ABSTRACT: Previously known biogenic stimulator humic acid (HA) was the subject of this current study and HA
based new remediation was developed by addition of silver (Ag) nanoparticles in its macromolecule. Extracted HA
from a healing mud was characterized and used as reducing agent for Ag ion as well as a stabilizer for the formed Ag
nanoparticles. The properties of the obtained hybrid composite were examined by XRD, UV and FTIR spectroscopic
techniques. The diameter of the nanoparticles in the HA polymer was up to 8.6 nm and they were identified to be
metallic Ag.

ABSTRACT: The objective of this study was to determine the meat quality and fish oil’s physical and chemical
characteristics of the Mongolian fishes: Syrok (Coregonus peled), and Lenok (Brachymystax lenok). Lipid content was
3.1 to 14.15%, moisture was 72.14 to 80.5%, protein content was 8.54 to 9.8% and total mineral element was 0.5 to
3.1%. The caloric value Lenok (Brachymystax lenok) was 68.7 and Syrok (Coregonus peled) - 142.8 Kj/100g,
respectively. Minerals included potassium (46.32 to 52.22%), phosphorous (39.06 to 41.3%), calcium (3.26 to 5.87%),
magnesium (2.08 to 3.97%) and silicon (1.14 to 2.24%), while zinc, iron and copper were present intrace amounts.
Eight non essential amino acids with total amount of 58.61 to 59.64% were identified, and histidine detected as in
highest value in all the species, followed by arginine. The data showed that the Mongolian fishes are of high nutritional
value and good source of proteins, minerals as well as non essential amino acids. The physical and chemical
characteristics of Syrok (Coregonus peled), and Lenok (Brachymystax lenok) fish oil were analyzed. These parameters
are: iodine value (IV), peroxide value (PV), acid value (AV), saponification value (SV), percentage of free fatty acid
(%FFA), refractive index (RI) and colour.
The extracted lipid content obtained from muscles of Syrok and Lenok was about 14.15% and 3.1%. The percentages of
unsaturated fatty acids were higher than saturated fatty acids accounting for 74.37% and 25.6%, 83.83% and 16.46%

ABSTRACT: Enzymes in the soil are closely related to the physical, chemical and biological characteristics of the soil
and regulate the formation of soil fertility, organic matter, nutrient mineralization and cycling in nature. Soil contains
phosphatase, urease, dehydrogenase, catalase, peroxidase, saccharase, protease, amylase, β-glucosidase, arylsulphatase
and other enzymes. The purpose of the given work was estimation of catalase protease and urease activity on three
different types of soil as high mountained steppe and dry steppe roughly humusified soil; mealy brown carbonated soil
and mountain meadow forest soil which are common in the mountain and steppe regions of our country in correlation
with soil depth and anthropogenic impacts. In all soil samples the highest enzymatic activities were detected in the
depth of 0-15 cm from the soil surface. For all soil samples the enzymes activities decreased more rapidly with
increasing soil depth affected to anthropogenic impacts in comparison with samples not exposed to human impacts.

ABSTRACT: It was shown that the plant Peucedanum baicalense (Redow.) Koch is the source of valuable coumarins.
Five linear furocoumarins – isoimperatorin, fellopterin, 8-(1,1-dimethylallyloxy) bergapten, deltoin and marmesin were
isolated from the roots of Peucedanum baicalense (Redow.) Koch. The structures of these compounds were elucidated
by spectroscopic methods. The cytotoxicity of isoimperatorin, fellopterin, 8-(1,1-dimethylallyloxy)bergapten and
deltoin was studied on models of human СEM-13, MT-4 and U-937 tumor cells. Compound 8-(1,1-
dimethylallyloxy)bergapten had the greatest cytotoxicity.

ABSTRACT: Wines were made from Grьner Veltliner and Zweigelt and cultivars were grown in four different
geographical regions of Austria and Czech Republic; two wineries in Austria (Poysdorf, GroЯriedenthal) and two
wineries in the Czech Republic (Velkě Bнlovice, Bošovice). Eleven individual phenolics were quantified using a
HPLC/UV-VIS method.

ABSTRACT: We have studied physicochemical properties and yield of free and linked organic compound, mineral
components, element and yield of macromolecular compounds of healing mud, which is collected from Holboolj Lake.
Minerals enter peloids underground as well as from the surface. They are leached out of the surrounding earth into the
peloid bed. We determined microcline -K(Si3AI)O8, quartz- SiO2 which is most common mineral on the face of earth
and albite - Na (AISi3O8) by X-Ray diffraction analysis. The organic matter of medical mud investigated using
chemical analysis and analytical technique. Some classes of biomolecules including humin, lipid, and carbohydrate
were identified. Humic acid which is the major part of peloid organic matter concentration varied 0.59% and 41.54% of
total organic matter of peloid. Composition of organic matter in peloid is to affect its chemical and physical property
and to empower bio-chemical process in mud. Holboolj Lake belongs to continental hydrosulfide peloid.

ABSTRACT: On the basis of proximate, ultimate, petrographic and IR analysis results have been confirmed that the
Khoot coal is a middle-rank D mark stone coal and Tsaidamnuur coal is a low-rank B mark lignite brown coal. The
results of X-ray fluorescence analysis of coal ash show that the Khoot and Tsaidamnuur coals are subbituminous coal.
The ash of Khoot coal has an acidic character and the ash of Tsaidamnuur coal has an alkaline character. The results of
pyrolysis of Khoot coal at different heating temperatures show that a maximum yield-10,3% of liquid product can be
obtained at 600oC. Also the results of pyrolysis of Tsaidamnuur coal at different heating temperatures show that a
maximum yield-13,7% of liquid product can be obtained at 500oC. The results of thermal dissolution of Khoot coal in
tetralin with constant mass ratio between coal and tetralin (1:1,8) at 450oC show that 60,8% of liquid product can be
obtained after thermal decomposition of the coal organic mass. Also the results of thermal dissolution of Tsaidamnuur
coal in tetralin with constant mass ratio between coal and tetralin (1:1,8) at 450 oC show that 80,0% of liquid product
can be obtained after thermal decomposition of the coal organic mass.

ABSTRACT: Sea buckthorn (H.rhamnoids L.), a member of the family Elaeagnaceae, is a deciduous spiny shrub or
small tree and widely distributed in cold regions of Mongolia such as Khangai, Mongol Daguur, Khovd, Mongol Altai,
Gobi Altai and Great Lakes regions. They are rich source of vitamins (especially vitamin C), sugars, organic acids and
bioactive compounds. We have conducted biochemical and phytochemical studies of leaves Mongolian Sea buckthorn
varieties (Ayaganga, B-32, and Prevoskhodnaya). The contents of flavonoids and proteins in Mongolian sea buckthorn
leaves were ranged 0.29-0.35%, 16.43-19.50%. We conclude that leaves of Sea buckthorn growing in Mongolia contain
similar biologically active substances and vitamin C (110.8-154.3 mg%) like berries and might be serve as raw material
for producing of essential dietary products.

costunolide, alkaloids and testosterone were detected in Garidi-5. Methanol extract of Garidi-5 showed the highest
(95.11%) DPPH radical scavenging activity at concentration of 0.05 µg/ml. Moreover, Garidi-5 significantly reduced

ABSTRACT: At present, over 90% of Mongolian electricity is produced by combined heat and thermal power stations.
The main coal deposits used for Central power system's power stations are Baganuur, Shivee-ovoo lignite type coal and
Shariin gol bituminous coal. In Mongolia almost 600,000 tonnes of coal combustion by-products are disposed of in
waste ponds. In this paper we report preliminary characterisation of Mongolian coal combustion by-products including
fly ashes sourced directly from thermal power stations and ash retrieved from ponds. It was determined that fly ashes
generated from Baganuur and Shivee-ovoo coal deposits are class C, while ash from Shariin gol coal is class F
(according the ASTM C618). All ash products were characterised by chemical, mineralogical, granulometrical,
porosity, FE-SEM and radiation methods. Fly ashes sourced directly from power stations were found to be more
suitable for manufacture of geopolymers for building materials application.

ABSTRACT: In this study the contents of total nitrogen, crude protein, easy extracted protein and the compositions of
free and protein’s amino acids in five wood-rotting fungi, growing in Mongolia were analyzed. All those fungi are
medicinal and the medicinal use of them has a very long tradition in the Asian countries. Dried wood-rotting fungi
Fomitopsis officinalis (Vill. ex Fr.) and Inonotus obliquus (Pers. ex Fr.) contain very low crude protein (8.06% and
9.12%, respectively) in comparison with edible mushrooms. The protein content of the other 3 species Fomes
fomentarus (L. ex Fr.), Fomitopsis pinicola (Schwarts. ex Fr.) and Laetiporus sulphureus (Bull. ex Fr.) were range from
20.79 to 28.31% such as in most medicinal mushrooms. All investigated fungi are a good source of brain amino acids as
aspartic and glutamic acids. A high amount of essential free amino acids such as tryptophan, cysteine and methionine
was determined in all investigated wood-rotting fungi although some of them showed a low content of protein.

ABSTRACT: In this study, Fe-Mn-CO3 layered double hydroxides (Fe-Mn LDHs) and Fe-Mn double oxide (Fe-Mn
DOs) were prepared by the co-precipitation methods to remove arsenite and arsenate. The physico-chemical
characteristics of adsorbents were analyzed by X-ray diffraction, X-ray photoelectron spectrum, Fourier transform
infrared spectroscopy and scanning electron microscopy. The adsorption characteristics of arsenite and arsenate were
investigated in points of adsorption kinetics, isotherms, and thermodynamics usaing batch and column experiments.
The adsorption of As(III) onto Fe-Mn LDHs and Fe-Mn DOs were occurred five times faster than that of As(V), where
pseudo-second order model was well fitted with the experimental data compared to other kinetic models. The
adsorption capacity of arsenic from solution by Fe-Mn LDH and Fe-Mn DOs were more fitted to both the Langmuir
and Freundlich isotherms compared to Temkin and Dubinin-Radushkevich adsorption isotherm models. The adsorption
of arsenic onto the Fe-Mn LDH and Fe-Mn DOs increased with the decrease in pH because of more positive charge of
surface due to protonation.The results indicate that the Fe-Mn LDHs and Fe-Mn DOs are a novel and excellent
adsorbents for the removal of arsenic.

ABSTRACT: The role of carbon black is especially important in cokeless metallurgy. Carbon black can be isolated at
less hot zones (less than 720oC) in metallurgical ovens according to equation of Buduara: 2CO = C +CO 2. The
particles of carbon black obtained by the reaction of Buduara are characterizing with complicated open-work structure
including globular amorphous parts and graphitized crystalline elements connected by crosspieses with size in
nanometric range ( from 0,1 µm to  3µm). The carbon black is characterizing with increased Gibbs’s energy and high
kinetic activity because of its dispersed and amorphous structure.

ABSTRACT: Total flavonoids, anthocyanins and hydrolysable tannin’s contents were determined in water and
alcoholic extract in different parts of Rumex acetosella L. Antioxidant assays and brine shrimp cytotoxicity assay were
followed. Maximum amount of flavonoid (59.67±0.4 mg/g) determined in leaf’s ethanolic extract, the hydrolyzable
tannins - in root’s ethanolic extract (94.78±1.45 mg/g) and the anthocyanins (0.14%) in flower’s ethanolic extract.
Maximum correlation occurred between hydrolyzable tannins and reducing power or antioxidant capacity (p = 0.001,
R2 = 65.5% and 85.8%, p = 0.001, respectively). In preliminary result of brine shrimp assay, significant deaths of
nauplii were observed only in root extracts (LD50≈160µg/ml in ethanol and≈1000 µg/ml in water extract).

ABSTRACT: The main goal of this research is to synthesize new candidates of chlorin based photosensitizers and to
evaluate their the antitumor photodynamic effect. In this research we used A549 (human lung carcinoma cell). The
cytotoxic activity was measured by microculture tetrazolium (MTT) assay, and morphological changes induced by PDT
were checked by microscopy. The cytotoxic effect of photosensitizers was shown to increase depending upon the
concentration of photosensitizers. New chlorin derivative photosensitizers were low toxic to tumor cells in the absence
of light, while there was remarkable tumor cell death after photodynamic therapy.

ABSTRACT: We have synthesized mono and bimetallic catalysts (Pd,Ag, Pd-Ag, Ag-Pd) supported on γ-Al2O3 by
the sequential impregnation method. The bimetallic catalysts were prepared with a fixed Pd loading (4 wt.%) by
incipient impregnation of one metal precursor and calcination, followed by the impregnation of the second metal
precursor and a second calcinations step. Obtained materials were characterized by TEM, XRD and IRAS and
catalytic test measurements. The temperature programmed CO oxidation and IR results showed that the bimetallic
catalysts consisted of alloyed nanoparticles and indicated that the surface mainly consists of isolated Pd atoms in
a Ag matrix. The catalytic activity of the catalysts for hydrodechlorination of TCE was tested. For the pure Pd/γ-
Al2O3 catalyst, the catalytic activity was observed in the hydrodechlorination reaction of TCE. The catalytic
performance of the bimetallic samples was poor under these conditions, but may be increased by changing the Pd/Ag
ratio or the H2/TCE ratio e.g. during reaction.

ABSTRACT: Protopine is an isoquinoline alkaloid contained in plants in northeast Asia. In this study, we investigated
whether protopine derived from H. erectum L could suppress lipopolysaccharide (LPS)-induced inflammatory
responses in murine macrophages (Raw-264.7cells). Protopine was found to reduce nitric oxide (NO), cyclooxygenase-
2 (COX-2) and prostaglandin-E2 (PGE2) production by LPS-stimulated Raw-264.7 cells, without a cytotoxic effect. Pre-
treatment of Raw 264.7cells with protopine reduced the production of pro-inflammatory cytokines. These inhibitory
effects were caused by blocking phosphorylation of mitogen-activated protein kinases (MAP kinases) and also
blocking activation of a nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB). Also cytotoxic and
antiproliferative activities of the protopine on tumour (LSCC-SF-Ms29, LSR-SF-SR) and nontumour (L 929, MDBK)
cells were evaluated. The maximal nontoxic concentrations (MNC) as well as concentrations required to reduce cell
viability by 50% (CC50) at 24h and 48h were determined using the trypan blue dye exclusion test. Comparable CC 50
(24h) data were obtained for protopine (25µM; 92 µM) and mytomycin C (24 µM≥30 µM) for LSCC-SF (Ms29) and
LSR-SF(SR) cells, respectively. In MNC the alkaloid decreased the proliferation of LSCC-SF-Ms29, MDBK and L929
by 58, 42, 19 and 21%, respectively. The alkaloid was much less toxic and cytostatic for cells from L929 and MDBK as
compared to cells from tumour lines. The compound inhibited the colony-forming ability of tumour cells in a dose
dependent manner. In doses ≥0.001 µM the protopine blcked the colony-forming capacity of normal murine-marrow

ABSTRACT: The wash ability of coal sample from seam number 4 of Baganuur deposit, which is located in Nyalga-
Choir basin, was studied. The proximate and ultimate analyses of the sample were done by standard methods. The
sample was crushed and pulverized in order to obtain 3 fractions with particle sizes of 3-1.5mm, 1.5-1.0mm and 1.0-
0.63mm. Heavy liquids were obtained by dissolving different amounts of ZnCl 2 salt in water. The liquids having <1.3;
1.3-1.4; 1.4-1.5; 1.5-1.6; 1.6-1.7; 1.7-1.8 and >1.8g/cm3 densities were used for float sink test of the fractions. Float
sink test was done by using Russian standard GOST 4790-93. Results of the proximate and ultimate analyses showed
that the coal has Vdaf=47.0%, Ad=13.3%, Cdaf=70.53%. According to the coal classification, the coal belongs to the B2
class of brown coal. Yields and ash contents of the fraction with 3-1.5mm, 1.5-1.0mm particle size were 51.8 and 7.7%,
46.6% and 7.4% respectively, when for the separation was used heavy liquid with 1.4g/cm 3 density. In general, it can be
concluded that the Baganuur coal belongs to the category of coals with very poor washability.

ABSTRACT: This study was aimed to evaluate the antioxidant and cytotoxic activities, hepatoprotective effects of the
aerial parts of Hyoscyamus niger L. grown in Mongolia. The ethanol crude extract of H.niger L. was suspended in
water and consequently fractionated with hexane, chloroform, ethyl acetate and butyl alcohol. All of the fractions were
examined for their antioxidant and cytotoxic activities by using DPPH and MTT assays, respectively. Hexane fraction
showed the highest DPPH radical scavenging activity at concentration of 50 µg/mL by 87.36% with the IC 50 value of
18.16 µg/mL. MTT results showed that ethyl acetate fraction demonstrated significant cytotoxicity against A549 cell
line, with values of 90.47% at 48 h (50 µg /mL). The water fraction notably protected HepG2 cells against the
cytotoxicity of t-BHP than EGCG. H.niger L. is an important medicinal plant and reported to be used for the treatment
of various ailments.

ABSTRACT: Adsorption of heavy metal ions specifically, Cu (II), Zn (II), As (V) and Cr (VI) from waste
water by modified zeolite was evaluated. The modified zeolite was synthesized previously by
dehydroxylation of low grade at 450°C and reacted hydrothermally with 2-4 M NaOH solution at 100°C for
2 h. The adsorption capacity decreased in the order Cu(II) > Zn(II) > As(V)>Cr(VI) ions. Almost complete
adsorption was achieved for Cr(VI) was 91% and 52.3% at pH 7.0 and 8.4, respectively. The results also
showed that the grain size of the modified zeolite has a little effect on the adsorption capacity. The
experimental data was compared with two adsorption isotherms, Langmuir and Freundlich isotherms. The
experimental results showed a good agreement with the Langmuir plots .
