The Aral Sea desiccation is known to result in the desertification of the whole Aral
Sea region. Of high significance are the studies on biology and ecology of species
widely distributed in the region, on biochemical composition
of promising medicinal
plants and identification of bioactive compounds in them for research to be conducted
aiming at using them in the pharmaceutical industry.
Atriplex is a plant genus of about 250 species, known by the common names of
saltbush and orache,
belonging to the subfamily
Chenopodioideae
of the family
Amaranthaceae s.l
. widely spread in the Southern Aralkum.
The work was initiated to determine carbohydrate percentage composition in
Atriplex
pratovii
Sukh and
Atriplex tatarica
L.
Atriplex pratovii
Sukhor. is an annual herbaceous plant reaching the height of 30-
120cm. It has the erect branched stem covered with the silvery hairs and large smooth
(with folds in some places) leaves arranged in a row
having solid edges and well-
developed ridges.
Atriplex tatarica
L. is a branched annual herbaceous plant reaching the height of 60-
100 cm flowering and fruiting in August-September. The leaves are alternately
triangular-ovoid or oblong-ovoid.
A number of researchers have studied lipid composition of the
Atriplex lentiformis
plants growing
at various temperatures, concentrations of chemical elements found in
Atriplex pratovii
Sukhor, some bioactive compounds found in
Atriplex halimus
as well
as antioxidant activity of the latter.

Atriplex pratovii
1.17±0.06
0.81±0.14
0.31±0.01
-
2.29±0.03
As it can be seen, there was different carbohydrate percentage
composition in the
Atriplex pratovii
(Table)
.
Thus, fructose percentage (1.17±0.06) was higher than those
of glucose (0.81±0.14) and sucrose (0.31±0.01), while the total sum of carbohydrates
was 2.29±0.03%.
In the
Atriplex tatarica
, the total sum of carbohydrates was 1.29±0.06%, while there
was no significance difference in the carbohydrate percentage compositions of fructose
(0.6±0.16) and glucose (0.55±0.11); the sucrose percentage composition was found low
(0.13±0.10). No traces of maltose were found in either plant. Thus, in
Atriplex pratovii,
the carbohydrate percentage was found two times higher than in
Atriplex tatarica.
