In recent years, many investigations on the anthocyanins of the fresh Lycium ruthenicum Murray fruits have been reported; while few studies about dried fruits have been published. In this study, chemical profile of dried fruits was illustrated by a high-performance liquid chromatography–tandem mass spectrometry method, which provided evidence for the certain identification of the main anthocyanins. Among these compounds, nine of them were selected as marker compounds for the semiquantitative evaluation, using a simple and reliable method by high-performance liquid chromatography–photodiode array detection (HPLC–DAD), with the combination of chromatographic fingerprint analysis. Separation was achieved on a C18 ODS 80TS QA analytical column with linear gradient elution of acetonitrile and 10% formic acid and 0.1% trifluoroacetic acid (TFA) aqueous solution. Our results showed that the contents of anthocyanins of dried L. ruthenicum Murray from different origins were different. We also inferred the anthocyanin compositions of dried L. ruthenicum Murray through analyzing the UV spectrum, retention time, elution order, and MS data. Finally, eight kinds of anthocyanin compositions were identified and different from the anthocyanins in fresh L. ruthenicum Murray. In a word, this study may provide experimental data in further development and utilization of L. ruthenicum Murray. 相似文献

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%).

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%).

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.

The chemical constituents of leaf oils of Elephantopus scaber L. from 12 locations in Southern China, including three provinces and Hong Kong, were investigated using GC/MS. A total of
24 compounds were detected, of which 20 were identified by their mass spectra fragmentation patterns. The major compounds
include hexadecanoic acid (8.19–39.22%), octadecadienoic acid (trace - 29.22%), five alkane homologues, i.e., n-tetradecane
(1.19–5.26%), n-pentadecane (3.22–12.05%), n-hexadecane (2.38–16.26%), n-heptadecane (2.48–15.32%), and n-octadecane (1.39–9.59%),
as well as tetramethylhexadecenol (2.06–4.31%). Hierarchical cluster analysis classified the leaf oils into two groups. Two
main chemotypes of leaf oils in E. scaber were thus identified, one rich in hexadecanoic acid and octadecadienoic acid, and the other rich in the five alkane homologues.

Chemical compositions of 16 Artemisia herba-alba oil samples harvested in eight East Moroccan locations were investigated by GC and GC/MS. Chemical variability of the A. herba-alba oils is also discussed using statistical analysis. Detailed analysis of the essential oils led to the identification of 52
components amounting to 80.5–98.6 % of the total oil. The investigated chemical compositions showed significant qualitative
and quantitative differences. According to their major components (camphor, chrysanthenone, and α- and β-thujone), three main groups of essential oils were found. This study also found regional specificity of the major components. 相似文献
