The component composition of essential oils produced by steam distillation from flower heads, leaves, and stems of Salvia anatolica (Lamiaceae), a recently described new species endemic from Turkey, was studied by GC/FID and GC/MS. A total of 127 volatile
components representing 96% of the oil was identified in essential oil from flower heads and leaves. It was found that the
principal oil components of flower heads and leaves were α-pinene (10.9%), β-pinene (6.7%), α-copaene (6.3%), heptacosane (6.2%), and hexadecanoic acid (5.0%). A total of 109 volatile compounds representing 87.9% of
the oil was characterized in essential oil isolated from stems. The principal oil components of stems were identified as hexadecanoic
acid (27.2%), tetradecanoic acid (15.2%), dodecanoic acid (5.5%), and α-copaene (5.0%).

by GC and GC-MS apparatus. Fourteen compounds representing 98.8% of the oil were identified. Among them N-methylisatin (30%),
α-pinene (25%), sabinene (12.3%), and 2-hydroxyacetophenone (11.2%) were the major constituents of the oil, which was obtained
in 0.1% yield.

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.

A new pentacyclic triterpenoid, urs-12-en-29α-oic acid-3β-ol (1), was obtained from the ethanol extract of Chinese herb Oldenlandia cantonensis How. The structure was elucidated by spectroscopy methods, including nuclear magnetic resonance (NMR) (1D and 2D), infrared
spectroscopy (IR), and mass spectrometry (MS). 1 exhibited significant inhibitory activity against the human DNA topoisomerase
I (hTopo I), the cancer cell lines BEL-7402 and MCG-803, with the IC50 values 12.0, 6.5, and 8.0 μg/mL, respectively. The volatile oil, the fraction of petroleum ether: EtOAc = 20:1 (V/V) on Si gel chromatography, was also quantitatively analyzed by gas chromatography mass spectrometry (GC-MS). As a result,
60 compounds were identified. Among them, the long chain aliphatics, terpenes and steroids, as the representative structure
type, were found with percentages of 36.16%, 6.42% and 9.28%, respectively.

The fruit oils of Athamanta turbith ssp. hungarica and Athamanta turbith ssp. haynaldii were obtained by Soxhlet extraction using petroleum ether. The fatty acid composition of oils was determined by GC in the
methyl ester form. Considering the composition and content of fatty acids, the examined oils were very similar. Petroselinic
acid was the principal one (45.6 and 46.2%, respectively), followed by a significant amount of linoleic acid (26.9 and 29.1%,
respectively). In both oils, myristic, pentadecanoic, palmitic, palmitoleic, stearic, petroselinic, oleic, linoleic, α-linolenic,
arachidic, and behenic acid were identified. Lignoceric acid was detected only in A. turbith ssp. hungarica oil.

The root of Carlina acanthifolia All. (Asteraceae) contained 1.0% of essential oil (expressed in g per 100 g of dried plant material). Using GC and GC/MS,
nine components were identified (100% of total oil). The structure of benzyl 2-furylacetylene (carlina oxide), which is the
principal component of the oil (91.5%), was spectrometrically identified.

Inclusion complex between the essential oil
of Mentha x villosa Hudson and β-cyclodextrin,
with a 1:9 mass/mass oil–β-cyclodextrin ratio was prepared by co-precipitation
and kneading methods in a hydroethanolic medium. The GC/MS analysis showed
a total volatile content of 99.5% in the Mentha x
villosa oil. The characterization of the complex involved the analysis
of the original essential oil, the surface and the total extracted oils. Among
28 detected compounds in the original essential oil, 13 are monoterpenes and
10 sesquiterpenes, furthermore, piperitenone-oxide is the major component
(35.4%). 12 compounds were totally and 11 partially complexed, 3 have been
adsorbed only on the surface of the β-CD and 2 have not been detected
neither in the surface oil nor in the complexed oil. A 13.6% encapsulation
efficiency was observed, while the total oil and volatiles retention was 15
and 77%, respectively. Non-parametric statistic analysis of the data showed
that the profile of the volatiles were not significantly different comparing
the original oil and the complexed oil (p>0.04).
The results of thermogravimetry-mass spectrometry and XRD analysis have proven
the inclusion complex formation between the essential oil and cyclodextrin. 相似文献

Essential oil composition of Plectranthus asirensis grown in Saudi Arabia was chemically analysed for the first time by various gas chromatography techniques (GC–MS, GC–FID, Co–GC, LRI determination and database and literature searches) using two different stationary phase columns (polar and nonpolar). This analysis led to the characterisation of a total of 124 components representing 98.5% of the total oil composition. The results revealed that P. asirensis oil was mainly dominated by monoterpenoids (90.7%) in which most representative constituents were thymol (66.0 ± 0.36%), γ-terpinene (14.0 ± 0.18%), p-cymene (5.2 ± 0.06%) and β-caryophyllene (3.0 ± 0.03%). It is worth mentioning here that this is the first report on the phytochemical constituents of P. asirensis. 相似文献

Inclusion complexation with cyclodextrins is an effective way to improve stability and turn liquid materials into re-dispersible and easy-to-handle powders. In the present work, the complexation of L. gracilis essential oil, already recognized as a potent larvicide material, with hydroxylpropyl-β-cyclodextrin was performed using slurry and paste procedures and the complexes obtained were evaluated. The gas chromatography coupled to mass spectrometry (GC/MS) analysis showed a total volatile content of 99.24% in the L. gracilis oil. The characterization of the complex involved the analysis of the original essential oil, the surface, and the total extracted oils. The major components in L. gracilis essential oil were identified as carvacrol (23.52%), p-cymene (15.82%), γ-terpinene (14.17%), and thymol (7.27%). GC/MS results showed significant differences between the original oil, the slurry, and paste complexation. Thermal characterization indicates the occurrence of complexation, mainly in paste complexes, which presents a TG–DTA peak at 230–275 °C, probably related to oil loss. 相似文献

composition of the essential oils in the two species have been compared.O. vulgare ssp.hirtum oil was found to contain carvacrol (76.4%), γ-terpinene (6.6%), thymol (0.23%), andp-cymene (4.7%) as the main constituents whereas the major compounds inO. vulgare ssp.vulgare oil werep-cymene (22.3%), caryophyllene oxide (10.2%), sabinene (7.9%), γ-terpinene (5.1%), thymol (0.34%), and spathulenol (4.8%).
The stability of content and composition of the oils during the flowering period (economically beneficial period) were observed.
The effect of long-term storage on the composition of the oil was also investigated for both the crude and distilled oil ofOriganum vulgare ssp.vulgare.

Analyses of the essential oils of Bunium elegans (Fenzl) Freyn and B. caroides (Boiss.) Hausskn. ex Bornm., using GC, GC/MS, and13 C-NMR spectroscopy resulted in identification of their chemical constituents. The oils of both species contain mainly the
sesquiterpene hydrocarbons germacrene-D and E-caryophyllene, which amounted to 24.1% and 38% for B. elegans and 22.1% and 26.6% for B. caroides respectively. The oil of B. caroides contained the monoterpenes α-pinene and Z-β-ocimene in 4.1 and 5.9% respectively, while traces of monoterpenes were detected
for B. elegans. On the other hand, in B. caroides the phenylpropanoid derivatives asaricin (7.5%) and dillapiole (10.2%) were among the major constituents.
