Chemical Pollutants

The two varieties of soybean (Soybean Bragg and Soybean JS-71-05) were collected from an industrial site (IS) and from a non-industrial site (NIS) for the study of their chemical composition and fatty acids profiles by gas liquid chromatography (GLC). These studies revealed large changes in the major and minor fatty acids of the soybean seeds due to the effect of chemical pollutants. There was a significant decrease in the amounts of major and minor fatty acids, such as myristic acid (14:0), palmitic acid (16:0) stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2), and linolenic acid (18:3), in the seeds from industrial site. The changes in the chemical composition due to chemical pollutants showed mixed results.

Proximate Analyses

Anethum sowa L. (Dill) seeds were investigated to determine the fatty acid composition and proximate analyses. The seeds contain 9.36 % fatty oil. The saturated and unsaturated fatty acids contributed 6.22% and 93.78% respectively of the oil. The per cent composition of the extracted oil was identified by Gas Liquid Chromatography (GLC). Among the six fatty acids identified from this study oleic acid contributed the highest proportion (87.10%), where as, linolenic, palmitic, stearic, behenic and arachidic all together contributed the rest (12.90%). Proximate analyses showed that A. sowa. seeds are good source of dietary fibre. Overall Dill seeds oil can be considered as a good source of oleic acid.

Heartwood Extractives

The heartwood of Canadian Alpine larch was found to contain 4.8% acetone-soluble material. From this extract taxifolin and aromadendrin were isolated in 26% and 17% yield, as well as conidendrin in a small amount. About one-quarter of the extract was composed of esters of phthalic, ferulic, and fatty acids. After saponification β-sitosterol, nonan-2-ol, phthalic acid, and a mixture of fatty acids were isolated. Gas-liquid chromatography indicated the presence of palmitic, an unidentified C16, stearic, oleic, linoleic, linolenic, an unidentified C20 acid, and two unidentified alcohols.

One Year

The content of fat in carp (Cyprinus carpio) tissue was evaluated throughout one year. The following tissues were evaluated: skeletal muscle, soft roe, hard roe, fat tissue, and hepatopancreas. Respective fatty acids were determined using gas liquid chromatography (GLC). The highest content of valuable polyunsaturated acids, like eicosahexaenoic acid, was found in soft roe and in skeletal muscle during summer, in hepatopancreas during spring, in hard roe during fall. The content of eicosahexaenoic acid in hard roe remains high in all seasons except summer. Saturated fatty acids like palmitic acid and stearic acid do not fluctuate very much throughout the year. The maximum concentration of oleic acid was found in summer. Differences in fatty acid concentration among different carp tissues depended on the living style, but their variation in the same tissue within the year depended on the main fodder of fish.

The chemical composition of the secretions from the anal sacs of three species from the genus Genetta has been analysed by means of gas-liquid chromatography and mass spectrometry. The main constituents of the secretion are free fatty acids, hydrocarbons, mono- and diester waxes, triglycerides, alkane diols, and free alcohols. Composition of the secretion in the three species is fundamentally similar, but there are some remarkable quantitative differences of the components m entioned. Some of the alkane-1,2-diols in these secretions have never been found before in nature.

Carum roxburghianum Benth. (Radhuni) seeds of three different places of Bangladesh were investigated to determine the fatty acid composition and physico-chemical properties of extracted oil. The seeds were found to contain oil ranging from 15.31 to 20.32%. The percentage compositions of fatty acids were identified and quantified by Gas Liquid Chromatography (GLC). The saturated and unsaturated fatty acids in extracts were 4.95 to 6.27% and 93.73 to 94.89%, respectively. Among six fatty acids identified in this study, oleic acid contributed the highest portion (76.44 to 79.16%), whereas, linoleic (1.38%), linolenic (15.28 - 15.40%), stearic (0.70%), palmitic (4.95 - 5.57%) and ecosenoic acid (0.51 - 15.73%) together contributed the rest. Physico-chemical properties of the oil extracted were also investigated. The specific gravity, refractive index, optical rotation were recorded as 0.903 to 0.918 at 30°C, 1.465 to 1.470 at 30°C and +8.54° to +9.56° at 26°C, respectively. The chemical properties like saponification value (183.52 - 193.45), iodine value (80.99 - 120.90), peroxide value (23.25 - 36.16), acid value (143.84 - 162.99), ester value (48.12 - 62.03), percentage of unsaponifiable matter (3.56 - 6.51%), Reicher-Meissel value (2.00 - 3.12), Polenske value (4.12 - 6.20) and Henher value (85.12 - 95.56) were determined. Overall Radhuni seeds oil can be considered as a good source of oleic acid. Keywords: Carum roxburghianum; Radhuni seed oil; fatty acid composition; oleic acid; Gas Liquid Chromatography.

Callus Cell

The physiological characteristics of the callus cell cultures of Alhagi persarum Boiss et Buhse, a member of the legume family, widely used in folk medicine, have been studied. It was shown that the source of the explant was an important factor in the initiation of callusogenesis: more intense callusogenesis (almost 100%) was observed for explants from various organs of sterile seedlings, rather than intact plants (less than 30%). As a result, more than 20 lines of morphologically different callus cell cultures were obtained, and the growth parameters for the 5 most intensively growing lines were determined. The composition of fatty acids (FA) of total lipids and secondary metabolites in the most physiologically stable callus line Aр-207 was analyzed. Using capillary gas-liquid chromatography with mass spectrometric detection (GLC-MS), 19 individual C12--C24 FAs were identified, the main fraction of which were palmitic (~ 23%), stearic (~ 22%), linoleic (~ 14%) and α-linolenic (~ 33%) acids. The established atypical ratio of FAs (a simultaneous high content of both saturated FAs and polyunsaturated α-linolenic acid) is possibly due to the adaptation of cells to in vitro growth conditions. Phytochemical analysis of the secondary metabolites was carried out using ultra-performance liquid chromatography with electrospray ionization mass spectrometric detection (UPLC MS). Compounds belonging to different structural groups of isoflavones were found. Aglycones (calycosin, formononetin and afrormosin isomer), glucosides (formononetin glucoside), as well as esters of glucosides (malonylglycosides of calicosin, formononetin, afrormosin isomers, glycitein and genistein) were detected. These secondary metabolites are widespread in plants of the Fabaceae family; however, isoflavones are rare in representatives of the Alhagi genus. The presence of malonylated isoflavone glycosides in Alhagi spp. was shown for the first time. endemic plant species, Alhagi, in vitro cell culture, callus cell culture, isoflavones, fatty acids All studies were carried out using the equipment of the "Experimental Biotechnological Facility" and the "All-Russian Collection of Cell Cultures of Higher Plants" of IРР RAS.
