Hydrodistilled volatile oils from crushed dry stems, leaves, and roots of Prangos latiloba Korov. (Umbelliferae) growing wild in Sabzevar (Iran) were analyzed by GC and GC/MS. Eight compounds constituting 84.72% of stem oil, twelve compounds
constituting 95.39% of leaf oil, and nine compounds constituting 88.73% of root oil have been identified. The main components
of stem oil were γ-cadinene (30.39%), α-pinene (25.47%), and sabinene (12.55%). The main components of leaf oil were germacrene
D (27.79%), α-pinene (17.81%), β-caryophyllene (12.75%), and β-pinene (11.23%). The main components of root oil were spathulenol
(29.5%), 1,8-cineol (19.42%), p-cymene (17.03%), and α-bisabolol (15.33%).

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%).

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

Use of solid-phase microextraction as a sampling technique for the characterization of volatile compounds emitted from Chinese daffodil flowers 总被引:1,自引:0,他引:1
Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) has been applied
to the determination of volatile compounds emitted from living daffodil flowers. The SPME conditions were optimized and applied
to headspace extraction of the volatile compounds. The volatile compounds adsorbed on the fiber were desorbed and analyzed
by GC-MS. We identified 27 compounds in the flower emission, which mainly included acetic acid phenethyl ester (31.68%), E-ocimene (17.15%), acetic acid benzyl ester (11.53%), neo-allo-ocimene (6.94%), allo-ocimene(5.34%), α-linalool (5.26%), 1,8-cineole(3.70%), benzenepropyl acetate (1.98%), and 3-methyl-2-buten-1-ol acetate(1.88%).
The volatile compounds emitted by the flower excised from the daffodil were also analyzed by the present method, and the results
showed that n-pentadecane, n-hexadecane, n-octadecane, and acetic acid phenethyl ester might be biomarker compounds of living daffodil flowers. To our knowledge, this
is the first report on the volatile compounds emitted from Chinese daffodil flowers.

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.

compounds (93.3%) in the hydrodistillate oil, 55 compounds (94.2%) in the steam distillate oil, and 34 compounds (98.4%) in
the hydrolate were identified. The major compounds in the hydrodistillate oil were α-pinene (12.1%), methyl geranate (11.2%),
β-ocimene (8.6%), and limonene (7.2%). α-Pinene (15%), methyl geranate (14.5%), limonene (11.2%), and β-ocimene (8.4%) were
the most abundant components in the steam distillate oil. The percentages of geraniol (13%), trans-verbenol (11.6%), and terpinen-4-ol
(11.2%) were more than other constituents in the hydrolate.

The composition of essential oil from Artemisia glauca (Asteraceae) growing in southern Siberia was studied. More than 60 oil components consisting of 99.0–99.7% of the total volatile
components were identified by GC—MS by comparison of full mass spectra and retention times. The main components of the essential
oil were acetylene derivatives of capillene (11–60%) and benzyldiacetylene (1–31%). Other acetylene derivatives such as capillin,
(E)-hex-4-en-2-ynylbenzene, 1-(4-methoxyphenyl)-2,4-pentadiyne, and capillarin were also identified in the oil.

A simple, quick and nontoxic analytical method for the simultaneous determination of five synthetic antioxidants [t-butyl-4-hydroxyanisole (BHA), 2,6-di-t-butyl-hydroxytoluene (BHT), t-butyl hydroquinone (TBHQ), ethoxyquin (EQ) and 2,6-di-tert-butyl-4-hydroxymethyl-phenol (Ionox 100)] in edible vegetable
oil has been developed. The analytes were extracted by ethanol, then separated and detected by GC–MS. Extraction conditions
such as volume of ethanol required, mixing time and number of extractions were investigated and optimized by an orthogonal
array experimental design. The five compounds behaved linearly in the 0.100∼20.0 mg/L concentration range, and the limits
of detection (LOD) for BHA, BHT, TBHQ, EQ and Ionox-100 were 1.00, 0.92, 11.5, 0.83 and 1.39 μg/L, respectively. The recoveries
at the tested concentrations of 1.00, 20.0 and 100 mg/kg were 75.6∼123%, with coefficients of variation <10.0%. The proposed
procedure was successfully applied to the simultaneous analysis of the five antioxidants in soybean oil, tea oil, edible blended
oil, rap oil, peanut oil, peanut blended oil and sesame oil samples purchased from local supermarkets. 相似文献

Eugenol is the main volatile compound extracted oil from clove bud, Syzygium aromaticum L., and used in traditional medicine, as a bactericide, fungicide, anesthetic, and others. Its extraction was performed using
hydrodistillation which is the most common extraction technique. Its components and thermal behavior were evaluated using
gas chromatography (GC) and differential scanning calorimetry (DSC), which provide a better characterization of these natural
compounds. This extracted product was compared to the standard eugenol results. The GC results suggested ~90% eugenol was
found in the total extracted oil, and some of its boiling characteristics were 270.1 °C for peak temperature and 244.1 J g−1 for the enthalpy variation.
