Ammothamnus lehmannii 
Bunge
 –
belongs to the leguminous family 
(Fabaceae)
is a 
semi-shrub plant 30-50 cm high. The stem is strongly branched from the base, the 
branches are straight, 5-10 cm long. Petals are in white color. The seeds are yellowish 
brown, gilded, oval-spherical. It blooms in April-June, gives fruit in June - July. It 
reproduces with the help of seeds. Life expectancy is 10-20 years. It grows in the plains, 
mainly on sandy and loamy soils, desalinated barrens, stony sandy soils. It has sand-
strengthening and decorative properties, and can be used for beautification of 
settlements. 
Alkaloids and flavonoids are stored in the above-ground part of the plant up to 0.6-
4%. The seeds and roots contain sophocarpine, an alkaloid with antirheumatic and 
ganglioblocking properties. According to its chemical composition, it contains plant 
dyes flavonoids, carotenoids, anthraquinones, naphthaquinones and beta-cyanins. 
Among them, flavonoids such as luteolin, quercetin, synaroside, and rutin are used in 
medicine due to their astringent, antioxidant, and complex-forming properties. 
A decoction of the root is used in folk medicine to treat rheumatism. 
In 2021-2022, we studied the distribution of 
Ammothanus lehmanni
in the Navoiy 
region (Kizilkum) of Uzbekistan and learned its root stock. 
We have determined the distribution and biological reserves of 
Ammothanus 
lehmanni
on the Zarafshan-Davgistag road in the vicinity of the Amantag mine, 
Davgistag mine, Balakaral village, Karakata village and Kuljuktog region in Navoiy 
region. Forms an association with 
Ferula foietida
. The association includes 
Convolvulus 
subsericeus, Iris songorica, Carex pachystilis, Artemisia terrae-albae
, and other plants, 
in addition to the bitter bush and the stinking carpet. 
The distribution area of
Ammothamnus lehmanni 
on the Zarafshan-Davgistag road: 
around the Amantag mine - 255 hectares, around the Davgistag mine - 275 hectares, 
around the village of Balakaral - 330 hectares, around the village of Karakata - 156 
hectares, around Kuljuktog - 1071 hectares; its biological reserve: around the Amantag 
mine - 48.45±1.27 t, around the Davgistag mine - 44.0±1.37 t, around the village of 
Balakaral - 59.40±1.65 t, around the village of Karakata - 32.76±0.78 t, around the 
village of Karakata - 32.76±0.78 t, around Kuljuktog - 246.33±5.35 tons and its 
exploitation reserve: around the Amantag mine - 42.33±0, 51 t, around the Davgistag 
mine - 35.2±0.55 t, around the village of Balakaral - 47.52±0.66 t, around the village of 
Karakata - 24.65±0.31 t, around the village of Karakata - It was 24,650.31 tons, around 
Kuljuktog - 172.43±2.14 tons. 
In general, the distribution area of 
Ammothanus lehmanni
in Navoiy region 
(Kizilkum) was 2087 hectares, its biological reserve was 430.94±10.42 tons, and its 
extractive reserve was 322.13±4.17 tons.
