Fruits ofPeucedanum oreoselinum (L.) Moench, were collected at three sites in 1995–1998 and contained 1.5–5.0% essential oil. Analyses were performed using
GLC and GC-MS. The main component of the essential oil is limonene (44.1–82.4%). The majority of examined samples contained
more limonene than has been reported in the literature. Only in sunny locations do plants synthesize significant quantities
of γ-terpinene (12.2–17.5%) and β-pinene (8.5–14.5%). Small quantities of α-pinene are present in all studied samples of essential
oil (4.0–8.3%). Monoterpenes comprise 97.1–98.6% of the essential oil. The remainder consists of sesquiterpenes.

Aerial parts of Sideritis cilicica Boiss. & Bal. and Sideritis bilgerana P.H. Davis (Lamiaceae) were hydrodistilled to obtain essential oils that were then analyzed by GC and GC/MS. β-Pinene (39%),
α-pinene (28%), and β-phellandrene (20%) were the main components in the oil of S. cilicica, while β-pinene (48%), and α-pinene (32%) were the major constituents in the oil of S. bilgerana. The antimicrobial activities of the oils were evaluated by using the microdilution broth method. Both of the oils showed
good inhibitory effects on C. albicans.

Steam distilled oil from the shoots, separated leaves, and stem, as well as from the flower of laurel (Laurus nobilis), grown in Montenegro, were analyzed by GC and GC/MS. The yield of essential oil was as follow: 1.4% in young shoots, 1.5%
in the separated leaves, and 0.7% in separated stems. The main constituents of all investigated oils were 1,8-cineole, methyleugenol,
and α-terpinyl acetate. Besides, α-pinene, β-pinene, sabinene, and linalool were also present. It was interesting and important for commercial samples of laurel essential
oil that there was no significant difference among the essential oil obtained from young shoots and those obtained from leaves
and stem. The main constituents of the flower oil were 1,8-cineole (15.7%), β-caryophyllene (9.5%), γ-muurolene (7.1%), α-terpinyl acetate (6.5%), and methyleugenol (3.9%).

The chemical composition of Pinus silvestris essential oil from contaminated areas was studied. An apparent effect of radionuclides and toxic elements on the biosynthesis
of terpenoids in common pine essential oil was found. Increasing contamination apparently increased the content of sesquiterpenes
and O-containing substances and decreased the content of monoterpenes in the essential oil. The contents of α-pinene, camphene,
and limonene increased and those of 3-carene, terpinolene, and β-pinene decreased in the monoterpene fraction.

The results are reported of the interaction of the trans,trans-germacradienolide hanphyllin with m-chloroperbenzoic acid and
with 50% sulfuric acid. This leads to a cyclization reaction with the formation of eudesmanolides: 1β-hydroxy-3-oxo-1,4,5,7α(H),6β(H)-eudesm-11(13)-en-6,12-olide,
ridentin B, and 3β-hydroxy-5,7α(H),6β(H)-eudesma-4(15),11(13)-dien-6,12-olide; and also products of the opening of the lactone
ring as a consequence of transesterification. The structures of the compounds obtained are discussed on the basis of spectral
results (IR, PMR, and mass spectra) and of x-ray structural analysis.

1. The following compounds have been isolated by gas-liquid chromatography from the essential oil ofArtemisia rutifolia Steph. ex Spreng. growing in the Mongolian People's Republic and have been identified by their IR spectra: 1,8-cineole (35%),
α-thujone andβ-thujone (11%), (+)-camphor (18%), (−)-α-terpineol (5%), and (−)-terpinen-4-ol (7%). By analytical gas chromatography α-pinene,β-pinene, camphene, limonene,β-phellandrene, and p-cymene have been identified in the hydrocarbon fraction.
It has been shown that apart from compounds of a terpene nature the oil contains 4-phenylbutan-2-one, (±)-4-phenyl-butan-2-ol,
and (±)-4-phenylbut-2-yl acetate. This is the first time that (±)-4-phenylbutan-2-ol and its acetate has been found in plant

Comparative thermolysis of β-and α-pinenes in supercritical ethanol: the reaction characterization and enantiomeric ratios of products 总被引:2,自引:0,他引:2

The thermolysis of β-pinene and the co-thermolysis of an equimolar mixture of β-and α-pinenes in supercritical ethanol were
carried out. The reaction of β-pinene affords β-myrcene as the major product (>70%). Considerable differences in the temperature
dependence of the reaction rate were revealed for the transformations of β-pinene into β-myrcene and of α-pinene into limonene.
The pre-exponential factors and the activation energies were calculated. The enantiomeric ratios of the thermolysis products
of β-and α-pinenes and limonene were estimated. The starting monoterpenes do not undergo racemization during thermolysis.
The thermolysis of enantiomerically pure α-pinene affords racemic (±)-limonene, whereas (−)-β-pinene gives (−)-limonene. The
enantiomeric ratio in the latter remains equal to the enantiomeric purity of the starting β-pinene.

The kinetics and thermodynamics of the liquid phase isomerization of an α- and β-pinene mixture on a Pd/C catalyst were studied.
The effects of pinene concentration, catalyst particle size, stirring rate, reaction temperature (293–423 K) and hydrogen
pressure (0.5–11 bar) on the rate of α- and β-pinene isomerization were investigated. The reaction rate of the α-pinene isomerization
has the first order with respect to the α-pinene concentration and 0.5 order with respect to the hydrogen pressure. The thermodynamic
parameters of the isomerization (Gibbs energy, reaction enthalpy and reaction entropy) and the equilibrium ratio of pinenes
under the conditions studied were determined. The general scheme of the reaction mechanism of α- and β-pinene isomerization
over the Pd/C catalyst was proposed. 相似文献
