A GC-MS Metabolic Study on Lipophilic Compounds in the Leaves of Common Wheat L.

Common wheat ( L.) is one of the most valuable cereal crops worldwide. This study examined leaf extracts of 30 accessions of and its subspecies using 48 h maceration with methanol by GC-MS and GCxGC-MS.

A GC-MS Chemotaxonomic Study on Lipophilic Compounds in the Bark of subsp. Trees from the Population Growing in Akademgorodok, Novosibirsk (Russia).

Determination of chemotypes and of their role in the polymorphism of populations is an important field in the research on secondary metabolites of plants. In the present study, by gas chromatography coupled with mass spectrometry, the composition of bark extracts from rowan subsp. was determined for 16 trees growing within Akademgorodok of Novosibirsk, with bark samples collected both in winter and summer.

Recombination of X-ray-Generated Radical Ion Pairs in Alkane Solution Assembles Optically Inaccessible Exciplexes from a Series of Perfluorinated -Oligophenylenes with ,-Dimethylaniline.

We demonstrate that a series of perfluorinated -oligophenylenes CF-(CF)-CF ( = 1-3) produce exciplexes with ,-dimethylaniline (DMA) in degassed X-irradiated -dodecane solutions. The optical characterization of the compounds shows that their short fluorescence lifetimes (ca. 1.

Spin effects as a tool to study photoinduced processes in (S/R)-ketoprofen-(S)-N-methylpyrrolidine dyads.

(S/R)-Ketoprofen (KP) is considered to be the strongest photosensitizer among nonsteroidal anti-inflammatory drugs. The photosensitizing reactions are caused by a substituted benzophenone chromophore. It produces various toxic effects through the formation of active paramagnetic intermediates and photoproducts able to attack biological substrates.

GC-based chemoprofile of lipophilic compounds in Altaian sample.

The presented data contains information about component composition of lipophilic compounds in fungal body sample obtained using gas chromatography and subsequent mass spectrometry.

Hypotensive and neurometabolic effects of intragastric Reishi (Ganoderma lucidum) administration in hypertensive ISIAH rat strain.

Background: As the standard clinically used hypotensive medicines have many undesirable side effects, there is a need for new therapeutic agents, especially ones of a natural origin.

Purpose: One possible candidate is extract from the mushroom Reishi (Ganoderma lucidum), which is used in the treatment and prevention of many chronic diseases.

Study Design And Methods: To study the effectiveness of Reishi, which grows in the Altai Mountains, as an antihypertensive agent, we intragastrically administered Reishi water extract to adult male hypertensive ISIAH (inherited stress-induced arterial hypertension) rats.

Difficulties in building radiation-generated three-spin systems using spin-labeled luminophores.

Aromatic compounds are well-known acceptors of primary radical ions that are formed under high-energy irradiation of nonpolar systems. Thus formed radical ion pairs recombine and produce magnetosensitive fluorescence, which helps study the short-lived radical ions. It was initially suggested that a simple introduction of a spin label into the original arene would allow an easy transition from two-spin to three-spin systems, retaining the experimental techniques available for radical pairs.
