cyclodecatriene (6) is proposed. 6 was isolated from the dried overground parts of C. mukul as well.
